I would like to build this but I do not have the experience to do so with out help. What I am looking for is a 12VDC Var. fan controller with 4 lines suppling at least 60W & 7.5A each with the unit being able to fit into a drive bay in a computer. I have had a little help with this already but need some input as to weather the circuit design is ok#1 or does it need modifications. I am using the LT1083CP in this design. any thoughts comments or suggestions will be of much help also a complete parts list so i can make 2 units controlling 4 lines each.
