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 A Plague Tale: Requiem for 30 minutes.
The great news for ASRock is the Taichi proved whisper quiet. Funnily enough, both BIOS modes actually saw the fans hit 20%, or just 940rpm fan speed – usually the Performance mode runs a little louder, but not so here. That's still quiet enough for the Taichi to be right down the bottom of our chart, it's practically inaudible.
