Fan Configuration Problems

Hi, I'm trying to configure the fans of my laptop because my graphic card temp threshold is getting activated with the most basic of applications. I know my fans aren't getting to their max speed because I've heard them before and now they aren't as loud, not even close, though I don't know the max rpm of my fans.
I followed the fan speed control wiki page and used the sensors-detect command, but after that the pwmconfig command returns "/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed" and I found myself stuck at that point.
My laptop is a HP Pavilion Gaming 16-a0061la, the motherboard is a HP 87AD 32.31 and has a dual gpu (nvidia gtx 1650 mobile)

$ cat /sys/class/hwmon/hwmon4/name
nvme

$ ls /sys/class/hwmon/hwmon4/
device  power  subsystem  name  temp1_alarm  temp1_input  temp1_label  uevent

$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +50.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +48.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +49.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +47.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +47.0°C  (high = +100.0°C, crit = +100.0°C)

                       (crit = +79.8°C)

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +54.0°C

As the wiki says, I tried increasing the fan divisions to be able to see the rpm but I got an error:

$ cat /etc/sensors.d/fan-speed-control.conf
chip "coretemp-isa-*"
set fan0_div 4

# sensors -s
Error: File /etc/sensors.d/fan-speed-control.conf, line 2: Unknown feature name
coretemp-isa-0000: No such subfeature known

I was planning on making the fans go from 0 to 100, I don't really mind the noise if the laptop is getting it's maximum performance, but even after reading lot's of forum posts I don't know what else to try.

Re: Fan Configuration Problems

The vast majority of notebooks do not allow you or the OS to control the fans, so far so unspectacular. Try an UEFI firmware update and check UEFI settings. Your best generic shot if you really think you need to be able to do this from linux and a misconfiguration from linux is the culprit would be trying nbfc-linux or so: https://github.com/nbfc-linux/nbfc-linu … /README.md

More generally speaking what makes you certain you are running into GPU temp throttling? Do you have sensor/log output for that from actually running into such a situation/did you check nvidia-smi since GPU fans are usually seperate from CPU fans?
