Which fan are you a "fan" of?

I USE THE STOCK 340 BIG *** CLUTCH FAN have yet to overheat and that is sitting for hours in 90 degree heat in city traffic with a stock rad and shroud , now that i have a big 3 core champion rad can't get the car over 180 deg , stock rad ran at 190
Still prefer the stock copper brass rad used it for over 20 years never a problem , i run distilled water and 50% antifreeze radiator is still clean inside
doubt the new alu rad will last that long . i did find some copper brass replacement rads but they were over $600.00 and supply limited
