Disable Zero RPM on RX 7900 xtx on Linux (lemmy.world)

Hi all!

I have an RX 7900 xtx AMD graphics card and by default it is enabled. In windows it is easy enough to disable through the adrenaline software but there is no such thing on Linux.

So far I've tried with both corectrl (1.3.11) and lact (0.5.4) and with lact i have been able to edit the fan curve but that only takes effect after the threshold of the zero rpm, which is annoying.

If it's of any help, my model is the sapphire vapor-X.

Thanks in advanced!!

i think radeon-profile could do that

Seems to have the same issues as the other software. After digging for a while seems that AMD changed the way their driver works for RDN3 cards and the zero rpm “feature” is not exposed yet to the kernel. There are some issues tracking progress but as far as i can tell AMD isn’t prioritizing the issue so who knows when this will be fixed…

In one of the gh issues someone fixed it by bypassing the vrm connector directly to the motherboard. In their model it was doable without having to disassemble anything. I don’t feel comfortable doing that so for now the only thing to do is wait…

Thanks anyways though!!

Oh yeah, sucks to hear that. I really don't know enough about how fan control works to help you further, but I wish you the best of luck to fix it further. It was worth a try, ig
