NVIDIA GPU-based FAN controller for SUPERMICRO server

This controller enables automatic adjustments of FANs in SUPERMICRO servers based on GPU temperature. Only NVIDIA GPUs are supported since the tool uses nvidia-smi to parse the GPU temperature. FANs are controlled through IPMI tool (impitool) using the modified superfans (https://github.com/putnam/superfans) script.

Requirements

  • Linux (tested on Ubuntu 18.04)
  • Python 2.7
  • nvidia drivers/tools (nvidia-smi)
  • IPMI tool (impitool) with loaded module (modprobe ipmi_devintf)

Tested on SUPERMICRO 4029GP TRT2 with RTX 2080 Ti (nvidia 415.27 drivers).

Usage

Directly call python script (requires sudo access for impitool):

sudo python superfans_gpu_controller.py

Or install systemd service (superfans-gpu-controller.service):

sudo chmod +x ./install_daemon.sh
sudo ./install_daemon.sh

Service is registered for start at system startup. Start and stop it using:

# start
sudo systemctl start superfans-gpu-controller

# stop
sudo systemctl stop superfans-gpu-controller

# check the status
sudo systemctl status superfans-gpu-controller
