blowhole questions
 

I have a chieftec midi dragon case, an AMD XP 2000+ (palomino) with a zalman cooler (i think i’m going to buy a slk 800 or 900 in august). Because my temps are to high I want to make a blowhole. But I have some questions.

Where?
Now I have 1 intake front , 1 outtake in the back.

how
intake or outtake

Is a papst 4412FGML a good fan for a blowhole?

i start this new thread because i have read and heared too much opposite things

any fan is good for a blowhole, just depends on your tastes in terms of sound.
If you have one extra outtake (besides the PSU) I'd add another intake.
Keep things as equal as possible, but try not to have underpressure, that will suck some air and loads of dust in to all those tiny cracks all over your PC. but then again, better some under then too much over.

so you advise me to have an intake blowhole ? If so where?
I can also use my side panel fan for intake. and then make a top blowhole outtake? is that good?

then i have 2 outtake (+1 psu) and 2 intakes

most people let their circulation go from bottom front to top rear.

Outtake should be near the top, intake near the bottom.

Chieftech should have additional spaces for coolers.
