[Kadir-1]

Hello guys,
So i finished moving my parts to the new case but i want to put some fans there are 2 places for fans but they are near motherboard if i put them will they do any harm to motherboard, and I'll definitely put one on the back but how should i put it like exhaust or intake fan ?

Optimal air flow is usually intake: on front and bottom. exhaust: back and top.

And if i add one on the back will i cool the pc ?

If you add one to the back as an exhaust it will pull more air through your PC, thus aiding in cooling your components.

I wouldn't be afraid to add one to the front also (even close to the motherboard). Ideally you should place one in the front as an intake and one on the back as an exhaust.
