GK55 Linux Fan Control

warlord0

Is it possible to control the fan speed in Linux? Maybe a BIOS upgrade required.

I have it running Manjaro Linux (headless web services) and the temps are pretty low, for my usage case at least.

I have found the ITE IT8772E chipset controls the fans and temperatures.
This is supported by lm_sensors
Which means you should be able to control the fan with any PWM tool.
I believe however the chip itself controls the fan based on temperature.

Hey, thanks for the response.

You gave me some ideas, but try as I might, I can't get Manjaro to see the it87.

Seems there are hurdles for getting this driver to load.

Out of curiosity, what distro are you using?

Good old debian :)

thanks.

If the built-in utilities don't work or are not compatible with your motherboard, you may need to explore third-party software options. 'fancontrol' is a commonly used tool, but it may not work for all hardware configurations. Other software options, such as 'SpeedFan' or 'NoteBook FanControl' (if applicable to your desktop machine), might be worth exploring as well.

I think it is possible to control the fan speed in Linux. You can use tools like "lm-sensors" to monitor the temperature of your system and "fancontrol" to adjust the fan speed accordingly. However, not all motherboards support fan speed control, so a BIOS upgrade might be required in some cases.

It's an informative topic. It helps me very much to solve some problems.
