PowerColor RX 7900 GRE Hellhound 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.

Making the out of the box thermal performance even more impressive is the fact that the Hellhound is simply incredibly quiet. My testing environment has a 32dBa noise floor, meaning the Silent BIOS was effectively inaudible, and the OC BIOS only registered at 33dBa on my sound meter. It would be basically impossible to hear the fans spinning over a typical case fan.
