Power, Temps, Noise

We measured power for the whole system using a Kill-a-Watt P3 meter, recording desktop idle, during playback of a high definition DIVX movie using PowerDVD 12 with hardware acceleration and enhancements, and gaming load. Our gaming load is a 10 iteration loop of 3DMark 11 GPU test 2, run at extreme settings. The highest value seen in the last run is recorded (10 runs used to get everything good and hot like a gaming session). We used CPUID's HWMonitor to record minimum and maximum GPU temperature values.

Power and Temps


HIS Radeon HD 7770 iCooler

Both cards are quiet at idle, but the reference fan becomes more noisy as load increases, faster than the iCooler version does. The scuplted blades and tweaked shroud apparently make a difference to noise level. Both designs are much better than the previous generation blower style fans and heatsink shrouds.
