Lots of discussions about realistic gains from electric fans.I've been replacing clutch fans with fans that take less to turn for decades. I have also replaced stock pulleys with under drive pulleys for the same reason. Never failed to be beneficial. Easily passes my cost/benefits criteria for a good value purchase and a no brainer if replacing the stock fan. What do you consider marginal?
