[Mgs] Electric Fans

[James Nazarian]

I can think of one other detractor of the metal engine fan.  They make a
real mess of the bonnet when they explode.

?Apart from the faff and expense of acquiring and correctly 
?fitting the electric fan, it's got to be all pro's, no con's.
?
?The mechanical fan is at its least effective when you need it 
?most, when the car is stationary and the engine is just 
?ticking over.  Meanwhile, when you have no need of the fan at 
?all, travelling along at speed, the fan is spinning round at 
?great speed, and sapping precious engine power in doing so.
?
?On the other hand, an electric fan only comes on when you need 
?it, at when it is on it's working as hard as it can, whatever 
?speed the car and engine are doing.  Better cooling, no 
?un-necessary parasitic losses.
?
?Oh, I suppose there is another con, in that an electric fan 
?has more potential to fail.  Unless it falls off, or the fan 
?belt breaks (in which case you are screwed anyway), a 
?mechanical fan can't really go wrong.
?
?Having said that, after two BGTs and one Spitfire I have still 
?never bothered swapping any car I've owned to an electric fan. 
? But that's purely down to the faff and expense involved...
