Maximize airflow in define mini C

[thirdparty]

I am planning to put 3 exhaust fans ( 2x 140mm on top and 120mm on rear) and 3 intakes (2x 140mm on front and 120mm on bottom). Is that a good idea? Or too many fans actually hurts the airflow. I have 2 120mm fans I planning to keep now but i kinda regret I didn’t go for 140mm at the beginning thus this plan comes out...

Too many fans don't hurt the performance as long as they're all sort of pointing in the same direction, but it might become quite loud.

 

For a case such as the Define C I recommend two fans for intake and one fan for exhaust

or if you have radiators involved

three fans as intake and two fans at the top for exhaust.

currently I am running 2 p12 pwm as front intake and 2 ml120 as exhaust (rear and top). But the ml120 with dust filter on the top cant really push air through it... So I am thinking to replace it with another p12/p14. My current idea is to buy 2 p14 pwm as front intake and using the existing p12 as exhausts ( rear and top).

that sounds perfect. The p12 has better static pressure against the filter, and the 14s are great in the front. I have a meshifyC, and this would be my setup if i used an aircooler.
