nv-temperature

A small systemd service and script that dumps the current temperature of a Nvidia GPU to a file every second on the tmp directory so that fancontrol can use it as a sensor input.

How to get it working

1. Copy nv-temperature.sh to /usr/local/sbin/.
2. Make it executable with chmod +x /usr/local/sbin/nv-temperature.sh.
3. Copy nv-temperature.service to /etc/systemd/system/.
4. Enable nv-temperature with systemctl with systemctl enable nv-temperature.
5. Configure fancontrol and start it.

Sample /etc/fancontrol

INTERVAL=1
DEVPATH=hwmon0=devices/platform/coretemp.0 hwmon1=devices/platform/nct6775.656
DEVNAME=hwmon0=coretemp hwmon1=nct6776
FCTEMPS=hwmon1/pwm1=/tmp/nv-temperature/gpu0
FCFANS= hwmon1/pwm1=hwmon1/fan1_input
MINTEMP=hwmon1/pwm1=30
MAXTEMP=hwmon1/pwm1=80
MINSTART=hwmon1/pwm1=150
MINSTOP=hwmon1/pwm1=0
MAXPWM=hwmon1/pwm1=255

Motivation

Needed to find a way to cool a Nvidia Tesla M40 with PWM controlled fans.
