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

Can confirm this works on the Gigabyte B850M Gaming X Wifi6E motherboard like a champ.

Gigabyte X870E Aorus Elite Wifi7 required ignore_resource_conflict=1. force_id and force_addr were insufficient.

On my system the it87 module already existed, simply running sudo modprobe it87 ignore_resource_conflict=1 force_id=0x8622 made the fans appear. Is there any downside/risk to this? Is there any reason I need the version in git?

My system:
Linux Mint 22.1 Cinnamon
Kernel: 6.15.10-061510-generic (installed via Mainline)
Gigabyte X870E Aorus Pro

On my Z690 AORUS ELITE AX DDR4 I only get the fan sensors but no control over them.

B550 Aorus Elite AX V2 - fans show up in sensors and CoolerControl, but I have no control over them. ignore_resource_conflict does nothing, I had to add acpi_enforce_resources=lax to GRUB.

B550 Aorus Elite AX V2 - fans show up in sensors and CoolerControl, but I have no control over them. ignore_resource_conflict does nothing, I had to add acpi_enforce_resources=lax to GRUB.

Hi! I had the exact same issue with a similar Gigabyte setup. The reason ignore_resource_conflict doesn't work is that the kernel driver sees the resource as busy, and acpi_enforce_resources=lax is indeed the first step, but often not enough to gain write access to the PWM registers on the IT8686E.

Try the following steps to unlock full control:

1. Update your GRUB definitively
Ensure your /etc/default/grub contains both parameters:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_enforce_resources=lax"
Then run sudo update-grub.

2. Force the driver configuration
The it87 driver needs to be told explicitly to ignore the virtual ACPI device. Create a configuration file:
sudo nano /etc/modprobe.d/it87.conf
Add this line:
options it87 ignore_resource_conflict=1

3. The BIOS "Full Speed" Trick (Crucial)
On B550 Aorus boards, if the BIOS 'Smart Fan 5' is set to 'Auto' or 'Normal', the hardware controller often overrides software PWM signals.

  • Go into your BIOS.
  • Set the fans you want to control to Full Speed.
  • This hands over the PWM duty cycle control to the OS. Once you boot back into Linux, your Fan Control app should be able to down-regulate them from 100% to your desired curve.

I can also confirm that this fix worked on my Aorus B450 Pro Wifi running Fedora43

On Gigabyte Aorus Elite X570 works with just modprobe it87, no parameters needed. Thanks.
