Noise Levels

For many enthusiasts upgrading cooling the goal is maximum stable overclock, and they will live with the inconvenience of a louder system. For other users silence is the most important factor, and these users will forgo maximum overclocking if that increases system noise levels. Those who expect silence to be the domain of high-priced cooling solutions are in for a very pleasant surprise with both these Arctic Cooling solutions. It is unusual to see this much attention paid to noise reduction in value coolers, but the use of elastomeric bushings and low noise bearings show that Arctic Cooling takes noise reduction very seriously. Do these features work?

Level - 24\

The Arctic 7 (with PWM) and the Freezer 7 Pro turn out to be two of the quietest coolers we have tested so far in our new cooling test bed. All four test results are at the floor of our system noise, and the new test system noise floor is equivalent to a suburban bedroom at night in noise level.

Both Alpine coolers remain silent, even when pushed hard with load testing and overclocking, which increases fan speeds. It is rare to see such low noise levels on any cooling fan, but it is particularly impressive in coolers designed to sell for less than $25.

Neither of these sub-$25 coolers will really challenge the top of our overclocking performance results, but in their effective range - which is wider than you might expect - both coolers are extremely quiet. The frameless fan, low noise bearings, and elastomeric fan mounts are obviously doing their job very well.

    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 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.

    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
