CPU Cooler Round Up – Intel Quad Core Tested

Test Setup and Procedure

Cooler Round UP Test system

To test all the coolers, they were run on our Intel Core 2 Duo test platform which was then run at default and overclocked settings. As a baseline, all coolers will be compared to the stock Intel cooler. All of the temperatures were obtained by using Core Temp 0.95 after sitting at idle for 30 minutes and then again under 100% load for 30 minutes. To obtain 100% load, I ran four instances of Super Pi 32m calculation with the affinity of each set to a different core. I used two profiles to test each of the coolers and they are listed below. The room temperature was kept at a constant 72 degrees Fahrenheit (22 degrees C) for all benchmarking. All of the coolers were tested with Arctic Silver Lumiere as the thermal interface material.

The rest of the system is as follows

  • Motherboard: Intel 975XBX2
