Thank you all for the replies! Good info here but the original question still stands - even if it is possible to adjust fan settings in BIOS etc., what if that was not an option?
Will the sensing circuitry for 6 fans overload a single PWM Generator based on a single 555 timer?
Sorry if this is too much a "beginner" question but I am not an electronics guy.
If nobody can tell me, how can I find out? Can a good multi-meter measure accurately the amperage (average?) of a PWM signal?
Or maybe the way this circuit works is that the PWM Generator will emit as strong a signal as it can and I can hook up as many "receivers" as I want and nothing will get overloaded and blow up. Maybe the worst that can happen is that the signal will be too weak to detect if I hook it up to, lets say, 100 "receivers".
I don't want to just try it and fry something on the motherboard.
Thanks!
