I'm planning to buy a Corsair 5000D Airflow case, and i want to instal 6×120mm fans as intake(3 in the front and 3 on the side) as for exhaust i will have 1×120mm in the back and a 280mm AIO on the top(push pull configuration: 2×140mm push and 2×140mm pull). My question, are there to many fans as intake? I could always lower the rpm on the intake to balance the pressure inside the case, thus lowering the noise as a side effect.
