Where should I place my fans?

post #1 of 4
Thread Starter 
I'm building a beast gaming PC but can't figure out where to put the fans...
The general idea is to pull as much air through my H100i as possible.

Fans should be placed like this...

Front = In
Side = In
Top = Out
Back = Out

But I'm placing them like this...

Front = In
Side = In
Top = Out
Back = In

So that ALL the air in my case is vented through my H100.
I'm using:
2x Scythe Gentle Typhoons in my H100 (Super fast and high pressure fans),
a 230mm in the front,
a 120mm in the back
and 4x high airflow fans on the side (These are all quite low pressure fans).
Would this create too much positive pressure or is this fine?

Ideally, you don't want the h100i pulling out all the accumulated hot air, as the cpu cooling won't be as much effective. Keep it like your scenario #1.

For my case:

BACK/TOP - EXHAUST
FRONT/BOTTOM/SIDE - INTAKE
post #4 of 4
Top (H100): In
Side: Out
Rear: Out
Front: In

This is the optimal configuration for your machine and will yield significantly better results than your original placement.
