HIS HD6990 Dual CrossfireX Review

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 25c – 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 fans on both cards find it hard to deal with radiated and generated heat, moving on a fairly regular basis between 60 percent and 95 percent. When gaming, the situation isn't quite as bad, however they are clearly audible, even inside a performance gaming system with many case fans.
