This is so far wrong its not funny. The laws of thermodynamics state that its impossible to transfer 100% of energy, some is always lost. I can't be bothered reading the whole thread, but KDog, while you are right, the reasoning is: * with a mechanical fan, even a clutched one, it's spinning all the time - whether your engine is cold or not, and whether you are idling at the lights or cruising. * sure an e-fan will use more energy overall if it were running the whole time. But the whole idea with an e-fan is that it only runs when it needs to. Most only come on hard when sitting at the lights; the rest of the time it's a 'free' hp boost, however small, from the engine not having to spin the drag of the fan while driving around. Having said that, another consideration is that, at high speeds, e-fans tend to (I have heard) actually impede cooling because of the design of the fan blades (something to do with the pitch/size) compared to a stock mechanical one.
