WebApr 19, 2016 · Add a comment 1 Answer Sorted by: 2 You will need to investigate the fan PWM input requirements. Most times they will need a bias to activate the input. If your fans are like this then you may need to add a pullup resistor from … WebFig-1. Under this situation to the first order any low negative voltage(NPN-version) appearing at the emitter would set up an emitter current which would mostly flow to the collector. However a small voltage drop(~0.03V) across collector and emitter of the transistor is required to maintain a current through it.
