Examining airflow

post #1 of 9
Thread Starter 
I was just thinking of my airflow, because when I turn my fans off, I don't get a change in temp's.

I think theres too much going in, but im not sure.
This is how I imagined it would look. If I got rid of the top 120mm one (a silly mod of mine) would there be a more efficient airflow? Im curious =]

Oh and the pc is on its side so the heat does not rise upwards.



EDIT: Changed it to the top 120mm not just top one*

My air flow is 3x180mm's + 1 120mm in and 1 120mm out, by doing this I have created a positive pressure case with vertical air flow. Hot air rises...


Yours set up with a horizontal air flow from left to right and up and out should have a considerable flow, if you don’t see any change in temp of the ambient air in your case you might not be running at any load... shrug it seems like an okay set up to me

Time for you to get a new case. The 900 is one of those Antec cases that look better than they perform. Plus it's designed to stand upright. If your case needs to be on its side, get a case that's either designed to be that way, or compatible with sideways orientation.

Your case is cheaper than your mb, way cheaper than your cpu, probably cheaper than your video card, probably cheaper than your RAM. The only thing you have that's cheaper than your case is your cpu cooler.

Get a new case.

^ I concur. To get the most out of your system, don't skimp on the case.

Agreed. My 900 had crap for real airflow and was so cramped once I wanted to water cool.

You should have a bit more air going out then in. What are the speeds of your fans and how messy is the inside of your case?

Yea check your wiring that may be causing your airflow problems. Other then that get a new case. Maybe the Antec 902?

I learned my lesson: no more Antecs. The sole exception would be a DF-85. Until that case, Antec seemed just not to understand airflow.

I bought my first case in a hurry. I had days to learn what cpu I wanted, what motherboard, etc. Not enough time to learn it all. I went with Antec's reputation. I call that case The Tomb. I gave it away. Good riddance.

Stand the case upright and you have a good air flow.
I might change that small lower rear exhaust contraption to one of these PCI fans facing up towards your card/cards and out the top for added intake from below. Will help your card/cards too. I use to use this one (still have it) for a very HOT 8800 Ultra. These cards and case doesn't need it.

It was $8 5-6 years ago, ha.

Or this one for $3 more. It has the option to change direction of one of the fans.
