Thermaltake Big Typhoon VX: Does VX Rule Cooling?

Cooling at Stock Speed
Some users will never overclock their CPU, but they still want to run the coolest CPU temperatures possible to enhance stability and extend CPU life. The Thermaltake Big Typhoon VX comes complete with a variable-speed high-output fan. Therefore we tested the VX cooler with the supplied fan at its maximum speed for the performance results.
Where the very good Intel stock cooler keeps the X6800 at 41C at idle, the VX managed 27C, which is outstanding performance. This is a significant improvement over the Intel stock cooler performance, and results are just 1C short of the best we have tested. The Thermalright coolers, at the top of our heatpipe tower performance charts, cool to 26C and 27C, and the Tuniq 120 maintains 27C. The Big Typhoon VX is very competitive in cooling at stock speed idle.
It is more difficult to effectively simulate a computer being stressed by all of the conditions it might be exposed to in different operating environments. For most home users CPU power is most taxed with contemporary gaming. Therefore our stress test simulates running a demanding contemporary game. The Far Cry River demo is looped for 30 minutes and the CPU temperature is captured at 4 second intervals with the NVIDIA monitor "logging" option. The highest temperature during the load test is then reported. Momentary spikes are ignored, as we report a sustained high-level temp that you would expect to find in this recording configuration. This test configuration roughly equates to an 80% CPU load test using Intel TAT.
Cooling efficiency of the Thermaltake Big Typhoon VX was then compared under load conditions at stock speed to the retail HSF and other recently tested CPU coolers.
The VX under load at stock speeds reached a maximum temperature of 38C with the included fan at its highest speed. This compares to the Thermalright coolers at 32C and 33C, the Tuniq at 34C and the Cooler Master Hyper 6+ and Zalman 9700 at 36C. Stock load performance is average to above average among tested coolers, which was something of a disappointment after the excellent stock idle results.

I notice on your photos that you've mounted the VX120 such that the heatpipes are working maximally against gravity for the condensate inside to return to the evaporation point on top of the CPU. I can't say I'm thoroughly versed in heatpipe design, but it is generally best to have them oriented such that the condensate capillary-action return is not fighting against gravity. In fact, if you mount the VX120 correctly, three of the six heatpipes will experience gravitational assistance in returning the condensate from the cooling fins back down to the CPU, and the other 3 heatpipes will be experiencing only a very slight negative gravitational gradient. The way Anandtech has mounted the VX120 is, in my option, incorrect for vertical motherboard mounting in a tower case.neweggster - Sunday, June 10, 2007 - link
You people complain that having this sort of HSF is like owning stock to a big company. You guys act like Anand has done you wrong in a test of a HSF that doesn't reflect what you would do, furthermore; complaining that the results are not efficient because the lack of case fans.First off who cares, second we want to buy things that are more efficient and thats why side blown HSF are better then down blowing HSF. Conclusion is that if you have to do more to get a side HSF to work efficiently then why bother?? Why argue the points that this HSF style works far better when adequate exhaust fans are used. The comparison shows little to no difference when using side case fans to get this VX working more efficiently.
I would much rather use side blown HSF and have to do less configuarations to get it to work optimaly then to use a down blowing HSF that you have to have more exhasut fans and better configurations of the case airflow.
The point is that DOWN BLOWING HSF SUCK PERIOD!! Does not matter, we see that side blown HSF work better and ideally generate less static heat around the mobo, so why argue that you can improve the down flow HSF designs to get better performance and have to do more then just using what works best.

Edit, I meant to say Down blowing on this sentence but said Side.Conclusion is that if you have to do more to get a side[/B(should be Down) HSF to work efficiently then why bother??

It seems as though that everyday some company comes up with another gimmick for the clueless. There must be a lot of suckers with more money than brains.Avalon - Friday, June 8, 2007 - link
The reviews lately on the downward blowing coolers seem to imply that we only care about cooling other system components with that airflow to increase our overclock. Not so.I like downward blowing coolers because I like my other components running cooler. They will potentially last longer, and I won't need to add on additional fans or heatsinks for each part.

The differences and performance between the 2 can be vastly different in a real world setupA PC case with a Side Door Fan which most have would greatly benefit the Down facing Heatsink since cool outside the case air is pumped through the cooler. Where in any instance the side mounted fan is gettimg all its air directly once it has passed over the already hot Sticks of Ram which had already passing over HDD cage, hardly cool air to start with
The other benefit of downfacing fans is that they cool both the base of the CPU and Mosfits that surround the CPU socket area

Of course if you already have side door fans then you have airflow over the motherboard, making the largest benefit of a down-facing fan less needed.erikpurne - Thursday, June 7, 2007 - link
I totally see the point the downwards-facing-coolers people are trying to make. All they're saying is that Anandtech's test-bed is unrealistic as it lacks a case exhaust fan that virtually everybody interested in this type of coolers would have installed.A backwards-facing tower cooler will tend to push the heated air out the back vent whether there's an exhaust fan there or not, since it's pointing directly at said vent in many case designs. It sort of doubles as a case fan. Meanwhile, a downwards-facing HSF will just keep recirculating the hot air.
On another note, how do you (Anandtech) compensate for differences in ambient temperature when testing the coolers? I didn't notice it mentioned on the testing methodology page.

It seems that what you're saying is that cooling towers are inherently superior to the downward-blowers, since with the latter you need a case fan but you don't with the towers. I can't recall any cases I've seen in recent history where the rear of the case doesn't have perforations/fan mounts, and the fact remains that blowing air down at the motherboard is a great way to create turbulence. But hey, if you have two case fans - one at the front as intake and one at the rear as exhaust - then the downward blowing HSFs are maybe competitive with the cooling towers. Except then you have three fans instead of one or two, which almost certainly makes more noise.Wes also pointed out above that testing with four coolers didn't appreciably alter the results. The testbed is consistent and appears reasonably fair. "What if you use case X with a mod so that cooler Y blows air out the side vent that just happens to match up perfectly with motherboard Z?" Well, in that case you're probably already familiar with the setup and you just want someone to give you the thumbs up. Here you go: thumbs up! Sounds like a great setup for that particular case/HSF/mobo combination. A typical case+mobo seems a better idea as a testbed, however.
Personally, I have my PC located such that a wall blocks the left side, so the front and rear vents are MUCH more important and any case that has vents on the side wouldn't work well. I've seen quite a few computer desks that do the exact same thing, so I'd say more people than not will benefit from a heatpipe tower cooler over a downward blowing cooler.

Why test the most used replacement fans on the market, the Arctic Cooler Freezer 7 Pro and 64 Pro.They may not be the best cooling but they are under $20 delivered and are virtually silent.
Arguably the best bang for the buck
