    These 40 posts are a mostly 'bitches' from people who 'claim' Anandtech reviewers are 'wrong' ?

    In case it is not already obvious, Anandtech is an enthusiast site, which means they cater to the overclockers, and people who care about computer hardware in general, not people who can not sleep when someone drops a pin over in china . . .

    Seriously, I can understand pointing out typos, and a disagreement or two on the finer points, and what not, but complaining because you think their data is incorrect, based on data given by another site(which obviously is not even in the same class of a site), is plain stupid. Do you actually know for a fact that the data from this other site is correct ? If so, how do you know ? If 30dba is what is considered a quite room, wtf does it matter if Andantech 'claims' the fan used here is 14dba or not ? Personally, I think some of you guys, are entirerly too anal, and need to learn how to socialize a tad better. something like: 'I do not think 14dba is possible on a computer fan(Correct me if I am wrong), but <insert some other point here>' probably would have worked just fine, without sounding like you are bashing the reviewers of the site.

    There are many ways to say that you think the data given is incorrect, without sounding like a horses ass, and in the long run, no one is twisting your arm to come here and read the reviews. If you really, really like this other site so much, that you feel it nessisary to come here and bash the Anandtech crew, I think we all can agree, it would be a much better place here, if you just stayed away.

    Real world testing is great, but isnt this how someone's Core 2 duo article got FLAMED to death because there was a bottleneck?

    When we test fans, yea it's great to know that 14 dB fan won't do jack in my system when my PSU is running around 30.

    Just like it doesn't matter that my sticks of RAM can clock to DDR600 because my Opteron 170 won't let me go past 250 HTT anyways, so I can only go to DDR500 anyways unlesss I really want a lower multiplier.

    There are limits left and right, but EVERYONE wants to know the specifications and capabilities of THE PRODUCT IN INTEREST. This is similar to high school science or junior high or whenever you learn that in experimenets, your goal is to isolate one variable and test it.

    I don't give a damn that my PSU is going to be loud. What if i used a fanless system? There are people out there who want to know how loud this damn SilenX fan is, and we wnat to know how loud it REALLY IS compared to the specs.

    I'm tired of hearing how really only REAL WORLD performance matters. Give us the LAB numbers and then give us how real world performance might come into play.

    As an engineer, when you look up materials properties like strength tests, hardness numbers, stress concentration data, it's ALL lab samples that are perfect. It's your job when you choose a material to use in applications to understand the real world implications.

    Similarly, it's your job to understand that when you pick up a 14 dB fan, that your PSU may still be louder and that your system may not be that quiet.
  • DrMrLordX - Friday, April 6, 2007 - link

    The "product in interest" is the HSF itself, not the add-on fan. The whole point of adding the fan, I suppose, was to show that the included fan produced as much (or more) noise while yielding significantly inferior results.

    The HSF still wasn't that great even with the add-on fan, so it's all rather academic to me. Unless this HSF sells for a very low price, I can see no reason to shell out ~$50-$60 for it + the SilenX fan when you can get a cooler that performs better for the same amount of money. Choose wisely, and you might even get one that's just as silent.

    People need to stop making a mountain out of a mole-hill here. Geez.
  • strikeback03 - Friday, April 6, 2007 - link

    then go read over at SPCR. They try and tell you how loud each component is, Anandtech tries to tell you whether it matters. no point in repeating tests easily available elsewhere.
  • Affectionate-Bed-980 - Saturday, April 7, 2007 - link

    Yes I know that. It's great going to SPCR to see good sound testing, but it's just a PITA that I have to hit up like 10 different hardware sites to get information.

    I like the noise testing, but at least in my systems I have a problem with hi freq fan whine. It would be nice in your fan review if you could get a spectrum analyzer and look for noise spikes as well as average dBa.
  • Wesley Fink - Thursday, April 5, 2007 - link

    For those that have complained that our 36db ambient room noise is very high I am posting info from SilentPCReview's article "Noise in COmputing: A Primer" at http://www.silentpcreview.com/article121-page1.htm...">http://www.silentpcreview.com/article121-page1.htm....

    SPL (dB) TYPICAL ENVIRONMENT AVERAGE DESCRIPTION
    140 30 meters from military aircraft at take off Threshold of pain
    120 Boiler shop (maximum levels)
    Ships engine room (full speed) Almost intolerable
    100 Automatic lathe shop
    Platform of underground station (maximum levels)
    Printing press room Extremely noisy
    80 Curbside of busy street
    Office with tabulating machines Very noisy
    60 Restaurant, Department Store; Noisiest Gamer PC Noisy
    50 Conversational speech at 1 meter; Noisy workstation Clearly audible
    35 - 45 Quiet office or library; Typical PC Subdued
    25 - 30 Bedroom at night, Quiet PC Quiet
    20 - 25 Quiet whisper; Very quiet PC
    Background in TV and recording studios Very quiet
    15 - 20 Super quiet / fanless PC Barely audible
    <15 Sounds of internal organs Normally inaudible
    0 'Normal' threshold of hearing Not audible

    As you can see 35 to 45db is considered a Quiet Office or Library or the noise level of a Typical PC Subdued. At 36db I am at the low end of that noise category. When you discuss noise it is useful to keep these comparisons in mind.

    In the revamping of our test bed we will be aiming to drop into the next category if possible using realistic means in our test romm and test platform. We have stated in our reviews that we measure noise at a constant distance above the open side of a system mounted in a PC Case. As we have also said this means you should consider our noise measurements the worst case you will see for the component tested. A closed case reduces noise and greater distance from the component reduces noise. Any measurements that fall below our system noise floor are reported as the noise floor measurement.
  • bob4432 - Thursday, April 5, 2007 - link

    i would say my bedroom at night is more around 80-100db :)
  • yacoub - Thursday, April 5, 2007 - link

    So basically this thing cools nowhere near as effectively as an Ultra 120 (judging by your charts that show it a good 10 degrees Celcius hotter than the Ultra 120 at given points.

    Also, what would really make these hsf reviews even more helpful would be to see a nice list fitments on popular boards (a couple 680i, 650i, P965, and 975 boards you have around the labs). Give it a green, yellow, or red for fitment - Green, it fits fine and mounts easily. Yellow, it will fit but requires some frustration and/or 'editing' of the hardware (i.e. adding shims, shaving with a dremmel or similar), and Red, it simply will not fit... caps in the way or similar issues.
  • Wesley Fink - Thursday, April 5, 2007 - link

    As we said in Final Words " . . . but cooling is not in the same league as the top Tuniq and Thermalright coolers we have evaluated at AnandTech."

    The OCZ Vindicator is competetive with the better coolers when you add a higher output fan, but the cooling performance is still far below the Tuniq Tower 120 and the Thermalright Ultra 120/Ultra 120 Extreme.
  • yacoub - Thursday, April 5, 2007 - link

    Please don't miss the important part of my comment, which was not the first sentence stating the obvious, but the larger portion in bold. Thanks.
  • Wesley Fink - Thursday, April 5, 2007 - link

    I didn't miss your bold. Adding fitment info is a good suggestion.
  • poohbear - Thursday, April 5, 2007 - link

    dude, anandtech or any private site should NOT be responsible for testing product compatibility for a company, that's the company's responsibility.

    did you get my message in bold? good. unless OCZ is gonna pay sites to do this, then anantech shouldnt be doing OCZ's job for them.
  • DrMrLordX - Thursday, April 5, 2007 - link

    Who got the silentpcreview forum posters all in a tiff? The article wasn't *that* bad. It should be obvious by now that cooling performance and overclocking performance are the two main foci of these articles.

    As anyone who reads Anandtech regularly should know, Anandtech reviewers doing "sideshow" reviews with limited testing equipment/materials include whatever happens to be handy in lieu of using an extensive array of parts. Someone sent them the SilenX fan, so they used it. Big whoop.

    Pay attention to the cfm ratings and ignore the commentary on noise if you're so upset about it.

    Overall, I found the review to be "eh" because they reviewed a less-than-exciting hsf. It performed poorly without an add-on fan, and with an add-on fan, it was still beaten soundly by top-tier coolers using included fans (some with lower cfm ratings). I guess I have to ask, "why bother?".

    I'm not even entirely sure why they included the SilenX fan other than to discover if the HSF had some kind of potential to be a great balance of silence and performance, but I think we can all agree that the dual low-cfm Infinity holds that distinction.

    It IS good to know that a fan comparison is coming up. I guess that may be one reason why the SilenX fan made it into this review . . . we should expect to see it later in the fan review.
  • Chunga29 - Thursday, April 5, 2007 - link

    My thoughts exactly, for the most part. SPCR has its own niche and this is not the same market. So the noise level is higher than anyone at SPCR would allow? Big deal. I also don't recall reading anything where they stated that the specs of the fan, HSF, etc. were 100% truthful. They just used a fan that almost certainly had a noticeably higher air movement potential, and the testing bears this fact out. For a real-world test case (which SPCR doesn't do) the SilenX was no louder than the original fan and improved cooling. That's somewhat useful information.

    Actually now that I think about it, I know exaclty why the SPCR guys are pissed. It's the paragraph on page 7:

    quote:

    We have also measured the Corsair 620 watt and Mushkin 650 watt power supplies which are reported to be quieter than the OCZ. Both the Corsair and Mushkin are indeed quieter at idle or start up speed. However as soon as load testing begins and the PSU fan speed kicks up and the measured noise level is almost exactly the same as the OCZ PowerStream 520 watt power supply. In keeping with our "real world" philosophy of noise, we consider the PSU load noise to be the more realistic noise level of power supplies. We do plan to evaluate additional power supplies and configurations in our upcoming 120mm fan roundup, but we will tilt to real world rather than procedures that test fans on foam blocks or hard drive noise with their "noisy" side pointed toward a foam block.


    Looks like someone ruffled the feathers of the "more knowledgeable than thou" silent PC people. You read their testing and it really is quite silly at times. They basically test each part in near total isolation. I can attest to the fact that a "quiet" fan sitting in the open and suspended on foam is not nearly as loud as the same fan in a case. I'm a bit curious as to why the HSF testing environment is so loud, relatively speaking (only 36.4 dB minimum with everything off!?), but at least the results are consistent.
  • Spoelie - Thursday, April 5, 2007 - link

    You're actually using flawed logic there. How much of the time is your cpu under heavy load? How much of the time has your psu kicked up the pace? The idle and mid load levels are a lot more active and make up the majority of the time of almost any desktop computer. Consider the following for a real world scenario...

    The corsair and seasonic do not kick up their fans till they provide about 250-300w. This load level will only be achieved when both the vidcard and cpu are under load, a cpu alone will not reach that load level. Now the only case in which both the heavy consumers are under load is gaming, at which point we do not really care about noise levels anymore, since the gaming sound effects will drown out any noisy fan.

    However, if we're working in windows, either lightly loaded (browsing, ...) or heavily loaded (encoding a something to h.264, ...) we're much more easily irritated by a noisy computer. The good thing about the other psu's is that in those scenarios, they will be at their base noise floor, and virtually silent, certainly quieter than the OCZ. So at that point we can objectively measure the difference between the fan configurations.

    So in essence, PURELY REGARDING NOISE LEVELS, spcr has a more realistic sound measuring system. I do know however that this is not the focus of this article, so it's kinda silly trying to defend the article on these points. Read the article for the overclocking and temperature levels, that's what it's good for.
  • Wesley Fink - Thursday, April 5, 2007 - link

    You make a good point, but I remain concerned about introducing additional noise and cooling variables into the test platform with a variable fan speed PS. In flat out gaming every PS I have seen is running at load conditions. However, your suggestions are certainly "real world" and we will definitley evaluate the impact of one of the "silent idle" power supplies on our total cooler testing. Our goal is to find ways to lower the ambient noise and sytem noise floor in realistic ways to provide a wider db test range
  • yacoub - Thursday, April 5, 2007 - link

    Yeah exactly. My PC DOESN'T sit at Load settings for its fans. See I actually have them all dynamically controlled by temp and they only spin up when the machine is actually processing heavily enough to warm things up to a level that needs the fans to spin up a bit more to cool effectively.

    I'm starting to think it's more a matter that most folks don't care enough to quiet their PCs down so they don't realize how much nicer it is to have a quiet PC. This would be why they think it's normal to have a PSU making 40db of noise and thus fans can be 36db of noise and they think that's ok.

    My PC (and it's not exactly designed to be totally silent) is inaudible except when I'm gaming or doing heavy work in a program in windows that requires the cpu to load up a lot. I can surf the Internet, type a Word doc, listen to music, or watch a DVD, and it's inaudible unless you put your ear within a foot or two of the case.

    (P150 Antec case, Antec True-Power2.0 450w PSU (recently replaced by a Corsair 520w that has a fan that is a tiny bit more audible), SpeedFan, ATiTool, and good configurations are to thank for that. It's even using the retail cooler on my A64 Venice 3200+ and it's overclocked to 2.4GHz and it's still silent because I have the fan on it throttle down to 40% when it's under 40C, which it is most of the time.)
  • punko - Thursday, April 5, 2007 - link

    For me, my wife watches television in the same room that I have the computer. When I'm gaming I use either very low sound or headphones.

    Noise is an issue, whether at idle, low load, or heavy load.

    If anything, I tend to have the CPU and GPU maxed out when I'm on the computer, so the "real world" testing of a complete system underload is the most important sound rating. Idle? don't care, that means I'm not in the room.

    What I would love to see is a general guide for those of us planning to build a new rig, and get an idea of what is available in terms of major components for building a quiet (not silent) PC. I am more than well aware that there are specialist sites that do component by component reviews, but I am more interested in the "real world" knowledge of people that assemble and use hundreds of components in various configurations.

    Articles like this one help, because the focus the attention on a particular component as part of an overall system.
  • yacoub - Thursday, April 5, 2007 - link

    oh and by "only spin up" i mean "spin up from the level I have them throttled down to" not "spin up from stopped". You never want to throttle fans down to where they stop while the system is on, because there's always the danger they won't spin back up.
  • asdfqwertyuiop - Thursday, April 5, 2007 - link

    This article is poor. The SilenX claims are just false, and parroting their marketing BS without adequate testing is unsatisifactory. There are about a dozen fans, including the stock Intel one, all on the same db rating. So in other words, testing was insufficient to establish whether or not the fans are quieter than even the bog-standard Intel one.

    Accepting SilenX's BS that their fan achieves dramatically more airflow with less noise than anything else available shows excessive credulity.

    Aside, what's with tech firms and the product names that sound like they are aimed at 13-year olds? Vindicator??? This is a heatsink, not an assault weapon.
  • tomoyo - Thursday, April 5, 2007 - link

    As stated by quotes from a silentpcreview reader here - http://www.silentpcreview.com/forums/viewtopic.php...">http://www.silentpcreview.com/forums/viewtopic.php...

    There's so many inaccurate and incorrect commentary in this review that it's utterly amazing it was ever posted. It's obvious the heatsink was designed by scythe and relabeled by OCZ, that's nothing terrible to say since tons of brand names are made by different companies. I'm MOST disgusted by the blatant love of Silenx fans when their specifications on their fans are 100% WRONG. It is physically impossible for their fans to be as quiet as they say, which means they're purely and utterly liars. A company that lies should not be praised like anandtech is doing. I'm surprised they are not using a quiet nmb-panaflo, nexus, or other good fan out there.
    And the OCZ powerstream is certainly not one of the quieter power supplies out there. A better comparison psu would be something like a Seasonic or Corsair.
    There's plenty of other issues with the writing quality here, but I think these are the most blatant.

    Silent PC Reviews are a total joke. They in no way simulate conditions inside, near, or even remotely in plain sight of a PC. Most of the members over there are elitist wannabes who drink the Chin Kool-Aid and then march off like ants to spread the gospel of lies that are the SPCR test results. Most of their articles are contradictory once you really read them and the computer equipment they use is several generations old. They are not even using equipment that most of us have bought in the last two years and to even consider a P4 and 6800GT as components that stress a power supply is just laughable. The site is one big cluster "F" with most of the recommendations going to their sponsor list. I could not believe some of the asinine comments posted in that topic. Hopefully they wake up and smell the $h!t that is spewing from the writers over there.

    My issues with the cooling reviews here are the noise levels in the room. They really need to be around 26 to 30dBA to properly test most components in your "real world" test routines. There are a lot of people who probably have rooms at home in that noise range along with components whose base noise levels fall in the same category. I would also like to see how well the units fit on the top three or four selling motherboards along with some power supply reviews.
  • Wesley Fink - Thursday, April 5, 2007 - link

    According to a Noise article at SPCR 26 to 30db is the noise level of a "quiet bedroom at night". 35 to 45 db - our ambient noise is 36db - is the noise level of a "Quiet office or library; Typical PC Subdued". The complete chart is in comments below. We hope to lower noise a bit in a reworked test bed but we are not confident we can get below 30db consisitently.
  • Chunga29 - Thursday, April 5, 2007 - link

    I have to wonder if part of the issue might be your sound meter. Some meters are only good to measure levels down to ~35 dB. I've played with a sound meter at work (the HR department had to conduct "ergonomics testing" [rolls eyes], and as the IT guy I had to make sure the PCs weren't "too loud". Not sure what we were supposed to do if the Dell systems made too much noise for comfort, though....) Our offices were at a pretty consistent 45-50 dB during the day. Even a normal conversation would jack that level up to 55-65 dB (depending on the speaker(s).

    At night with all the computers shut down, however, the noise level dropped below 30 dB and our meter was no longer useful as far as I could tell. Of coruse, at that point even moderate breathing in the vicinity of the meter would increase the detected noise level, as would walking. In my experience, then, 30 dB is basically extremely quiet (even "silent"), and anything lower than that is not likely to be meaningful unless you are testing in some soundproof location.

    I would think in a standard house with all of the noise generating equipment (fans, refrigerators, heat/AC, TV, etc.) shut down that reaching 25 dB should not present a problem. Whether your equipment can reliably measure noise levels at that point is the real question.
  • Wesley Fink - Thursday, April 5, 2007 - link

    CORRECTED - Editors would also like to be able to edit their comments :)

    It seems that every cooler or hard drive review that we have recently posted is met with rocks from SilentPC "readers". This is really puzzling, since we have stated many times that we admire the good SPC has done in making manufacturers pay much more attention to the noise their components generate. There are many more choices of low-noise components because enthusiasts and sites like SPC have pointed out the noise offenders, and buyers have bought the quieter version instead.

    Testing component noise in isolation provides useful information, but AnandTech has a long tradition of "Real World" testing. Overclocking also has very different demands than building the quietest PC to run at stock speeds. The noise floor for any working system will be the power supply generally, and possibly the video card or ambient room noise. It doesn't matter in our approach how quiet a fan is if the power supply is 20db louder. This is pretty obvious but it is rarely mentioned when people are screaming about a fan at 14dbA versus a fan at 18dbA or hard drives that are 2db apart at 26db. Does it really matter if the power supply in the system is at 36dbA?

    We do plan to move to a quieter power supply in our test bed as soon as we can find one that meets our needs. We have looked at several of the power supplies proclaimed in comments in past reviews as "MUCH quieter than the OCZ PowerStream 520W". They were quieter at idle, but at load those power supplies were virtually the same noise level as the OCZ. Idle noise might matter if you sleep in the same room with your computer, but you can't do anything with an idling computer except look at it. We believe the normal operating noise measurements are the noise levels that matter most.

    If readers prefer the review approach of another site that is their right, but we do hope they will stop investing so much emotion in their comments. We think there is room for both the component isolation approach and the AnandTech "real world" approach. We also don't think there is any "right" or universal truth to be gleaned here - they are just different approaches.

    We chose the SilenX fan because it specified higher output than the SFlex at noise levels that were far below our system noise floor. We could just as easily have used the SFlex with a specified 63.7cfm instead of the 72cfm of the SilenX. However, since we have not yet done our fan review we didn't want to tilt sentiment too strongly to one brand name so we chose another quality product to put another deserving brand in the spotlight.

    Our plan going forward is to complete a few more waiting cooler reviews, and then select the top air cooler from our reviews. This will be followed by a fan roundup testing fans on our top performing HSF. New reviews will then be tested with stock components PLUS the top fan from our roundup. This should provide some consistent answers to some valid real-world questions.
  • Wesley Fink - Thursday, April 5, 2007 - link

    Yes, it appears SPCR had the SilenX wars recently, but the fan in this review is NOT the same one tested at SPCR. Someone needs to back away and also point out that while the SilenX fan did not match it's noise specs in the SPCR review it DID test at less than 18db, which is still exceptionally quiet. In addition a recent SPCR review of the 14DBa SilenX power supply concluded "The SilenX 14 dBA advances the state of quiet fan-cooled power supplies by another few decibels."

    The SilenX DID improve the cooling ability and the overclocking ability of the OCZ Vindicator compared to the stock fan, and it did so at measured noise levels below the noise floor of our system. These things we did confirm in our review. We did not test the claimed specifications since our concern was cooler performance, overclocking, and noise lower than our system noise floor.
  • ATWindsor - Thursday, April 5, 2007 - link

    Less than 18 dba at 10 cfm that is, at full speed it is noticably more noisy. (the SPCR-test puts it at 33 dba), I have myself measured fans, and the specs are more or less hit and miss, my conclusion was that the very best indicator of noise is the rpm of the fan. 14 dba isn't even close to realistic at stock speed. Hower also SPCRs reults are not entirely reliable at levels below 20 dba, that is very quiet for a room not specifically designed for it, and most sound-level-meters (even good ones), have a noise floor on the 15 dba-range.

    The problem is that nobody knows how these numbers are measured, 14 dba at what range? 20 meters? It like saying "this heater will give you a room-temperature of a 100 degrees F. Its more or less meaningless when you now nothing about the room, as a heater, sound should be stated as sound-power. Then you can easily calculate sound pressure level in a given room at a given distance.

    Are you going to be doing some comparisons to the value coolers?

  • Wesley Fink - Thursday, April 5, 2007 - link

    A value cooler roundup is planned for the future.
  • Bumtrinket - Thursday, April 5, 2007 - link

    I think what's got up SPCR readers' collective noses is the way you allowed SilenX's claim to pass without challenge, and presented it as established fact: "Replace the stock fan with the quiet (14 dB-A) and powerful (72 CFM) SilenX IXTREMA 120 and the Vindicator can overclock with the best." Unless there's some way SilenX have found to defy the laws of physics, there's no way a fan capable of shifting that much air could be that quiet.

    I'm not sure if you're aware of SilenX's history of deceit as regards SPCR, but that was like a red rag to a bull.

    Incidentally, you state that the Scythe Ninja needs a mounting bracket for use with Socket 775 mobo's - that's not true, as it's used the standard Intel pushpin method since revision B was launched several months ago. I'm a bit surprised you consider this would be "good news," especially in a heatsink of this size and weight.
  • Wesley Fink - Thursday, April 5, 2007 - link

    Easy mounting is always good news, but there are valid concerns about the huge weight being supported by something as flimsy as pins. That concern is also stated in the review.

    I have the Ninja Plus Rev. B in for review and the bracket and instructions for the AMD AM2/754/939/940 is NOT a push pin install. For AMD the bracket attaches and clips onto the center pin of the AMD mounting cage - which is supported by screws and a back plate. You still do not need to remove the board or the "cage" to install the Nija Plus Rev. B on an AMD board. THe bracket for Intel 775 IS push pin, but it is the only push pin solution.
  • Bumtrinket - Thursday, April 5, 2007 - link

    ermm... OK, but I was referring specifically to socket 775, not AMD. It's hardly worth arguing about, but you might want to correct what you actually said: "The good news is the OCZ Vindicator comes preconfigured for Intel Socket T, where the Scythe requires installation of a bracket before it can be used on that socket. Mounting socket plates on both coolers is basically the same."

    I was rather hoping there would be a bolt-thru plus backplate solution for socket 775, which would have avoided the main gripe with the Ninja, but it seems it's not to be.

    It seems that every cooler or hard drive review that we have recently posted is met with rocks from SilentPC "readers". This is really puzzling, since we have stated many times that we admire the good SPC has done in making manufacturers pay much more attention to the noise their components generate. There are many more choises of low-noise components because sites enthusiasts and sites like SPC have pointed out the noise offenders, and buyers have bought the quieter version instead.

    Testing component noise in isolation provides useful information, but AnandTech has a long tradition of "Real World" testing. Overclocking also has very different demands than building the quietest PC to run at stock speeds. The noise floor for any working system will be the power supply generally, and possibly the video card or ambient room noise. It doesn't matter in our approach how quiet a fan is if the power supply is 20db louder. This is pretty obvious but it is rarely mentioned when people are screaming about a fan at 14dbA versus a fan at 18dbA or power supplies that are 2db apart at 26db. Does it really matter if the power supply in the system is at 36dbA?

    We do plan to move to a quieter power supply in our test bed as soon as we can find one that meets our needs. We have looked at several of the power supplies proclaimed in comments in past reviews as "MUCH quieter than the OCZ PowerStream 520W". They were quieter at idle, but at load those power supplies were virtually the same noise level as the OCZ. Idle noise might matter if you sleep in the same room with your computer, but you can't do anything with an idling computer except look at it. We believe the normal operating noise measurements are the noise levels that matter most.

    If readers prefer the review approach of another site that is their right, but we do hope they will stop investing so much emotion in thier comments. We think there is room for both the component isolation approach and the AnandTech "real world" approach. We also don't think there is any "right" or universal truth to be gleaned here - they are just different approaches.

    We chose the SilenX fan because it specified higher output than the SFlex at noise levels that were far below our system noise floor. We could just as easily have used the SFlex with a specified 63.7cfm instead of the 72cfm of the SilenX. However, since we have not yet done our fan review we didn't want to tilt sentiment too strongly to one brand name so we chose another quality product to put another deserving brand in the spotlight.

    Our plan going forward is to complete a few more waiting cooler reviews, and then select the top air cooler from our reviews. This will be followed by a fan roundup testing fans on our top performing HSF. New reviews will then be tested with stock components PLUS the top fan from our roundup. This should provide some consistent answers to some valid real-world questions.

    I would also like to know a more quantifiable difference between the stock fan and this silenx fan. The noise measurements are kinda useless since they put everything on the same level. But do they actually sound all the same? Is the silenx really quiter?? Would be kinda strange.

    So even if it is like (this one sounds louder as that one, and when i put my hand before them i can feel more air move with this one than with this one) than we can at least confirm what each fan does, just not by how much. The only thing we know at this moment is that the silenx moves more air, judging by the temperatures.

    silentpcreview is really good, but the focus on these articles is different, they're more geared to overclocking. So while some critique is valid, this article is not trying to be a definite one on the noise front or a competitor to what silentpcreview does.
