Testing and Overclocking

Test Rig

CPU: AMD Phenom II 1090T
GPU: ASUS Reference 5870
Memory: 4GB G Skill Ripjaw 1600MHz 7-7-7-24 DDR3
Storage: Crucial C300 128GB
PSU: Cooler Master Silent Pro 850W
OS: Windows 7 Ultimate x64


To ensure the results were correct, the heatsink is mounted 3 times and idle and load tests run each time. An average of the results are shown on the results page.

For Idle testing Windows 7 was allowed to run with no programs running for 5 minutes.

For load testing I used Prime 95 Small FFT’s and temperatures were taken after 20 minutes.

The standard thermal paste, only branded as Cooler Master thermal paste, was used.

A Corsair 700D equipped with many fans was used for testing.

For comparison I used the Cooler Master Hyper TX3 and a WC setup using EK Supreme HF Block, HWLabs SR1360 radiator, Swiftech MCP 355 pump and EK 240 Advanced reservoir.

Ambient temperature was 17 degrees C.


The settings we used for our stock and overclocked tests are:

Stock – CPU @ 3200MHz Auto voltage

Overclocked – CPU @ 4000MHz 1.456v



The results of stock speeds.

The results of overclocked speeds

The results of the testing came up good. I was happy with the temperatures achieved, even when overclocked the CPU was kept well within the maximum operating temperature of the CPU. It might still be quite a ways behind the WC setup, but that was to be expected.
