It takes just one look at the Arctic Cooling Freezer64 to realize it is not a standard heatsink. Arctic Cooling uses heat pipe technology able to transfer up to 200 watts to 40 fins. The patented fan holder is said to almost eliminate the “buzzing” sound commonly experienced with 80mm. box fans. The Freezer64 boasts a C/W nearly twice that of the retail Athlon 64 box cooler.

ADP Mods.com boxed up and sent the Arctic Cooling Freezer64 to the Short-Media labs for testing and the results are in.

The Freezer64 is different and it takes just one look at the fan to come to that conclusion.


The fan holder suspends the fan beside the cooler to direct air across the 40 horizontally orientated fins.


The fan holder is held in place by two screws on each arm.


Innovation has its drawbacks. It’s a proprietary design and If the fan should ever fail only Arctic-Cooling can supply a replacement if the retailer cannot. Note that the Arctic Cooling website warranties the fan for a 6-year period.



The two heat pipe posts form a “U” through the 40 fins.



The Freezer64 comes with a Socket 754-939-940 motherboard mount as well as a tube of MX-1 thermal paste.


The Arctic MX-1 paste hardens during the first 200 hours allegedly increasing performance over the same time period.


The spring clip is more of a tension bar than “springy” clip. The tension lever makes installation easy but once on the heatsink will be held firmly in place.



The heatsink base is not “mirror” finish. It has a extremely slight brushed texture to it.



The heatpipes are actually sandwiched between two layers of the heatsink base.


Noise – Sones and Phons

Arctic Cooling chooses to use the SONE measurement instead of the Decibel measurement system to rate their heatsinks. A SONE is a unit to describe the comparative LOUDNESS between two (or more) sounds. One sone has been arbitrarily fixed at 40 PHONs at any frequency, i.e. at any point along the 40 phon curve on the graph. (see following chart)

Sone: A unit of loudness . A simple tone of frequency 1000 cycles per second, 40 decibels above a listener’s threshold , produces a loudness of 1 sone. The loudness of any sound that is judged by the listener to be n times that of the 1-sone tone is n sones. A millisone is equal to 0.001 sone. The loudness scale is a relation between loudness and level above threshold for a particular listener. In presenting data relating loudness in sones to sound pressure level, or in averaging the loudness scales of several listeners, the thresholds (measured or assumed) should be specified.

The unit of loudness level of sound, numerically equal to the sound pressure level in decibels, relative to 0.0002 mircobar, of a simple 1000 cycle per second tone judged by listeners to be equivalent in loudness.

Decibel ratings are more common but calculated differently but most use the A-Weighted scale (a filter that compensates for the non-flat frequency response of human hearing, in order to get numbers approximating human response.) The following chart shows how sound “loudness” changes over frequency comparing phons, sones and decibels. At a 1khz cycle phons are the same as decibels.


Sones and Phons aren’t quite the same as decibels. Most decibel specifications are given using the A-Weighted scale. A sone The following chart compares the Socket 754/939/940 Arctic Cooling heatsinks. The corresponding INTEL models are the same.

The Freezer64 sits in the middle of the pack of the Arctic Cooling heatsinks but is bested in both CFM and dBA noise level by the Thermalright products. However, the Freezer64 is approximately half the price of the XP-120 (with fan) and one third less than the XP-90 (with fan).


As was mentioned earlier in the article, the Arctic Cooling Freezer64 is different. One look will tell and one look at the heatsink coverage was a surprise.


There was a little apprehension about the “exposure” of a portion of the Socket 939 processor. The traditional heatink covers 100% of the processor instead of 95%. Nevertheless installation was, more or less, the same as most other Socket 754-939-940 style heatsinks. The heasink must have the fan at the “bottom” of the case near to the video card. Those video cards with user-modified RAM heatsinks may have a clearance issue.


The fact that the retention clip lever is between the PSU and heatsink presents a tight space for large hands but not impossibly difficult.



The height of the heatsink is within a centimetre of an ATI 9800 PRO video card PCB so there are no height issues in a mid-tower case.



Test System

  • MSI K8T Neo2 MS-670E2 motherboard
  • AMD 4000+ Processor
  • 2 x 512 MB Corsair CM512-3200XL TwinX Memory
  • 120 GB Seagate HDD
  • ATI 9800 PRO 256Mb video card Catalyst 4.9 drivers
  • WinXP PRO SP2 updated
  • Syncmaster 950P 1024×768 @ 75 Hz

Testing was conducted in a LIAN LI PC67 mid-tower case with only the PSU and heatsink fan operational. The system sat operationally idle for 1 hour prior to running CPU Burn-In 25 consecutive times (Only arithmetic and multi-media ticked). Motherboard Monitor recorded CPU temperature results.

The Arctic Cooling Freezer64 is a unique design that is the strong silent type. The fan design eliminates most audible fan blade noise thus giving the listener the impression that the heatsink is quiet. It, in fact, is quiet. It produces less noise than a box fan that is similar or even slightly greater in CFM and RPM.

That is the strong selling point of the Freezer64. It also is more affordable than the heavyweight competition.



The test results reveal that the Freezer64 does not quite measure up to the full meaning of its name. There’s a large “but” attached to this. First…a reminder that the Freezer64 is extremely quiet. The unique design of the fan reduces noise levels even more but the fan only generates 32 CFM of airflow. That puts it right on par with coolers like the Gigabyte Rocket PRO and SE on low setting. The AMD supplied heatsinks in the tests move upwards of 45+ CFM of air and are comparatively much louder.

There were no system anomalies during testing or an hour or two of game play (Half-Life 2). It’s obvious that this is not an overclocker’s heatsink. The Freezer64 for the user who likes the sound of silence.

The Arctic Cooling Freezer64 sits in the middle of the pack for price and is available from ADP Mods for under $40 Canadian which is just over $30 USD.

  • Quiet
  • Easy to install
  • Unique design


  • Not an overclocker’s heatsink
  • May be more “flashy” with an LED add-on

Scores Breakdown
Attribute Score Comments
Design & layout 9 Unique design with the side mounted fan. May be more effective with a more powerful fan mounted closer to the fins. A higher score for a innovative approach.
Modding possibilities 7.5 Could be modded with an LED under the top cowling by running a wire adjacent to the fan wire.
Overclocking features 6 Not an overclocker’s heatsink
Performance & stability 7 Sufficient default peformance matching competitors lower RPM heatsinks. Does not perform well against some heatsinks with higher RPM (noisier) fans. During tests there were no system problems.
Price / value 8 Approximately $33 USD or $39.95 CAD. It’s good value in a low (almost no) noise heatsink but not if you goal is high performance cooling.
Total score 37.5/50 75%

    Well I really have an appreciation for the cooler whereas had I just looked at it from a performance side of view I would have thought it was teh crap! ;D
    I can appreciate a quiet cooler objectively now thanks! :thumbsup:

    I imagine that when toledo appears in what ...2q05? This sink may get to live up to it's name. Dual cores from what I've read run cooler! I may be mistaken as I've been known to be at times! :bawling:

    thanks guy ...you're appreciated here!

    ps:\ did I mention that I think kf deserves a promotion? :scratch:
  4. jon why is it Not an overclocker's heatsink ?

    Geeky1 Maybe you missed the temperature testing results...
    http://www.short-media.com/review.php?r=280&p=3 (bottom of the page)

    55*C under load with a stock 4000+ is wholly unacceptable for a heatsink that's intended for overclocking.
  6. Hawk
    Hawk Nice review MM. Hope you don't mind, I posted it @ IC front page news (reviews).
    I thought it was definitely a worthy review for posting friend. Well Done.
  7. Unregistered I just installed one last night in my system, ordered from sidewinder.com. I originally ordered one from NewEgg but that arrived with a broken fan (!!) and I returned it for repair, they were out of stock so they gave me a full refund and I looked around for other sources.

    Anyway, my CPU is now 5-8 degrees cooler than it was with the stock AMD cooler, and this cooler itself is certainly quiet. But as you can see from the photos in this review, it blows straight onto the power supply and as a result, my power supply fan is now spinning faster (and louder) than it was before. This is for a 3000+ Winchester on an Asus A8V mobo mounted inside an Antec Sonata case. There's also 4 hard drives mounted, and I have a second 120mm fan mounted inside as well. My ambient room temp is 18.3C, LM sensors reports 27C M/B and 31C CPU at idle. The cooler is running at default speed, LM sensors reports 2343RPM. The rear case fan is at 1205RPM and the front case fan is 1140RPM.

    The orientation is pretty unfortunate, too bad they couldn't have come up with a mounting orientation that blows to the rear of the case instead of up or down, then it would be exhausting heat toward my rear case fan (which is obviously not working very hard) and leave the poor power supply alone.

  8. nicklogan
    nicklogan Anyone know if two of these would fit in the MSI K8T Master2 motherboard?
  9. Unregistered I'm seeing easily a 5-8 degree drop on the stock AMD cooler too, and even my chipset temp seems better than before.
    I think your problems lies with poor installation (either too thick a layer of thermal paste, or you have air pockets). Having the PSU so close wouldn't help either, so maybe this cooler should only be recommended for cases where the PSU is out of the way. I have the Arctic Cooling Silentium T2 case, and believe it or not, the PSU is well out of the way (as if by design) ;)

    Most of the other reviews on the net also show that it is significantly better than the stock AMD cooler.
  10. lemonlime
    lemonlime As seen in the pictures , the bottom mounted PSU fan is in close proximity to the freezer64. If anything, this fact should improve the thermal disipation of the sink. That fan would be exhausting the 'warm' air blown through the fins.
  11. Unregistered That is a good point lemonlime, if that is the intake for the PSU; is that a case intake fan near the cpu though? (height.jpg) Seems to be a strange airflow in that case if it is. Either way, something has gone wrong if my system (overclocked to 2.5-2.6GHz) runs way cooler than the reviewer's test machine (which seems to agree with every other review on the cooler). My money is on incorrect installation of some kind. Very good pictures and review otherwise though.
  12. MediaMan
    My money is on incorrect installation of some kind.

    From the Arctic Cooling website installation guide for the Freezer64

    Align the Freezer in a standard ATX case in such a way that the fan blows the hot air to the back or to the top. In case you are using our Silentium PC Case, the Freezer 64 should blow the hot air to the front or to the top.

    You may have put your money down in error.

  13. Unregistered I didn't mean the orientation of the fan MediaMan, I meant a poor contact with the heatsink, poor coverage of thermal paste, etc.

    Having already fitted the thing myself I am fully aware of how it is meant to work. Hot air rises, etc, therefore, it makes sense to either suck the air to the front (then allow it to move upwards in a natural convection current), or to help it along and blow it up towards the fan exhausts at the top of the case.
  14. Unregistered Check out these reviews. They seem to agree with everyone else's finding appart from MediaMan.



    I currently get 27-28 degrees idle, 37-38 max load (24hr+ Prime95)
    (although my paste is over 200hrs old)
  15. TheLostSwede
    TheLostSwede Guest,

    I looked at that Bigbruin review...they measure the HEATSINKS temperature, not the cores. How on earth can there only be 1 degree difference between idle and load?
    Mediaman also had a much higher ambient (case temperature) which greatly affects the cpu cooling.
  16. Unregistered Very nice review!
    Btw, i have started visiting short-media.com every day due to my cooling issues :P Very cool place overall. Going to buy that cooler today.
  17. nicklogan
    nicklogan To answer my own question; yes if you use two Freezer 4's and trim the fins on the one nearest the AGP slot. Good cooling and extemely quiet - the hard drive is louder!

Howdy, Stranger!
