Manually control a dell server's fan speed based on the nvidia gpu temperature

Why did you make this?

I have an Nvidia P4 in my dell R430 and the server does not adjust its fan speed based on the gpu temperature. This means that after a few minutes of use the card will overheat and my system will reboot :(

This little script fixes that problem by periodically checking the gpu temperature and setting the fan speed accordingly via IPMI :)

Will this work with my system?

Tested and improved to work on the following systems:

PE R430 with single tesla P4

PE R720 with dual tesla P100 (idrac version 2.65.65.65)

The basic requirementes are:

• You have a Dell server and an Nvidia GPU (duh)
• You need to be able to run the nvidia-smi command (aka have the nvidia drivers installed)
• You need to have enabled IPMI over LAN in you IDRAC settings. On a 13th gen server this can be found under Overview > IDRAC Settings > Network > IPMI Settings > Enable IPMI over LAN

You can find a list of IPMI commands to test it here

How to use

Cloning:

git clone https://github.com/Olaren15/dell-fan-control-nvidia.git
cd dell-fan-control-nvidia
sudo chmod +x *.sh
nano *.sh

Edit the dell-fan-control-nvidia.sh file to use the proper IP adress, username and password. You may use a text editor like nano or vim.

username is the username you use to access idrac

password is the password you use to access idrac

ip address is the ip address of the idrac interface

Setting Up:

sudo mv dell-fan-control-nvidia.sh /usr/local/bin/dell-fan-control-nvidia.sh
sudo mv dell-fan-control-nvidia.service /lib/systemd/system/dell-fan-control-nvidia.service

Installing Dependency:

sudo apt install ipmitool

Configuring systemctl:

sudo systemctl daemon-reload
sudo systemctl start dell-fan-control-nvidia.service
sudo systemctl enable dell-fan-control-nvidia.service

And make sure the service is running without errors:

sudo systemctl status dell-fan-control-nvidia.service

enjoy!
