Gigabyte Aorus - Linux fan control.md

PWM fan control in Linux with a Gigabyte Aorus motherboard

• install lm-sensors with your package manager

sensors

If it won't show any fan/speed, continue

sensor-detect

Say YES to at least "Super I/O sensors"

Expected output:

Trying family `ITE'...                                      Yes
Found unknown chip with ID 0x8688

If similar, continue

git clone https://github.com/frankcrawford/it87

cd it87
sudo make clean
sudo make install
sudo modprobe it87 ignore_resource_conflict=1 force_id=0x8622

sensors

The fans should show up now, if yes, continue to make them available at boot:

echo options it87 ignore_resource_conflict=1 force_id=0x8622 > /etc/modprobe.d/it87.conf
echo it87 >> /etc/modules

From trying out these instructions on Z390 AORUS ULTRA, I found that only one of these steps is sufficient.

• Get a recent Linux kernel and make sure to actually set force_id=0x8622, it is necessary. Otherwise you'll be getting all fans showing 0 RPM.

  With this, I think we are telling the sub-par built-in driver a wrong device ID so that it can display something via support for some other device.

OR:

• Install this custom kernel module frankcrawford/it87 aka it87-dkms-git. Then reboot, otherwise it's not actually kicking in.

  With it, no settings are necessary and it seems to detect and apply the correct device.

this is great, thanks! I'm all set on my aorus b550 elite ax v2
