Sapphire RX 7800 XT Nitro+ Review

We take our noise measurements with the sound meter positioned 1 foot from the graphics card. I measured the noise floor to be 32 dBA, thus anything above this level can be attributed to the graphics cards. The power supply is passive for the entire power output range we tested all graphics cards in, while all CPU and system fans were disabled. A reading under load comes from running Cyberpunk 2077 for 30 minutes for 30 minutes.

Noise levels are a real success story for the Nitro+. Even using the OC BIOS, we saw fan speed hit just 25%/1150rpm, barely registering at 33dBa on my sound meter. Switching to the Silent BIOS drops this further, to just 17%/810rpm, which is absurdly slow, and at that point we actually hit our ambient noise floor of 32dBa. In other words, the card ran so quietly it became impossible to accurately measure its noise levels in my test environment. There was also no audible coil whine throughout my testing.
