Inno3D RTX 4080 iChill X3 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.

The Inno3D iChill X3 is the quietest 4080 we’ve tested, producing just 35 dBa of noise – making it quieter than the Gigabyte Gaming OC, even when using the Silent BIOS. We saw the fans spin at just 1250rpm, or 39% speed.
