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.
Likewise, noise levels are slightly higher than the Vanguard SOC, but the GamingPro OC is still very quiet overall. In practice we saw the Silent BIOS running at 32%/1205rpm, compared to 34%/1285rpm using the Performance BIOS, so both modes are actually very similar in terms of total noise output and are a big improvement over the Ventus 3X.
