pwmconfig can't find fans, which are modifiable in uefi Bios

I would like to change the fan speeds on my PC. In the Asus BIOS settings, this is possible with PWM and DC (three of them are connected with 4 pins), but the running operating system seems to have problems doing the same. The two I want to change manually have the names CHA_1FAN and CHA_2FAN on the motherboard. > cat /etc/sensors3.conf | grep -i fan # Fans label fan1 "PSU Fan" label fan2 "CPU Fan" label fan3 "System FAN2" label fan4 "System FAN3" label fan5 "System FAN4" # Fans label fan1 "CPU Fan" label fan2 "System FAN2" label fan3 "System FAN3" label fan4 "System FAN4" label fan7 "PSU Fan" > hwinfo | grep -i fan acpi-fan: /devices/platform/PNP0C0B:03 acpi-fan: /devices/platform/PNP0C0B:01 acpi-fan: /devices/platform/PNP0C0B:04 acpi-fan: /devices/platform/PNP0C0B:02 acpi-fan: /devices/platform/PNP0C0B:00 acpi-fan: module = fan type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" E: DRIVER=acpi-fan E: DRIVER=acpi-fan E: DRIVER=acpi-fan E: DRIVER=acpi-fan E: DRIVER=acpi-fan [ 0.062442] rcu: Adjusting geometry for rcu_fanout_leaf=16, nr_cpu_ids=4 fan 20480 0 - Live 0x0000000000000000 Driver Status: thermal,fan are active Driver Activation Cmd: "modprobe thermal; modprobe fan" > sudo pwmconfig [sudo] password for root: # pwmconfig revision $Revision$ ($Date$) [...] /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed heimchen@DESKTOP-G0NG8DL / > The system is OpenSuse Leap 15.5 and lm-sensor does not seem to be installed. I tried downloading it from source and compile it, which worked but there is still nothing with this name on my disk.
