Question: Case Fans Intake/Exhaust Setup

post #1 of 19
Thread Starter 
sup guys? ish yo boy, croy. lol just wanna ask how you guys setup your case fans for proper cooling.

also i wanna ask if i did the right setup:

Side Panel: 120mm intake

Front: 80mm intake

Rear: 80mm exhaust

and just to be sure. how would i know if the fan is blowing or pushing if there is no indication?

TIA OCN.

The setup is right, but to prevent dust build up inside the case, put a dust filter for the 120mm intake fan. If your not cool with a getto dust filter buy something like a Demciflex.

About how to know if the fan is positioned to push or pull (intake or exhaust), there are 2 ways:

1. Through visual inspection of the fan, the side of the fan that has the plastic supports for the bearing is the side through which the fan directs the airflow.
2. Take a small piece of paper, or a napkin and put it near the fan (while the fan is running ofc) from the outside of the case. If the paper is sucked towards the fan then the fan intakes if it's pulled away, then that fan exhausts.

sounds about right, if you have any other fan holes put them as intake and try to put a fan in the 5.25" bays if you have vents in the drive bay area

you don't allow your GPU to have fresh air

You will be pulling air away form your GPU fan, replace the PCI slot covers with "vented" ones, and use it as an intake to feed your GPU cooler cool air from outside the caes, or you can remove the PCI slots all togeather.

Yes but they wouldn't relate to you since you have no top fans and also 2 of yours are 80mm...it's old stuff.

Anyways the dust filters must be installed on all intake fans so on your front 80mm fan (if your case doesn't have 1) and another 1 on the 120mm on the side panel.

If your Thermaltake Contac is mounted vertically pushing air towards the rear, i'd advise searching the forum for tips on how to install a fan in the 5,25' bays to assist with CPU cooling BUT only if your case has mesh in the front, otherwise......it will just screw the airflow (maybe).

Can you read this articles real quick, they convinced me on positive pressure:

http://www.silverstonetek.com.tw/techtalk_cont.php?area=usa&tid=wh_airflow

Also check ehume's guides on how to improve case airflow. If your willing, in time you could modify your case and make more holes for fans.

Wire management also improves airflow so be sure to address this issue.
