April 24, 20224 yr I setup my server with two GPUs - an AMD RX570 in a x16 slot and a Nvidia Quadro P400 in a x4 slot. This is on a Ryzen 1600X CPU with Gigabyte AB350M Gaming 3 Motherboard. The problem I want to solve is that the fan on the RX570 is always running at a fairly high RPM and generating a lot of noise. This GPU doesn't need to be used, and is only for when I boot my VMs. I figured I could manually set curves using the /sys/class/drm/card*/device/hwmon/ The problem is that there is no hwmon property and only one card (card0) shows in the drm directory. I assume this is the Quadro, as one of the directories is the PCI address for that device. I believe this issue is related to the fact that the AMD GPU is not appearing in the GPU Statistics plugin. I have installed the Radeon TOP plugin too. Help to set the fan speed would be massively appreciated (and I assume getting the AMD GPU to show up in statistics would be involved). Thanks! bossam-diagnostics-20220424-2032.zip Edited April 24, 20224 yr by polygon Uploading diagnostics
April 24, 20224 yr Solution I think you have two conflicting requirements here? If you have the GP’u isolated so that it can be passed through to a VM then it is not visible at the Unraid level and needs to be controlled from within the VM.
April 24, 20224 yr Author I’ve spent a week trying to work this out and now I feel like an idiot. I just setup radeon-profile and am now able to control my fan speed through the VM which seems to persist once the VM is shut down. Thank you very much!
