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 Metro Exodus Enhanced Edition for 30 minutes.

I was a bit surprised to hear the levels of noise that I did from the OC BIOS, with the fans spinning up to about 1970rpm out of the box, hitting 41dBa on our sound meter. Thankfully the Silent BIOS is much more relaxed, with a fan speed of around 1660rpm, producing 37dBa of noise, and I can also report no coil while was audible during my testing.
