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.
With three cards in the system, the temperatures rise by 3-5 c under load as the fans on each card spin higher to try and combat the rising ambient temperatures. The reference cooler struggles to remove the heat produced by three cards in Crossfire.
