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.
As for noise levels, the Ventus is a quiet card, running the fans at 1735rpm in my testing, or 48%. That resulted in noise levels hitting 37dBa, so it is a touch louder than the 4060 Ti Founders Edition, but it's still very easy on the ears. There was no audible coil whine from my sample either.
