Pc case fan exhaust

I have a 25 cfm 1200rpm fan as exhaust in the back and two 90cfm 2000rpm as intake in front.
1. Do i need to add two more fans in the top? I have space for 2x120mm.
2. I also have two 32cfm 1200rpm laying around. Do I change the back exhaust with 32cfm?
Also motherboard and other specs in signature.
 
Solution
your best option is to check to have balance air flow with the fan you have and made the best set up for it you might have to try to move some around and check the speed they run and temp in the case since they are not same cfm or fan speed at max .
