Well...just a note.. unless you have some neat cowling around that heatsink, it's setup for convection better than forced air. To get maximum effect, the air has to be blowing lengthwise over the heatsink, and preferably through the holes as well.

Try to wind some wire in your toroidal transformer until you get the voltage you need. For me it worked with about 10 turns, to get around 7 V. I am using CPU fans inside the case.

Don't forget a rectifier and an optional cap as CPU fans are DC
