Arctic Cooling Duo: Alpine 7 & Freezer 7 Pro Attack Value

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. We compile all temperature benchmarks with CoreTemp, a public domain utility that is quite stable with reproducible results on the Intel platform. This required retesting a cross-section of the best coolers evaluated so far at AnandTech. To better document performance in the large speed gap between 2.93 GHz and 3.73 GHz, we added the intermediate value of 3.33 GHz to all test results during the retest of the coolers.
Performance at stock idle is amazing for the Alpine 7 - a cooler that costs less than $15. The Freezer 7 Pro does slightly better, but both perform much better than you might expect at this price point. Where the very good Intel stock air-cooler keeps the X6800 at 31C at idle, the Alpine 7 reduces that to 25C and the Freezer 7 Pro is one degree lower at 24C. This compares to the top Thermalright Ultra 120 eXtreme at 24C, Corsair water-cooling at 24C, Swiftech water-cooling at 27C, and ZEROtherm Nirvana at 23C. In comparing results, please keep in mind the test results from the new cooling bed using CoreTemp are not directly comparable to earlier cooling results.
It is more difficult to simulate all the various stress conditions a computer may encounter in different operating environments. For most home users, contemporary gaming is one of the most demanding CPU (and system) applications. Therefore, our stress test simulates running a demanding contemporary game. We loop the Far Cry River demo for 30 minutes and capture the CPU temperature with CoreTemp's "logging" option. We report the highest temperature during the load test. We ignore momentary spikes and report a sustained high-level temperature that you are likely to encounter in this type of scenario. This test configuration roughly equates to an 80% CPU load test using Intel TAT, another respected program for thermal measurements.
We next compare cooling efficiency of the Arctic Cooling HSFs under load conditions at stock speed to the retail HSF and other recently retested CPU coolers.
The Freezer 7 Pro turns in an outstanding performance under load at stock speeds. CoreTemp results are 35C, which is one of the best air-cooling results tested so far at AnandTech. The Alpine 7 is also a terrific performer under load at 40C. This sub-$15 cooler is a significant improvement over the stock Intel fan, which reaches 50C under load at stock speed in our cooling test bed.
If you do not plan to push overclocking to the extreme, the Freezer 7 Pro is an outstanding choice. The stock performance at idle and load is among the best we have tested - matching or coming in a bit better than the Thermalright Ultra 120 eXtreme. The Alpine 7 is frankly cheap to buy, but it still significantly outperforms the stock Intel cooler at stock speeds. These reasonably priced coolers from Arctic Cooling are great choices if you want better cooling at standard CPU speeds.

The "photo gallery" from CES (Jan. 2008) included a photo of Arctic Cooling's "Freezer Xtreme". Any idea when that CPU cooler will be available?I have a screen capture of the photo, but can't locate it on Anandtech.com for posting the link.
It's an "8-pipe cooler that only weighs 600 grams".

"In fact, they are so good at stock performance that it is easy to recommend one of these coolers as a way to extend your CPU life even if you have no intention of overclocking."Really, has anyone ever had to extend the like of a stock cpu?
I have never even seen a stock cpu that failed due to age. They last lots longer than their useful life.

I've been using the Arctic Cooling Freezer 7 Pro for about half a year now. It's mostly quiet and cool, even with my Pentium D 830. Recently, the dust collecting in my Cooler Master Centurion 5 case has caused the CPU to overheat under 100% load(and that powered off the PC). Anyhow, I 'd definitely recommend it to anyone using a stock Intel HSF, especially for the extremely hot Pentium D's.I'm glad that AnandTech finally reviewed it. Why didn't you highlight the fact that the Freezer 7 Pro beats every other coolers tested so far at AnandTech at stock speed(at both idle and load, in both aspects of temp. and noise)?

At long last you tested the Freezer 7 Pro !!These are simply outstanding coolers for the price.
My Q6600 at 3.0GHz stays under 60C on all cores at full load per Coretemp, in total silence with fan rpm barely breaking 1,000 rpm. There is simply no need for a cooler any better for this level of CPU performance.
My QX6700 is a different story - there the Freezer 7 Pro kept the cores at a within-spec 70C but with the fan at 2,600 rpm and with associated noise. I replaced that with a Thermalright 120 Extreme, and that CPU now runs at 3.0Ghz with core temps under 60C. At least a 10 degree drop compared to the Freezer 7 Pro.
So, Freezer 7 Pro does have it's limitations, but for all but extreme overclocking, or the B3 core quads, it is all 99% of people will ever need.

I have a Freezer Pro over top of a E6750 at 3.3ghz. Runs very cool and quiet. I also have the alero on the vid card and use Artic fans to cool the case. Overall a very quiet system. The only noise I get is from the Earthwatts 380 power supply which is comparativly quiet to other PS's.Interestingly, I used the Artic Freezer on my other system with a Q6600 Quad Core running at 3.4 prior to replacing it with a Tuniq Tower! I really spent the extra $ for the tuniq for nothing! Although the temps were down by about 3C across the board, it didn't allow for any higher overclock! Plus I pick up more noise to get those lower temps!
My first experience with Artic came with the imported coolers for the original Slot A K7 CPUs and I have always been impressed with their engineering and quality. The keep a very high standard and I doubt I will venture far from them in the future as long as that continues!

You should mention in article this is also good for OC. This is the cooler most get to overclock the 1.86ghz c2d over 3ghz.Not sure why you said it was good for just stock cooling..its great for OC.

We also tested and reported overclocking on page 8, and the coolers are fine for moderate overclocking. It is just that neither cooler comes close to the top overclockers we have tested. The Alpine 7 dissipates 90W, and the Freezer 7 Pro dissipates around 130W. The top Thermalright Ultra 120 eXtreme performance shows it is dissipating around 165W. Most of the top air coolers we have tested dissipate 150W or more.Polynikes - Tuesday, January 29, 2008 - link
This is a pretty old product to be reviewing... I've had my Freezer 7 for well over a year, and I'm sure it had been around a bit before that.That said, it is by far the best bang for the buck HSF you can get. Those giant towers may cool better, but they're huge and are hard to get in even some fairly large cases, and are much more expensive.

I have the Antec 900 case with the giganto fan up top can it be mounted to blow upwards? I wonder if the freezer pro 7 would even better? Either way
