I guess you could always take the approach of setting a fixed fan speed just below the level of audible distraction and be done with it. That's a simpler approach than even I am taking. A CPU is very tolerant of larger temperature swings, as long as you stay under some critical limit. Well we are t...

EsaT said: Have you tested with different fans know from PWM induced noises? No, and that's a good point. I have a handful of small fans laying about that I test with. My fans are no-name junk that were just salvaged from various old computers. I need to finalize the circuit and then start testing....

This is my first post but I have been lurking these forums for a while now. I haven't seen anything like this, but I haven't seen everything. The purpos...
