[WORKAROUND] /usr/bin/pwmconfig: There are no pwm-capable sensor...

trdnt · 2024-05-13 09:37:25

I'm on an Asus Vivobook K3405VC.

I'm trying to increase my fan speed, since it only goes up to about 4100 RPM (even on very high temperatures), even though I know the max is 6600 RPM.
I'm trying to follow the Arch wiki article about fancontrol, but I ran into this error when running sudo pwmconfig:
/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed

I already ran sensors-detect, and when I run sensors I can see my RPM.

I'd appreciate any help.

Please tell us what you have done until now.

Arch wiki article about fancontrol

Asus has it's own wiki entry for fancontrol: https://wiki.archlinux.org/title/Fan_sp … US_laptops (which does the prerequisite for fancontrol via lm-sensors)

Yes, that's what I followed.
Here's everything in my /sys/devices/platform/asus-nb-wmi/hwmon/hwmon4/ folder:
device/ fan1_input fan1_label name power/ pwm1_enable subsystem/ uevent

So I can use
# echo 2 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1_enable # Change fan mode to automatic
# echo 1 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1_enable # Change fan mode to manual
# echo 0 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1_enable # Change fan mode to full speed

But not
# echo 255 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1 # Full fan speed (Value: 255)
# echo 0 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1 # Fan is stopped (Value: 0)

Anyways, when I try using asus_fan, modprobe results in
modprobe: ERROR: could not insert 'asus_fan': No such device

I can't use ec-probe because I don't have Windows on my laptop.

jl2 · 2024-05-13 11:39:09

But not
# echo 255 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1 # Full fan speed (Value: 255)
# echo 0 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1 # Fan is stopped (Value: 0)

did you set it the fan mode to manual?

modprobe: ERROR: could not insert 'asus_fan': No such device

did you install your [your_kernel_name]-headers, https://aur.archlinux.org/packages/asus-fan-dkms-git/ and rebooted?

I can't use ec-probe because I don't have Windows on my laptop.

provided your model offers such feature in Windows.

=> if it works on windows it might work on linux

and, how did you test the 6600rpm? with the full speed fan mode?

I can't, it results in
bash: line 1: echo: write error: Invalid argument
Or if I try with vim
"/sys/devices/platform/asus-nb-wmi/hwmon/hwmon4/pwm1_enable" E514: Write error (file system full?)

did you install your [your_kernel_name]-headers, https://aur.archlinux.org/packages/asus-fan-dkms-git/ and rebooted?

Yes

if it works on windows it might work on linux

The problem is, I have to change the fan speed mode to check which register changes, but I can't do that in Linux. If I could I wouldn't be here

and, how did you test the 6600rpm? with the full speed fan mode?

Yes

I think I figured out why the fan won't run 100%.
Apparently according to Intel "high temperature" is only 100C+, so even when the temperature is 95C the fans won't run 100%.
So what I need to do is lower the "high temperature" and the "critical temperature". I still have no idea how to do that.

jl2 · 2024-05-14 06:23:39

Apparently according to Intel "high temperature" is only 100C+, so even when the temperature is 95C the fans won't run 100%.

If the measuring gets its information from sensors: https://wiki.archlinux.org/title/Lm_sen … ing_values
else, check the files in '/sys/class/thermal/thermal_zone*/'. it might be controlled there.

Alright, thanks.

I found both
/sys/class/thermal/thermal_zone0/trip_point_0_temp

and
cat /sys/class/thermal/cooling_device*/cur_state

But I'm worried that changing them would cause damage.

jl2 · 2024-05-15 07:06:14

Sorry, I need to have more info, can you post the output:

for i in /sys/class/thermal/thermal_zone*/; do x="${i#/sys/class/thermal/}"; x="${x%/}"; echo "$x: $(cat ${i}type): $(cat ${i}temp)"; for x in $i/trip_point_*_type; do echo "  $(cat $x): $(cat ${x%type}temp) ($(cat ${x%type}hyst))"; done ; done

for i in /sys/class/thermal/cooling_device*/; do x="${i#/sys/class/thermal/}"; x="${x%/}"; echo "${x}: $(cat ${i}type) ($(cat ${i}cur_state) / $(cat ${i}max_state))"; done

And the output of "sensors"

let's try setting the throttling trigger very low and look what happens if you pass it:
(This should be safe - but still, IF you see high temperatures (90°C) IMMEDIATELY reboot, this will also revert the changes)
If you rebooted since, check if the zones are still the same and replace them accordingly!

echo 60000 | sudo tee /sys/class/thermal/thermal_zone0/trip_point_0_temp

This should set it to 60°C.
Put some load on the cpu with e.g. 'stress --cpu num_cores' (available as the stress package)
If it doesn't work, try:

echo 60000 | sudo tee /sys/class/thermal/thermal_zone6/trip_point_1_temp

I'm getting Permission denied on both commands, even when I run it as root.

jl2 · 2024-05-15 17:32:19

Please post output, not only words.

I'm getting Permission denied on both commands, even when I run it as root.

sudo or su? And did you do 'echo > whatever' or 'sudo tee' like I said?

We could also just set the fan mode to full speed when the CPU temp exceeds 85°C, but let's first try the thermal throttling

Both sudo and su, I also copied the exact command you posted.
I would rather set the fan to full speed than throttle the cpu, I don't really mind the noise.

I don't even know if it throttles or changes the fan speed.

here's some fancy scripting:

#!/bin/sh

while true; do
	if [ $(sensors coretemp-isa-0000 -j | jq '."coretemp-isa-0000"."Tctl"."temp1_input" > 85') = "true" ]; then
		# please edit the line above with values from:              ^      ^              ^ Temp to turn it on
		# sensors coretemp-isa-0000 -j | jq
		echo 0 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1_enable # set full speed
	else
		echo 2 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon[[:print:]]*/pwm1_enable # set auto speed
	fi
	sleep 3 # refresh seconds
done

Replace the values and run it on startup with root.

If you don't know which values to put in, just post the command here.

Thank you so much!
I hope all the jumps from 2500 RPM to 6600 RPM won't be a problem.
