Hey everyone! I recently built a new PC with an ASUS B850M-Plus Wifi motherboard, an AMD Ryzen 7 9800X3D processor, and an AMD RX9070 XT graphics card, all running KDE Plasma. I’m trying to play Cyberpunk 2077 on Steam using Proton Experimental, and I noticed that my computer fans ramp up to maximum RPM as soon as I start the game or load a save, making a ton of noise. However, when I close the game or just hang out in the menu, the fans chill out completely. I also tested it on Windows and the fans stayed quiet, and on Fedora KDE with Proton Experimental, they were quiet too. So it seems to be an Arch thing. I’ve stress-tested my setup, and the temps stay below 90°C. I’ve tried a bunch of things, including checking my drivers, trying different Linux kernels, and even setting a fan profile in the BIOS to “Silent” mode, but nothing seems to help. I’m not sure what’s causing this since everything seems fine in other setups. Any advice would be super helpful!

You might want to double-check your BIOS settings for fan profiles. Sometimes, there are specific settings on ASUS boards that don’t translate well across different OS. Have you tried just resetting your BIOS to default settings and then setting it back to ‘Silent’? That might help.
Thanks for the suggestion! I actually installed Lact on Fedora to check the GPU fan RPMs, and you were totally right. The GPU fans were spinning at around 800RPM on Fedora, while the Arch setup was 2.2k. I disabled the overclock option on Lact on Arch (forgot I had done that while troubleshooting), and now the fans are behaving properly!
I’ve had a similar experience with Cyberpunk, but it was only my GPU that was loud. Could you make sure those high RPMs are coming from the case fans and not the GPU itself? It’s easy to mix the two up, especially under load!
