Sapphire R9 280X Toxic Edition OC 3GB Review

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.

This is an extremely impressive cooling system, holding gaming load around 64c in our specific environment. The results are very closely matched to the R9 280X Vapor X which was obviously running at a much lower clock speed.
