Sapphire HD5770 Flex CrossfireX (3 screens) Review

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.

Both coolers are very capable with the Sapphire Flex loading to 63c when gaming and the Vapor X a few degrees lower at 61c. Under Furmark load this 2c difference increases to 4c.
