How many fans for my build, and where should I put them?

[anto98]

Hi guys. I was wondering how many fans I should place in my case (Cooler Master Elite 431) and where I should put them.

Unfortunately there is no side duct for the fan, which I was hoping would be blowing over my CPU (i3 3220) and GPU (PowerColor 7870).

One fan is already included at the front. I already have 2 CM fans (120mm), total of three 120mm fans, which I am planning to place:

- 1 front fan at the bottom for intake
- 1 back fan at top for exhaust
- 1 top fan as exhaust

Will this be optimal? All help is appreciated, thanks!
