Air flow

[Smizack]

Ok, got an air flow - pos/neg pressure question.

I'm gonna have all the fans on 12v. so it ought to be kinda simple. Except the psu fan. I don't know if it's on 5 or 12 yet. (I haven't powered it up)

But anyway. I'm gonna have 2 80's blowing out and 2 80's and a 120 sucknig in. And one of the suck-in 80's in gonna be the psu.

So is that too much positive pressure or just right or what?



Oh yeah, BTW JBell. I dont' need to borrow your hole saw. I just used some cutters. It worked good I just had to tighten it up a bit so it made a cleaner cut.;)

DUDE I MAILED IT YESTERDAY!!!!!


As for air pressure *calms down* leave the PSU blowing out NOT sucking in!!!

creating positive air pressure will create extra dust as you force more air in and it has harder time escaping - by setting up with negative pressure think of it as a vacume it will suck dust and other goodies out of the case.....


*still pissed*

Don't worry I'll find something to drill! hehe;)

Why not? It's gonna be right in front of an A/C all summer. So I thought it would be a good thing.

Ok, what about turning around the front 80 so that I have 3 80's pulling out and 1 80 and 1 120 sucking in?

And if it will make ya feel better, I'll send some amd stickers back with ya!;)

no you need some clean air drawn in - from as low as possible BECUASE cold air always sits on the bottom..... (heat rises) so set your fans in back to blow and the ones up front to suck.and set the 120 (if on top to blow) if on side panel by pci cards then have it suck in........ and get a blow hole installed if you don't do a blowhole it wont kill you - a lot of people see advantages by possitive air over negative... negative works better for me right now....
Thanks for the stickers!

Ooooo k. I'll turn it back around.... Sheesh! hehehe
The 120 is in the back, a little below the psu. I gotta have that one suckin in. But that's a good idea anyway. I need to try Negative, and see how it works. I've always used positive before.

Thanks man.

BTW. On my comp right now the psu is sucking. I haven't had a problem with it set up like that yet, but I see your point.

Hey man. I got it today. I'll get it back to ya soon with your case badges. What all do you want? I got 2 or 3 XP's and a lot of athalon and durons.

$20 is a good deal for that. It looks like it costs around $45.

Well, they arrn't cheap. At least not here. I think an 80mm. or 92. don't remember, was $37 and it was a pretty generic looking one at that.

Yeah it is. Much cheaper than anywhere around here.

just add up the cfm for each fan and make it as equal as possible

equal= yatta cooling
