Neg. or Pos. case preasure?

[Mikewarrior2]

its true, it isn't all that easy to find Pabst fans here in hte US, and when you do, they tend to be pretty expensive.

Thanks for letting me know what hte enermax 80mm fan puts out. That closes me off to about 115out/120 in.. filters drop the in a bit, so i'm probably either even or slighly negative.

Mike,

My curent config is 85cfm in and 88 cfm out not including my PS fan. Where is a good place to add more intake or do I need more intake?

thanks again

Positive Case pressure as it will lower vortex swirlling of the air near your exhaust fans. I have about 120 in and 80 out.

I forgot that I added a "Hard Drive/CD Rom Cooler" that draws in 31.5 cfm of air. If a P/S exhausts about 30 cfm they should almost cancel each other out.

...and your total airflow is almost as good as Mike's.

Koukla, your airflow is fine..

Hanky, I have too much case cooling... I dont' really need this much.

I am running about 72cfm in and 80 cfm out my intake are all filtered an the slightly positive pressure keeps things much cleaner. case temp actually runs about 4c cooler closed up than it does with the side off. I used to have it set up with 36 cfm going in and 72 out then added the 92mm sunon no more dust now and my case temp dropped 8c cpu dropped 4c. Case temp usually stays around 24c motherboard at 31 and cpu about 41 most of the time.
