Sapphire HD7790 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 Sapphire HD7790 OC runs nice and cool, peaking at around 53c when gaming in our environment. Under the synthetic stress test, this increases to 58c, still fantastic results. The dual fan cooler is handling the core temperature without a problem. This would lead to long term reliability.
