easy to do. 1 - 12 volt fan. 1 - 12 volt power supply. make sure output of power supply is about 20% more than need of the fan. if .5 amp fan, then get a .6 amp power supply.appropriate wiring. you should be able to get all from Radio shack. the only issue will be if you want the fan running 24/7. if not, you need a timer. simple once a day on/off lamp timers are cheap. programable timers are much more $. if you need more help, give me a call.
