Description bmilreu 2018-10-11 04:01:10 UTC

I'm using the sysfs API with those steps:


To switch to manual fan control from automatic, run
# echo "1" > /sys/class/drm/card0/device/hwmon/hwmon0/pwm1_enable

Set up fan speed to e.g. 50% (100% are 255 PWM cycles, thus calculate desired fan speed percentage by multiplying its value by 2.55):

# echo "128" > /sys/class/drm/card0/device/hwmon/hwmon0/pwm1
To reset to automatic fan control, run

# echo "2" > /sys/class/drm/card0/device/hwmon/hwmon0/pwm1_enable


My RX580 Nitro+ starts beeping a constant high pitched weird noise until I set it back to a fixed value or until reboot. It doesn't happen if start on auto, only after switching to a value then back to auto.

Still present on kernels 4.18, 4.19 and 4.21-drm-next-wip

This is most likely the same issue I encountered some time ago with my RX 580, which is also a Sapphire Nitro+ (Special Edition but that should not matter). I opened a bug report on the kernel bugzilla back then[1].

Yes, seems like the same issue. It would be useful to know if someone with a non-Sapphire RX580 has the same problem.

Comment 4 bmilreu 2018-10-31 20:14:08 UTC

Bug also triggers using the new sysfs API's fan1_target+fan1_enable on latest drm-next-4.21-wip

MSI RX 480 Gaming X is also affected.
