What/How many case fans should I use?

Solution
It looks like the case comes with one 120mm fan at the back side for exhaust.

Honestly, with the specs you have that will likely be enough. If you have the budget and want to be extra sure you could get one more 120mm to suck air in the front. Optional.

Good luck!
