freed00m Posted February 22, 2021 Share Posted February 22, 2021 Hi, I want to ask, if there's a way how to turn off Helios64 without the 100% fan spin. It only takes 1 second but it's very annoying when I want to turn it off during the night. Looking https://github.com/armbian/build/blob/master/packages/bsp/helios64/fancontrol.conf and https://wiki.kobol.io/helios64/pwm/ No luck :Z 0 Quote Link to comment Share on other sites More sharing options...
allen--smithee Posted February 22, 2021 Share Posted February 22, 2021 Hi @freed00m I think you would like to read /usr/sbin/fancontrol. 0 Quote Link to comment Share on other sites More sharing options...
gprovost Posted February 23, 2021 Share Posted February 23, 2021 in /usr/sbin/fancontrol you can comment the lines 517 & 518 to achieve what you want. #trap 'restorefans 0' SIGQUIT SIGTERM #trap 'restorefans 1' SIGHUP SIGINT You will need to stop and restart the service in order for it to take effect systemctl restart fancontrol.service 0 Quote Link to comment Share on other sites More sharing options...
freed00m Posted February 23, 2021 Author Share Posted February 23, 2021 @gprovost - Thx that indeed acomplish what I want. Question, what purpose does it serve? Making loud halting seems like a unwanted behavior. Also what side effects can I expect? the script is at /usr/sbin/fancontrol . 0 Quote Link to comment Share on other sites More sharing options...
Heisath Posted February 24, 2021 Share Posted February 24, 2021 I assume the original thinking of the authors of fancontrol was, that when the programm crashes/unexpectedly get closed, it does not leave the fans at a low speed and possibly endanger the system. The fancontrol does not differentiate between shutdown and exit / kill. And from a system perspective it is much better to have annoying loud fans (but a cool and healthy system) than slowly burning away components while no sound is heard I guess that also answers your second question, if you comment those lines away, the fans wont auto speed up if fancontrol crashes or similar. 1 Quote Link to comment Share on other sites More sharing options...
allen--smithee Posted February 24, 2021 Share Posted February 24, 2021 Line 44 MAX = 255 You will probably want to change this value to your own. nevertheless, I will not advise you not to go below 120, for the obvious reasons cited by @Heisath . If it's still too noisy. you can safely reduce this value (> 35) after modifying the thermal Pad between the board and the heat sink. 0 Quote Link to comment Share on other sites More sharing options...
freed00m Posted February 24, 2021 Author Share Posted February 24, 2021 @allen--smithee Thx for the mod tip, I'll do it when I move and have more time. For the time being I will writte myself a systemd service that apply patch (uncomment the script's traps) and when need for quite termintion, I will comment out the lines to have quite halt). 0 Quote Link to comment Share on other sites More sharing options...
