Sapphire RX 7900 XTX 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.

To produce 40dBa of noise, we increased fan speed to 48%, or about 1950rpm. This saw the Nitro+ run comfortably cooler than the reference design, offering a 7C reduction in terms of GPU thermals but a 12C reduction when looking at the hot spot temperature. This is also while operating at a higher power limit too, as noise-normalised thermals don't take power into account, making the design even more impressive.
