The nice thing about e-fans was the A/C efficiency while at slow speeds or stopped.

I guess I'm on the other side of the spectrum as far as opinion goes. I felt somewhat harder pull in the top end, you're definitely recovering parysitic power you previously lost with the mechanical fan in place, and you gain a lot of work space. If you wrench on your own vehicle it makes everything worth it. and you can put your own kit together very simply for under $80+/-.

Skimp on any one of those things, and you WILL eventually have problems.
How many factory e-fan vehicles running around, anyone?

How many 'factory' e-fan vehicles are 5500# that can tow 9000#+ ?
How is an electical fan more or just as reliable as a fan clutch and fan?

On a side note, my 95 Mustang has an e-fan and it's still functioning properly. The car does only have 70 k km's (40 k miles'ish?) on it though.

The key is over-engineering - where the intended useage is factored into the root design - the fan designers know the duty-cycle requirements, target application, and proceed accordingly - for QUALITY ( e.g. OEM) fans. We are not talking cheap pc fans here, lol.
Perhaps not more reliable - but essentially just as reliable - over the projected lifetime of the system. With the attendant added benefits of ( potentially) better cooling, access to other components, better a/c performance, and less parasitic loss. It worth noting that mechanical systems break too - and I personally just hate the concept of a fan clutch that never fully disengages or freewheels - they always drag.
Actual vehicle is of no relevance - engine cooling is engine cooling. Cooling systems are sized to the vehicle, so duty cycles will be similar, if the efan is also sized correctly.
Oh - and the new Chebbies p/u's have electric fans
I have never, ever had one single efan install fail - no melted wires, no burned relays, no seizures, no overheating. Nada. I attribute that to my aformentioned points in my preceeding post.
We should probably just leave it as agreeing to disagree - we have different viewpoints & I'm perfectly cool (pun intended lol) with that.

I probably said the same thing I'm about to say now, but my opinion - I've read too many posts here about fan controllers and wiring burning up to really trust electric fans myself. I don't think the dollar spent versus the gains (if any) received are worth the effort.

Amen! Why make something more complex than it needs to be when the gain is so small?
