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.
As the Sapphire R7 250 Ultimate is a fan-less solution, we had to stress the card for a long time to see how the cooler handled with continued heat from the core. It peaked at 67c when gaming, and 75C when under Furmark load. These are good results.
