Once the car is moving the fan performance is almost irrelevant isn't it?
It depends, a 10 kph peak hour crawl will need a fan, once you get up to around 40 kph the fan is not needed.
I prefer electric fans.

Read somewhere not good to use clutchfan on high stall convertor cars or maybe it's waterpump not so good either noticed lots of built 355's gone electric w/pump.
Mine seems to work fine but does have 4500 stally
Wht revs does the clutchfan cut out?
I've just been going through the various suppliers of these and found that the Davies Craig website has some really handy info on clutch fans and how they work. Link can be found here.
Is there a particular standout in brand when it comes to the clutch? Three that I have come across are Davies Craig, TruFlow and Dayco.

That was interesting never knew was different kinds.
When using clutch fans always used factory one off commodores if there was room to fit it...never needed to replace one.
This car has big stally & 4.5 gears...does a lot of slow speed traffic though,been caught in a few traffic jams.Never overheated but notice after long periods heat does slowly creep up BUT an old stocker wouldn't like it either.
Thinking it's a combination of things like under bonnet heat from extractors/engine & high revs at slow speeds(stally) making fan less efficent & water pump possibly cavitating.
It's not too bad just might not be pretty in summer getting caught in traffic jams lol.
