## Describe the problem Zero RPM/fan stop cannot be controlled for RX 7000 series even on the very latest bleeding edge AMDGPU [kernel driver](https://gitlab.freedesktop.org/agd5f/linux/-/tree/1cff1010bef6f325d895db0306b59dc7232ed9b7) and [firmware blobs](https://gitlab.freedesktop.org/drm/firmware/-/tree/96447dfe5542b8576c32ddab07e8cf604f4d0903). It is supported in the Windows 11 Adrenalin driver package through a GUI toggle. ## Describe the new feature behavior The kernel driver and firmware should expose the necessary functionality for setting the fan spin criteria. Example: Setting a minimum RPM or % of fan speed like in the _fan_curve_ kernel interface that the GPU should always run at, or the minimum temperature in Celcius for the fans to start spinning, or just an ON/OFF toggle like Windows Adrenalin. ## Describe the target user/application Some users may feel uncomfortable knowing the GPU is running at a higher temperature indefinitely in idle scenarios as much as the GFX card ODM has validated under its own unknown criteria, instead of having the freedom and peace-of-mind of setting a non-zero constant fan speed. Thus RDNA3 users with 0rpm-enabled gfx cards would stand to benefit from additional control over the fan spin/stop criteria. ## How do you plan to validate this feature I would use that kernel interface directly initially and then automatically through a userspace app once that gets made. ## Business case This functionally may improve GPU lifespan long-term at the expense of the fans', which is an arguably logical tradeoff. This would also cross off a parity issue with Windows Adrenalin drivers.
