CoolIT Freezone CPU Cooler

by Greg King on November 6, 2006 in Cooling

With the growth of CPUs, more cores mean more heat. We are constantly interested in new ways to keep our processors cool and the CoolIT Freezone appears to be just that, a new approach to keeping your CPU cool. Does it deliver?

Page 4 – Testing, Conclusion

To test the Freezone, I will run the unit on with the rheostat turned all the way up, as well as on the lowest settings available. The temps will be recorded at idle as well as under full load.

The test system is:

  • Intel Core 2 Duo E6600
  • DFI Infinity 975 X/G
  • Kingston RAM Hyper X 6400 2GB
  • Enermax Galaxy 850W

To test the E6600 and get it up to load, I will run 2 instances of CPU Burn-In as well as factor Pi to 32M places using Super Pi.

    Low Power and Speed

  • Idle: 36°C
  • Load: 47°C
    High Power and Speed

  • Idle: 13°C
  • Load: 22°C


The results speak for themselves. While the results for the Freezone when set to low weren’t really any better than a stock cooler, the system as a whole was silent. When the Freezone was set to hi, the results were incredibly different. The system noise was high, but the results more than made up for it. The temps recorded were only averages of what I was experiencing. I saw my temps on high actually dip to 10’C. The installation of the Freezone was problem free aside from the mounting bracket problem and while this is something that has to be changed, this did not change the results of the Freezone’s performance.

The lack of a reservoir is convenient but also allows the water to heat up a bit quicker than it would have with the use of one. Again, the results confirm that on hi, the Freezone really doesn’t need a radiator but it’s on low where CoolIT needs to focus their attention for the next product they come out with. The silent operations of the Freezone more than makes up for the higher temperatures and if you are not going to overclock your system, the low setting should be more than enough to keep your temperatures in check.

When all is said and done, I am left very impressed with the CoolIT Freezone. The unit is made of top shelf components and the finished product is clean and looks great. With a street price at the moment of $350 (US), the Freezone might not be in everyone’s interest but if you can afford it, this is something that everyone should have. It’s just that good.

I am happy to award the CoolIT Freezone a very solid 9 out of 10 as well as an Editor’s Choice award. The Freezone will not be leaving this case for a long time. It’s just that good.


  • Excellent cooling when set on high
  • Easy installation
  • Compact size
  • Silent when on low
  • Top quality build

  • Expensive for most
  • Fan needs ‘modded’ in order to mount the converter bracket
  • Difference between hi and low temperatures is no good at all
