After hearing all the rave of this fan, Im finally gonna ty it out. Im runnig 2 perma cool fans with no shroud, that are rated at 1200cfm a piece, so im sure i would see a temperature drop with the HHr fan. My question is, what else do I need to run it? Do I need the matching relay and connecter to run it? Or can I use any relay? If so, how many amp relay does everybody use? Im'm running an upgraded 220amp alternator, so power is not a problem.
