Case/CPU Fans

[Nubbleet]

I'm thinking about adding some fans to my Cooler Master 690 case. I have:
Front: 1 x 120mm intake
Side: 1 x 120mm intake
Rear: 1 x 120mm exhaust

I want to add a side intake and a top exhaust. I also want to replace the other side intake because it sounds like there's a problem with it. The fans in the case now are 1200RPM and I think around 40CFM. Would it be ok to use these fans for the replacements (like airflow wise).

Also I want to use push/pull on my Megahalems heatsink when I get it. Would it be a good idea to use these fans?

Yes and Yes

I think both fan combinations will work fine, thou I would probably look for some LED fans for the case

Thanks. I was gonna buy 2x scythe ultra kazes for the heatsink but they sold out so I had to find next best CFM.

Bleh... just as I get my paypal straightened out they go out of stock .
