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.

Installation

  • 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!

Usage

  • 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

Tests

  • 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
