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 for 30 minutes.
The JetStream OC impresses with its out of the box noise levels, peaking at just 36dBa in my testing. This was with the three fans running at 37%, or just 1400rpm, putting it on par with the Gaming OC's Silent BIOS.
