The five patches were sent out today on amd-gfx. This is on a fan RPM basis while previously some AMD graphics cards could be controlled on a PWM (Pulse Width Modulation) toggle. It has surprisingly taken a while for this feature that's been sought after by some users, but at least it's here now and useful particularly if using the Linux command-line based AMD OverDrive functionality during overclocking or if trying to get your graphics card to forcefully operate quieter.
The new patches allow for the fan speed target to be viewed/set, the ability to read the min/max fan speed, and to enable/disable the fan sensor all via sysfs, making it easy to read or tune these values from the command-line or easy-to-create scripts. A set of five patches were sent out on Sunday by AMD's Rex Zhu that enable RPM fan settings to be viewed and manually toggled via the sysfs interface.įor those wishing to manually override your Radeon graphics card fan control settings, the AMDGPU DRM driver will be offering this ability via sysfs.
