Looking to keep case cooler

[ajhoyt1224]

So I have a decent desktop case will post link at end of post but it has 2 slots at the top to mount two fans inside and I am wanting to know what sort of fans should I get for them that are quiet but reduce heat inside very well.

Unless you have the intake to match the extra exhaust wont mean too terribly much.
Noctua makes some quality fans for future reference.
