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...
