Can't control fans after upgrading to Fedora 33 x64 kernel 5.8.14
Hi there,
I've recently upgraded from kernel 5.4.70 to kernel 5.8.14, but there's a problem: I can no longer control the fan speed on my Asus VivoBook Pro N552VX. Unfortunately, I can't roll back to the old kernel as I upgraded from Fedora 32 to Fedora 33, so I'm stuck with kernel 5.8.14. This is the output of sensors-detect: https://pastebin.com/HvKi18Pi and this is the list of sensors: Code:
[FranceBB@router-localhost ~]$ sensors iwlwifi_1-virtual-0 Adapter: Virtual device temp1: N/A asus-isa-0000 Adapter: ISA adapter CPU Fan: 2400 RPM NVIDIA GTX950M: +58.0°C nouveau-pci-0100 Adapter: PCI adapter NVIDIA GTX950M: 900.00 mV (min = +0.60 V, max = +1.20 V) BAT0-acpi-0 Adapter: ACPI interface Battery Voltage: 14.40 V pch_skylake-virtual-0 Adapter: Virtual device Platform Controller Hub: +54.0°C nvme-pci-0500 Adapter: PCI adapter Intel SSD NVME: +34.9°C (low = -0.1°C, high = +76.8°C) (crit = +79.8°C) acpitz-acpi-0 Adapter: ACPI interface Motherboard: +58.0°C (crit = +103.0°C) Code:
[FranceBB@router-localhost ~]$ sudo pwmconfig [sudo] password for FranceBB: # pwmconfig version 3.6.0 This program will search your sensors for pulse width modulation (pwm) controls, and test each one to see if it controls a fan on your motherboard. Note that many motherboards do not have pwm circuitry installed, even if your sensor chip supports pwm. We will attempt to briefly stop each fan using the pwm controls. The program will attempt to restore each fan to full speed after testing. However, it is ** very important ** that you physically verify that the fans have been to full speed after the program has completed. /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed Why is that? |

For those that wanted to know how I solved the issue, by opening Nautilus as root (sudo nautilus) and navigating to /sys/devices/platform/asus-nb-wmi/hwmon/hwmon6 I was able to modify the file called "pwm1_enable" and set it from 2 to 0 and it worked with the Fan now spinning at maximum speed.
