@BDub thanks for the input. Most of the fans I looked at were around 0.5A @ 12V but some were as much as 1A @ 12V. If I’m reading the datasheet correctly, this would actually support up to 4A at 12V. Does this design look right? I’m trying to minimize the types of components used so trying to use either 330 or 1k for R1 depending on what looks right w/ my LEDs. I think either would work for R1 in this design. Is the cap necessary or would it actually interfere with my PWM signal? Thanks again! No making fun of fan drawing
