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.
One area where the Palit GamingPro OC excels is out of the box noise levels. We saw the three fans spin at just 33%, which is 1250rpm, resulting in a noise reading of just 34dBa, the quietest of all three 4070 Ti Supers tested.
