I\'m not sure exactly what this fan assembly is, but if it\'s just a small fan and power supply, $45 is kind of step IMO. Have you thought about just buying a small computer type fan and a small 12v power supply? You can pick that stuff up at radio shack for a few dollars, or order then through Mouser / Digikey.
Brad I would definitly try to make some slots across the canopy above the lights to release the heat , I can garuntee it will make a diffrence in temp.. Im not understanding where the fans will be mounted , Is there a place where you can mount them so there acting as an exhaust for the heat built up from the lights ?
Cant believe they didnt sell them with the fans already in the system.. Anyway that looks like the way to go.
