Adjust the GPU fan speed

Overview

Each NVIDIA driver and GPU combination supports different methods for adjusting fan speed. There are three possible approaches, and you can try them to control GPU fan speed.

Method 1

Type the command and open the NVIDIA X Server Settings application, and you can

sudo nvidia-settings

Method 2

Switch fan control from auto to manual with the following command :

sudo nvidia-settings -a "[gpu:1]/GPUFanControlState=1" -a "[fan:0]/GPUTargetFanSpeed=100" -a "[fan:1]/GPUTargetFanSpeed=100" -a "[fan:2]/GPUTargetFanSpeed=100"

• "[gpu:0]/GPUFanControlState=1" allows you to manually set the GPU fan speed

• "[fan:0]/GPUTargetFanSpeed=60" sets your desired fan speed percentage (e.g., 60%)

Method 3

If the method 2 doesn't work, try to enable Coolbits setting.

1. same as method 2,switch fan control from auto to manual with the following command

sudo nvidia-settings -a "[gpu:1]/GPUFanControlState=1"

1. Check if the xorg.conf file exists in /etc/X11. If it does not, create one.

ls /etc/X11
sudo nvidia-xconfig

1. Add Coolbits setting in xorg.conf

sudo nvidia-xconfig -a --cool-bits=4

• Here is a guide to the numbers: 1 – Enables the ability to modify the core clock. 2 – Enables the ability to modify the memory clock. 4 – Enables the ability to control the fan speed. 8 – Enables the ability to modify the GPU voltage. For instance, to enable both overclocking and fan control, set it to `”12″` (1 + 4 + 8).

1. Edit Xwrapper.config

   sudo nano /etc/X11/Xwrapper.config

   Comment out allowed_users=console, and add these two lines below

   #allowed_users=console
   allowed_users = anybody
   needs_root_rights = yes

2. Reboot

Method in Windows OS

1. Download MSI Afterburner.

2. Adjust the fan speed in the Fan Speed section

3. Please verify the fan speed using another monitoring tool (e.g., HWiNFO) to ensure the adjustment is successful.
