Case ventilation and CPU cooler

[SystemFailure]

Hi guys so I have a bit of a problem, my case is the Cooler Master CM 690 III (with the acrilic window) and I need 4 more fans. 3 for the case and 1 for my H60 from corsair (120mm fan).

Right now my H60 is at the rear of the case pulling air out, one at the top pulling air into the case (1 slot free at the top), one slot free at the bottom (near my PSU) and my 200mm stock fan pulling air inside.

Noctua is probably the best (quote Linus) at least for my H60 idk.

But i need your help chossing the fans as well as the position of them in my system.

Thanks guys

Have the fronts as intake, H60 in the top as exhaust and either an intake in the rear for more fresh air to the cooler or exhaust to keep airflow constant. I would personally have the rear as intake (filtered).

 

Noctua is the best in terms of overall performance, but they are expensive. I like NB BlackSilent Pro fans myself, as they're quiet, offer good all round performance and don't cost a ton.

I really need some quiet but overpower fans cause my g1 gaming 970 is heating a lot also... My room temps are not that great. Any advice ? Noctua is a possabilitie but they are so ugly...
