I don't want fancy curves, I'm simply trying to force lock static RPM (full-on mode). In Windows, it's possible to tune fans directly from the AMD Radeon driver GUI app. Maybe override kernel-defined values during boot? It seems that there has to be another way around, like some amdgpu config or something like that. To sum up: seems that I can't edit /sys/ amdgpu-related entries at all Part 2 Systemd: rvice: Failed with result 'exit-code'. Systemd: rvice: Main process exited, code=exited, status=1/FAILURE usr/sbin/fancontrol: line 649: echo: write error: Invalid argumentĮrror writing PWM value to /sys/class/hwmon/hwmon1/pwm1ĭaemon (service) also doesn't work: fancontrol: MAXPWM=255įancontrol: Enabling PWM on fans.įancontrol: Starting automatic fan control.įancontrol: /usr/sbin/fancontrol: line 649: echo: write error: Invalid argumentįancontrol: Error writing PWM value to /sys/class/hwmon/hwmon1/pwm1įancontrol: Aborting, restoring fans.įancontrol: Verify fans have returned to full speed Loading configuration from /etc/fancontrol. Sudo fancontrol doesn't work as well: $ sudo fancontrol Python amdgpu-fan package also doesn't work for me. Neither does sudo sh -c: sudo sh -c 'echo 225 > /sys/class/drm/card1/device/hwmon/hwmon1/pwm1'Īrchilinux Wiki states it should be possible though They edit values directly with echo and looks like it works for them.Īnother guide also recommends configuring fans this way I have also tried sysfs config to edit these params but it didn't work: $ cat /etc/nfĬlass/drm/card1/device/hwmon/hwmon1/pwm1 = 255Ĭlass/drm/card1/device/hwmon/hwmon1/pwm1_enable = 1 $ echo 255 > /sys/class/drm/card1/device/hwmon/hwmon1/pwm1īash: echo: write error: Invalid argument Obviously, it doesn't work due to missing permissions (even with sudo/ root) because it is /sys: $ sudo su I'm trying to lock RPM of my AMD Radeon videocard fans at the full speed: echo 1 > /sys/class/hwmon/hwmon1/pwm1_enable
