I have just bought 2 fans for my RAMPS 1.4 case (one exhaust, one intake) they are CPU fans and have 3 wires and a connector on them.
How do I go about wiring these up to the board? I have found loads of stuff about adding the fans to D9, but that is for extruder fans. how do I add case fans? the wires are Black, Red and Yellow.
Thanks.
