# 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`):
|
|
```bash
|
|
sudo python superfans_gpu_controller.py
|
|
```
|
|
|
|
Or install systemd service (`superfans-gpu-controller.service`):
|
|
|
|
```bash
|
|
sudo chmod +x ./install_daemon.sh
|
|
sudo ./install_daemon.sh
|
|
```
|
|
|
|
Service is registered for start at system startup. Start and stop it using:
|
|
```bash
|
|
# start
|
|
sudo systemctl start superfans-gpu-controller
|
|
|
|
# stop
|
|
sudo systemctl stop superfans-gpu-controller
|
|
|
|
# check the status
|
|
sudo systemctl status superfans-gpu-controller
|
|
``` |
