Sapphire RX 7800 XT Nitro+ Review

Following on from our stock thermal and acoustic testing, here we re-test the operating temperature of the GPU, but with noise levels normalised to 40dBa. This allows us to measure the efficiency of the overall cooling solution as varying noise levels as a result of more aggressive fan curves are no longer a factor.

For noise-normalised testing, I increased fan speed to 47%/1895rpm to hit 40dBa of noise. Re-running thermals with that increased fan speed saw the GPU temperature drop to 55C, with the hot spot at 82C. This isn't quite as good as the PowerColor Hellhound, which has a really impressive cooler, but it's still a huge improvement over the reference card and beats out the Gigabyte Gaming OC.
