Air flow
 

just a random question , is it beter to have + airflow or - eg have more CFM going than going out yer case

you should have equal intake and exhaust. if the intake lets too much in and the exhaust can't release (heated)air efficiently.

just keep it even

Hmmm here are my .02...

with negative airflow you will not have as efficient heat dissapation, like xMerCLorDx, pointed out...

If you have a too positive air flow, you will get more acumulation of foreign particles in your case: Dust... so you will need to use some type of filtration on your fan...

Sry if I didn't really answer your question, but it's one of personal choice...

filtration
 

how would you filter it?

EQUAL!

you dont want a near vacuum case
nor a hot gas chamber

it is proven that equal amount of air movements is best for ventilations.


filter is nice...
you know those black foam packs that come in a mobo box?
with a good thickness and holes...
it makes a cheap and very ghetto filter

just duct tape the corners and voila!

Actually I have a slight vacume in my case, sucking all the air out + some extra and I now have 2 degree colder chip, before airflow was equal.

mobo black stuff
 

oh.. glad i saved that black stuff.. should i use that on the power supply too? that gets pretty dusty as well
