The fan controller..huh interesting. Didn't think of that causing the click.
The problem is it wasn't just me switching the power supply on and off. Power outage with my unfortunate location also contributed to it quite a bit.
The reason why I so commonly switch it off is because 99% of the time my PC is put to sleep mode. Windows itself loves booting up randomly at 4AM asking for approval for update and if it doesn't get one it will just update itself without my consent and all my unsaved progress will be gone. So the instant it goes to sleep I switch the PSU off so that the PC can't wake itself up.
Also...I have played a lot on the bios of my Maximus X Formula. I did not even manage to successfully disable RGB so when my pc is powered off it's still on despite the bios being set up properly.
Well I guess I will have to create some external solution. Maybe a timed resistor in series with the line (because at some I will have a main switch for my entire desk setup for every electrical appliance). Yeah I think a resistor quite the power resistor in series then bridged with a relay or contactor will be the easiest and probably most sure way...
