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 talking about noise levels where we actually run into some difficulty. That's because my testing environment has a noise floor of 32dBa, so we can't accurately measure the noise of anything below that figure – and you guessed it, both Quiet and Performance BIOS did not register above 32dBa in my testing. We saw the Performance BIOS run the fans at 980rpm, while the Quiet mode reduces that to just 650rpm. That's such a low speed I am convinced you wouldn't be able to hear the graphics card at all in a case with the side panel installed, and even with the side panel removed, I had to press my ear right up against the card itself to hear it. In other words, this is about as close to silent as we can get without going completely fanless.
