Gigabyte VPower

Testing

Methodology

Testing a GPU cooler involves taking the temperature of the graphics processor while at idle, and at full load. First, the cooler is attached using the stock heatpaste and temperatures are taken of the GPU while it is in both states. We then remove the cooler and replace it, this time using Arctic Silver 5 heat paste and retake the temperatures.

For "Idle" state, we leave the pc at the desktop with no applications running. After 30 minutes the temperature is taken. For load, we ran our heaviest Crysis benchmark (set at 1600 x 1200, 6x AA and High detail on everything) for 30 minutes, and then retook the temperature.

All temperatures are in degrees C and were taken using Rivatuner’s temperature monitoring app.

The PC used to test this cooler was as follows:

For a comparison, results were also taken using a Zalman VF 900.

All testing is with the cooler plugged directly into the motherboard. No fan controllers were used except for the noise testing.
