I run the 2spd Taurus fan on mine. I took a piece of sheetmetal, cut it the size of the radiator (w/ no shroud), then cut a hole in the sheetmetal the size of the fan and mounted the fan to that w/ the factory taurus shroud around it... long story short... it can only pull air thru the radiator, cools like a bastard, was cheap (fan was like 15 bucks at the bone yard + a relay, some wire, and a 3 position toggle switch. The only time I have gotten it warm since I installed it is when I forget to turn it on. /forums/images/graemlins/doah.gif
