XFX R7950 GPU-Z Information:
GPU-Z shows the R7950 using 0.950V while idle, which puts the card into a power savings mode. In this mode, the GPU is downclocked to 500MHz, and sits at 45C. This seems fairly warm for a card to be sitting at while idle.
Once the GPU is pushed, the GPU is clocked to 925MHz. Under a full load for 15 minutes, the temperature settles at 71C. Power utilization goes from 0.950V up to 1.250V, an increase of 0.30V. Maybe raising the fan speed will help with temperatures.
