Case Airflow

oxygene · 12 May 2011 at 14:42

I've had my case for a while now, and slowly but surely its filled up with hds and such. I took a look at it recently and though that maybe the airflow isnt at its best. I have no overheating problems at all, and the case it always cool, as are the components, but its always nice to think about these things. Below I have a picture of the same case filled with parts (not mine) which I mercilessly poached off another website. I doodled a few arrows on it showing fans and airflow to demonstrate what I have atm. I understand theres nothing I can do about the gfx card or psu fans flows colliding, but the rest... maybe theres a better way?

This is just a curiosity thing, any input is welcome for the next time I open up the case.

Thats ok, but you got the arrow for the GPU the wrong way around

it sucks up and out the back.

unless you got something different?

And the PSU fan is sucking down and then out the back.

things seem ok maybe a PCI slot exhaust to blow out the hot PS and graphics air?? just my 2ps worth

The arrows in the middle of your diagram are facing the wrong way as air is taken into the Graphics Card / PSU and then exhausted out the back.

You can turn your PSU round providing you have a cut-out on the bottom of your case. Air from underneath the Case will go into the PSU and out the back. (This is assuming the case doesn't sit on carpet which may block the airflow from underneath).

Antec cases like the 902 above have the PSU fan facing up.

Not a 'fan' of pci blowers myself. Had one and it was loud and not particularly effective. In this case, with the GPU and psu sucking air in, it would be counter productive.

Basically, there's nothing wrong with the airflow of the setup above once the arrows are drawn correctly. I have a fan controller and have the bottom front fan spinning faster than the one above to push more air to the psu/GPU. Also i have the rear fan pulling more air than the top fan to let the CPU cooler do it's job.
