Gigabyte RTX 4080 Gaming 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 Metro Exodus Enhanced Edition for 30 minutes.

Speaking of noise, we have no complaints here either. The OC BIOS proved just as loud as the Founders Edition, hitting 38dBa on our sound meter, and the Silent BIOS improves things further by dropping fan speed by about 200rpm, reducing noise to 36dBa, which is very good going.
