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.
Sapphire prove just how good their cooler designs are – taking the top positions in the graph, along with the excellent Jetstream cooler on the GTX780 Ti. The cards are 32c cooler than AMD's reference design under load !
The VRM's seem to be running very cool too, around 60-62c when gaming, and between 67-68c under synthetic Furmark load.
