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.
Noise levels are traditionally a strong area for Sapphire's graphics cards and that is true here. We saw fan speeds of just 25%, or 1180rpm, during our testing, resulting in whisper-quiet noise levels of just 33dBa. I didn't notice any coil whine either throughout my testing.
