Sapphire R9 290X Vapor-X OC 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.

The Vapor-X is extremely impressive – holding gaming load temperatures around 64c in our specific environment. Sapphire always take the top positions in this test, so we can't say we are surprised.

Sapphire have went to town with the cooling on the R9 290X Vapor-X OC PCB, as we detailed earlier in the review. This has a positive effect on VRM temperatures which peak at 60c and 63c after 10 minutes of Furmark stress testing. These temperatures are actually a few degrees lower when playing games, as Furmark places a ‘worst case' scenario load on a graphics card.
