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.
The Pulse is whisper quiet, too. In our testing, the fans span up to just 26%, or 1150rpm, and it barely registered on our sound meter, with noise hitting just 32dBa. I'm also pleased to confirm that there was no audible coil whine during my testing.
