We take our noise measurements with the sound meter positioned 1 foot from the graphics card. I measured the sound floor to be 34 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 the 3DMark Fire Strike Ultra stress test 20 times. An idle reading comes after leaving the system on the Windows desktop for 30 minutes.
In terms of noise levels, the Gaming OC Pro is similarly excellent. It’s the quietest RTX card on our chart and comes in around 2dB quieter than the Founders Edition. It’s simply very hard to hear when it is actually working, so put this in a case and it will effectively be silent. Hats off to Gigabyte on this one.
