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.
It's also great to see the GamingPro OC offering significant reductions in noise output compared to the FE card. We saw the Silent BIOS run at just 30%/1150rpm, while the Performance BIOS only increased that to 35%/1315rpm, so it was still very easy on the ears.
