I have a D.C. Speed Controller from Jaycar (10A 12VDC Motor Speed Controller Kit) which I have built to control the fan speed of my case fans (I have two, I'm not connecting the CPU_FAN). I have a case plate which has a pot on it and a switch to turn the fan on and off.
My problem is I'm not sure where to connect my two fans to the speed controller and where to connect the on/off leads to the speed controller also.
This may sound confusing, so I've added pictures to help!
Any advice is greatly appreciated!
