Gigabyte RTX 4070 Ti Super Aero OC 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.

Given the Aero OC offers a choice of Silent or OC BIOS, noise levels can vary slightly depending on which you choose. The Silent BIOS ran its fans at 1340pm in my testing, whereas the OC BIOS ran at 1500rpm, resulting in a 2dBa increase to noise levels.
