im all for e fans...did FAL and Altima...Altima were loud and FAL were quiet. I did the DTC fan controller which worked perfectly...kept temps low and ran when engine off too to keep things cooling afterward...no issues with voltage drop personally but I only run radio and lights...no ac...better gas mileage and revved way faster...I feel we need some dyno differences to get some real info and settle this!!!

It would be interesting to know how much mechanical energy the stock clutch fan actually draws from the engines performance as well as overall efficiency (cooling) as compared to an electric fan

Obviously a V8 is different, but the "science" is there.

SCIENCE! Some really good points in that video, but I feel as if it is missing some key items for this thread specifically. Covering the mechanical draw of an alternator running an electric driven fan in comparison would have really completed it. Also testing how effective each setup was a keeping the engine at an optimal temperature.

Some interesting points lie there though. The advantages to having a clutch fan to steal less power as compared to other solid-mounted/aftermarket ones. Especially the fan shroud segment, which was already talked about in this forum to be important- stealing an insignificant amount of power, but from my understanding was doing a poor job pushing air through the radiator a.k.a less efficient cooling the engine
