Bug ID: 105718 Summary: amdgpu reported fan speed looks too high (dual fan Sapphire Pulse Vega 56) Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: shtetldik@gmail.com
I have Sapphire Pulse Vega 56, which ships with two fans. According to this: https://www.youtube.com/watch?v=3mKSrSluxbM&t=1m25s in a normal scenario, fans should spin at under 650 RPM. However sensors report for idle load around 1280 RPM for me, which looks like a double value of the above:
amdgpu-pci-2f00 Adapter: PCI adapter fan1: 1281 RPM temp1: +29.0°C (crit = +0.0°C, hyst = +0.0°C)
pwm1 is set to auto:
sudo cat /sys/class/drm/card0/device/hwmon/hwmon3/pwm1_enable 2
Is this a misdetection, or it's supposed to be like that? Actual fans are pretty silent.
System: Debian testing, x86_64 (kernel 4.15.4).
