Here's a simple, yet effective, diagram of the airflow inside my case.
Two Antec fans on the front pulling air inside of the case.
One Antec fan pulling air out of the case through the radiator.
I'm going to run it like this for a little while and if need be, put a push fan on the radiator inside of the case.
These are the Antec fans I'm using: Link to Newegg
These fans, in my Elite 335 anyway, produce more of a low, humming sound.
The "noise" is completely tolerable.
My only complaint with the setup is my wife is sometimes difficult to hear when trying to talk to me from another room.
The exhaust fan on the backside of the radiator is definitely doing work.
When you put your hand on the back of my case when under full load, you feel plenty of hot air coming out of the case.Edited by kidaquarius - 12/20/10 at 4:52pm
