This python script reduces the noise of a Dell R410 server by controlling the fan speed with IPMI commands.
The original scrip was provided by marcusvb/r710-fancontroller on Github (Big thank you to Marcus)
The script was modified to run directly on a lightly loaded R410 running Ubuntu server with two L5640 processors.
Things changed:
- Removed harddrive temperature check
- Check CPU maximum temperature
- Base CPU temperature settings on cpu Tcase rating (68 deg C for L5640)
- Script runs directly on server instead of on a remote machine
It's recommended to install this script via systemd, see the .service file provided. You can install it as follows:
# Place the service file in the systemd directory
nano /etc/systemd/system/fan-controller.service
# Make executable
chmod 644 fan-controller.service
# Place the python file in the root/scripts directory
nano /root/scripts/fan.py
# Make executable
chmod 644 fan.py
# Reload systemd, enable the service and start it.
systemctl daemon-reload
systemctl enable fan-controller.service
systemctl start fan-controller.service
# Check to see if it's running
service fan-controller status
This allows the script to be enabled at boot.
