the reservoir already gets a nice blast of cool air from the radiator fans... but the problem with this is that the reservioir is still in an uncontrolled enviornment. so even a very large fan can only do a small amount of cooling to a constantly moving liquid, in a hot engine bay, i can't see a fan cooling the liquid any more then 10 degs, at most. but if i could bring the reservoir temp below freezing and then have it insulated, i think it would provide a lasting cooling effect for the duration of the run. no only that, but the unit could be mounted securly... it would be just as likely that the fridge would come loose as the radiator would...
