Sapphire RX 6600 XT Pulse Review

Dominic Moass August 11, 2021 Featured Tech Reviews, Graphics, Reviews

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 our noise-normalised testing, we had to increase the Pulse's fan speed to 56%, or 2040rpm, generating a significant amount of extra cooling power. That resulted in the GPU temperature falling by 12C compared to stock, with a 60C peak, while the hot spot also fell to 78C.

This is still a bit warmer than the Gaming OC Pro, but again we would expect that due to the size difference and level of sophistication between the coolers.
