Phanteks Eclipse P400A Fan setup question

Vardris · December 25, 2021

Hello everyone,

Before I ask main question, I just wanted to share with you my PC build:

CPU: Intel i7 11700k

MB: MSI MPG Z590 Gaming Force

Cooler: Cooler Master MasterLiquid ML240L V2 RGB

RAM: Kingston Renegade DDR4 32GB (2x16) 3600MHz

GPU: MSI GTX 1660 6GB (used from old PC setup until situation gets better)

Storage: Kingston A2000 250gb + Samsung Evo 970 Evo plus 1TB

PSU: Cooler Master MWE Gold V2 Modular 750W

Case: Phanteks Eclipse P400A

I've been planning to buy few more fans to increase airflow in my P400a and I wanted to hear your opinion for fan setup in this case.

I have mounted ML240L in front (2x120mm intake fans). Unfortunately, I was not able to mount AIO on top because of motherboard heatsink size. Rear fan that came with case is exhaust fan made by Phanteks.

Based on current fan configuration, I have available slots:

FRONT: 1 (1x120mm)

TOP: 2 (2x120mm or 2x140mm)

Rear: 0 (If default case is not good enough, I can replace that one as well)

My initial idea for two slot at top of case, would be to get 2x140mm fans. Probably same model as my AIO (if im not wrong, it should be Cooler Master Sickleflow 140 instead of 120). And probably 120mm version for front.

Now, should I buy two or three additional fans, which one of them should be intake or exhaust, sizes, etc.

What do you guys think?

Thanks for answers in advance!
