Sapphire RX 580 Nitro+ Limited Edition 8GB Review

Temperatures were measured after 5 minutes of load under three scenario: Furmark, Unigine Heaven and desktop idle in sequential order with 2 minutes of downtime in between each test. GPU-Z was used to record the maximum temperature, fan profiles on GPUs were left to their default behaviour.

Delta temperatures are presented below to account for small fluctuations in room temperature, but for all the testing present in this graph the temperature ranged from 21.6 to 23.1 degrees Celsius.

Given the thermal output and noise levels of the Sapphire card, temperatures are very strong indeed. Sapphire does well to balance noise and temperatures and typical operating temperatures in the mid-70s keep the GPU well away from the boost frequency throttling zone.

Sapphire's decision to fit a backplate is well-founded. Heat is evenly spread with temperatures reaching no higher than 65 degrees Celsius. On the ASUS RX 570 that we also tested, a card that produces less heat, we observed higher PCB temperatures in the mid-70s since it equipped no backplate.
