Extra case fans needed for 580 system?

[magick]

New system build :-

Fractal Design R3 Case
I5 or I7 with a Bequiet CPU Cooler
Gainward 580 GTX

The case comes with 2x120mm fans one at the front and one at the rear. Will that be enough to keep the components cool and allow for CPU OC?

Should I add a 140mm and if so should I add one at the top or one the side over the GPU?

I want to keep the syetm as quite as possible.

they should be fine, make sure you cables are as tidy as possible to allow for the best airflow.

if you want it as quiet as possible see how you go with the original 2 case fans first.

check how the temps are, also try disconnecting them to see how much noise they make.

then start by improving the original 2 fans if needs be for improved airflow/quietness, then if needed add a 140mm fan to the top of the case.

Thanks for the advice.
