A Simple Mosfet Fan Duct

If you find your Mosfet in your Ramps getting Hot, then maybe you need a Cooling Fan! I have not decided on a mount point for it yet, but intend to to run twin 200mm heatbeds, the Mosfet will get very hot, so a fan is needed plus a good heatsink Suits 40mm Fan The holes are the right size to screw in M3 screws directly Use a driver on a slow speed to drive them in I suggest reverse the Fan to draw away from the Mosfet Updated Monday, 27th, April Now Made and Pictures added
