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/a1wong/it87.git

cd it87
sudo make clean
sudo make 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

Aorus B450 on Ubuntu 24.04 & sensors 3.6.0.
The it87 is detected with no tweak required but sensors shows only 3 fans with 0 RPM:

Not sure someone else has this issue.

I also have 2 PCI cards (HBA & SFP+) with builtin sensors which don't show but that's another story.
