side fan in or out? - Page 2

post #11 of 13
I had the same question a while back, I received mixed responses as well. To be honest, both theories make perfect sense to me:

1.) Intake Argument: Graphics cards need cool intake air. Positive pressure will help them displace heat.

Alternatively

2.) Exhaust Argument: Graphics cards create a ton of heat, and that heat should be getting out of the case ASAP. (I think I like this argument better, at least in my case, because the graphics card is blowing hot air down at the floor above the psu, which is probably creating a heat "logjam" so to speak for the card.)

I'm getting my fan controller today, so I'll run a test, alternating b/t side intake/exhaust on gpu load. I don't have crossfire, but we'll see how it goes. smile.gif (Maybe it's a good excuse to get a second gpu. You know? For SCIENCE!)

I've never heard of anyone claming or using a side fan as exhaust by means of removing hot air. GPUs need air flow on and around them, especially if you are running two. Hot air will rise and make the card on top run even hotter without proper airflow.
