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.

Noise levels are second to none for the Pulse. In fact, the fans barely spin – under load we saw them ramp up to just 34%, or 1230rpm, creating a near-silent graphics card. You simply would not be able to hear the fans spin unless you got your ear right up against the card itself, it is very impressive stuff.
