Zotac RTX 3090 Ti Amp Extreme Holo Review

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.

Part of the Amp BIOS' impressive thermal performance is explained by fan noise – the three 100mm fans ramp up to 56%, or 1820rpm, and that is quite audible, even over my chassis and AIO fans. The good news is the Quiet BIOS is much easier on the ears, running the fans at 46%, or 1480rpm, matching the noise levels of the MSI Suprim X when using its Silent BIOS.
