Performance

For comparison, we are going to use our Vantec CCK-6035. With the popularity of the Vantec CCK, it makes an excellent comparison heatsink to give you some perspective on our test results.

Now our cursory statement…

No two systems will perform identically, or for that matter, there will be variations within a single system to some degree depending on several factors. Hence our results may end up being a little better or a little worse than the results you may get in your own box.

All measurements were obtained by a thermal probe mounted on the top of the silicon of the chip so that the probe tip touches the CPU core. Our load temperatures were attained by running the CPU stability tester program for thirty minutes. The reported results are the average of three runs per product. Arctic Silver thermal goop was used as our interface material in all tests. Ambient room temperature was 74.8 degrees Fahrenheit and at no time did this base temperature deviate more than 0.5 degrees F.
