The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this.
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.
The VTX3D HD7770 runs very cool, hitting around 62c when gaming. This rises to 68c when placed under synthetic load in Furmark. Still, very impressive results for the reference cooler.
Crossfire results are quite good as author said compared gainst more expensive 7950. much like the 5770 I owned, I had two and it was really good.
