Exhaust fans

Hey guys,

So I have a bit of a dilemma here... my friend has asked me regarding exhaust fans in his PC.

He has the Corsair 650D and according to him, it has place for either 2 x 140's or 1 x 200 in the top.

Now shall he get a 200mm or 2 x 140's as exhaust in the top?... and the fans that we've found are:

Corsair AF140, both quiet non-led and led versions.
BitFenix Spectre Pro 200mm red led.
Cooler Master MegaFlow 200mm red led.

What would you say/recommend here?... as I'm having a hard time deciding myself and thought I would ask the pros in here for help.
It's a bit lame question to ask really, but I hope any question is welcome here.

Thanks boys! :)
 
Wouldnt really matter but Id personally go for the 140's and have them all rigged up with fan speed reducers straight on to a molex - they really dont need to be going fast to work well in the roof
 
Doesn't the 650D have a single 200mm intake? In that case I'd stick with 1x 120/140 in the rear for exhaust and leave the top fanless so that the heat rises passively and you've got positive air pressure (more intake than exhaust).
