We will be testing the Freezer XTREME on a Phenom X4 9600 Black Edition, and for uniform comparison, we will be removing the pre-applied thermal paste, and applying thermal paste in the same fashion we have with the other coolers we have tested.
For idle testing, we booted up the system, allowed the CPU to stabilized at below 2% usage, and then tested for 10 minutes, and we used PCWizard and CPU-Z to record the CPU temperatures.
For our load tests, we used Prime95 to stress the CPU to 100%, and let it run that way for one hour, and then use PCWizard and CPU-Z to record the temperatures.
The Phenom X4 9600 BE is a very power-hungry, heat-intensive CPU, and to only have a 10°C increase under 100 percent load is very good! The cooler is very quiet for its performance level, and although we are having trouble with holding a stable OC on our AMD test machine, during the testing we were able to perform before instability, the temperatures only increased very moderately, and you should be able to pull a very good overclock with safe temperatures with the Freezer XTREME. Our instability is a hardware issue, and when we get that sorted out, we will update this with its overclocking performance.
