Can anyone recommend a good set of electric fans for desert temps?
I've got the Champion Radiator 3-row with shroud and dual 12" electric fans ("550hp rating" says Champion) on my mostly stock '77 280Z. I gotta say, this combo is hot garbage on 100° days here in Las Vegas.
With the stock brass 3-row rad and clutch fan, my temp gauge would very slowly creep higher while idling in stop and go traffic -- manageable with no danger of overheating. Same goes for the Champion aluminum 3-row rad with stock clutch fan and no shroud.
However, when equipped with the electric fan/shroud combo (yes, they're spinning in the right direction), the needle climbs up to 3/4 of the gauge sweep within 15 minutes of stop and go traffic and steadily keeps climbing. It only cools at highway speeds when the fans aren't doing any of the cooling.
