In order to test the efficiency of the VGA cooler we installed this cooler on a reference HD 7970 and ran some tests.We gathered idle temperatures by leaving the system on the desktop in an idle state for 15 minutes, we then collect the idle temperature using either GPU-Z or CPUID HW Monitor. For load temperatures we put the Unigine Heaven DirectX 11 benchmark on for a few runs through and then took the maximum temperature for the period as recorded by our previously mentioned diagnostic programs.
Using Unigine Heaven is a more realistic way of collecting gaming load temperatures as opposed to FurMark which doesn’t replicate a real-world scenario. To account for differences in ambient temperatures we use delta temperature figures.
To get the acoustic performance of the VGA cooler we used a decibel meter held 50 centimetres away from the fans and took a reading when the HD 7970 was in an idle state and when the HD 7970 was under load.The same tests were performed on the stock HD 7970 cooler so that we have some point of comparison, it also makes sense to compare it to the stock cooler as this is the cooler most people will want and need to upgrade from.
