I considered doing this awhile back, but I couldn't come up with an acceptable way of providing dc power to the computer fan. I first thought about building my own internal dc power supply using a transformer, bridge rectifier, etc. then I looked at a transformerless power circuit. Finally I considered adding a 120vac receptacle to the control panel and using a pre-made plug-in ac to dc adapter.

How did you accomplish this?
