5 blade vs 11 blade 911 fan

[Tony Z]

Think about it this way, the 5, 11 or 12 blade was designed to cool a lot more power, cylinders, boost and heat than we will ever need.

The only problem with running a 5 blade fan that I can think of is as follows.

I dont like the look. Yes, if nothing else was available, I would run a 5 blade (almost did too), in all honesty, I REALLY REALLY REALLY REALLY like the 12 blade, but those cant be found in SA, so I opted with the 11 blade.

It all boils down to looks!!! They each have their specific design application, which is much more than we need anyway.
