custom-fanbytemp

This script is complementary to ethOS and provide a custom behavior for fan speed based on GPU temperatures

Features

Every 5s, the custom script (as a deamon) will check GPU temperatures and modify /home/ethos/local.conf if necessary.
In the local.conf, a line is modified (each other lines are copied as is): fan c94e13 62 64 62 66 53 64 it controls fan speed of each GPU of your RIG worker.
Only one worker is currently supported.
It will also trigger overclock command to take the new fan speed into account.
After this, the script will check the real fan speed and adjust the conf accordingly.
After your RIG booted, the adjustment with real fan speed is not done until the temperatures are stable.
If the adjustment is wavering, max will be saved and adjustment will stop.
Then it will standby until an new change of GPU temperatures.
An hysteresis of 1 is applied for temperature going down.

go to your RIG and copy custom-fanbytemp-daemon.php and custom-fanbytemp.sh in /home/ethos
modify const CUR_WORKER = 'c94e13'; with your worker id in custom-fanbytemp-daemon.php NOTICE: c94e13 is a SAMPLE rig/[worker]/hostname, change it to the rig/[worker]/hostname of YOUR RIG
modify /home/ethos/custom.sh like custom.sh
restart your ethOS RIG
check your logs in /home/ethos/custom-fanbytemp.log
enjoy your new silenced RIG!

You can manage the daemon with command custom-fanbytemp.sh [start*|stop|restart] *=default
- when stopped, the daemon will revert your fans to globalfan value in local.conf

remove # in custom-fanbytemp-daemon.php
modify the files in test/ folder :
- sample_fan.txt is the list of Fans % speed
- sample_local.conf is your local.conf that is modified by the script
- sample_temps.txt is the list of GPU temperatures
