Every man likes to be blown!:biggrin:
OK, man, maybe a dumb question but if it drafts so good and all, why do you need a blower?
My temp controller runs off of 110ac and has a 12vdc output, but was only capable of supplying 40mA's. The fan draws about 170mA's so I had to add an external powersupply and an opto-Isolator to the system. Found an old power adapter that plugs into a wall outlet and provided me the 12vdc and was capable of providing 300mA's.
So, basically the temp controller turns the opto on and off while the opto switches the fan on and off.
