yep they are balanced. so if you paint it, it can inbalance them...(if you put too much paint in one area etc...if its a light coat without the clear coat, you may get away with it..

 

Really? Ive never seen one that looks like its balanced.

 

I'd have thought you really would have to be pretty crap at spraying to put enough on in one spot to imbalance the fan.

 

Thats what I thought.

Not sure on the cooling side of things i think it depends on the electric fan. I do know that they take up power from the engine to spin though. Wonder if anyone has done a comparison on power vs cooling on an electric vs Viscous

 

The viscous fan saps power in the form of parasitic loss but where does the power for the electric fans come from ;) Theres lots of figures for the efficiency of the stock fan but alot of people run electric fans and dont have cooling issues.

The electric ones would have to be less efficient (measuring a like for like fan performance) by nature of them converting mechanical engine power into electricty then back to mechanical, vs the stock fan being purely mechanically driven.

 

I bought mine for pure cosmetic reasons,
