Is my setup ok?

[lazerin]

Hi,
Can you guys please tell me whether the setup I have in my case is sufficent.

All suggestions welcomes :)

[Nico3k]

might want to consider some more exhaust... also the sealed duct for the cpu needs an exhaust i believe. also you might want to have a different blow out than letting your psu do it.


:D

Reverse the fan in the sealed duct to have it suck air out.

Change the duct to have it suck from the base of the HSF.

That way you have increased the air velosity across your HSF.

Good Luck,
:cool:

[lazerin]

my duct cannot be reveresed or else the fans will be fighting with each other.

then cut a hole in your duct and put a small fan on it so the air can escape... like a graphix card chip fan.

[Kendan]

basically you need more exhaust. If the duct is working well then all you need to do is find a way to get the hot air out. The Power supply fan is not enough for all the fans you have. Good Luck.

Uh why? The air is escaping through his cpu heatsink! That is exactly as it should be. To decrease the overpressure in the case, and thus to increase the amount of air movinf throught the cpu sink I'd reverse the upper front intake to exhaust.

[Nico3k]

yeah... it doesnt make any sense if the hot air stays in the case. its just as bas as if you didnt have any fans :D

oh i thought that the duct went all the way to the motherboard so there is no air escape... my bad :o

[lazerin]

ok. so u guys r saying i need more exhaust.
how about this:
i'll take the upper front intake n stick it infront of the psu?

i've drawn a pic of it. the red fan is the one that i will put. will this work?

No that still has that fan as an intake. Just turn it around!

[lazerin]

huh?
what im saying is that i'll take out one of the intakes n put it at the front of the psu so that there is double exhaust on the psu.

but will this make the psu hotter?

[CSaddict]

Psu's can barely cool themselves let alone your case. The psu fan should not even be considered a case cooling method. Your airflow needs to be front to back or back to front or in some manner where it can flow large volumes of air and get it in and out as fast as possible. You might want to consider added an intake fan on the side of your case blowing in the area of the agp slot. I installed an fan there and it drop case temp considerably.

[ajrettke]

I think your setup would be fine if you did these small steps:

remove the duct
take fan out of the duct
mount fan to exaust where the duct was before
drop kick the duct and swear to never use one again

[dansonang]

I like lazerin's pic and that is what I am about to say

I say leave the duct if its working well...
But you need to decided on some sort of exhaust definitly...

Ah ok I thought the box was the entire case. Still, I agree with the others here that it is a poor idea. I stand by my earlier advice.

top blowhole

That is fine too, but I think it's a waste of effort. Simply turning the freaking top front fan around will have a good effect already... no need to go fan-crazy.

[lazerin]

if i turn the top front fan round, won't that pull all the air away b4 it has a chance to reach the pci slots n stuff?

[JFettig]

and that will only circulate the air, itll get trapped inside the bezel and go down to the intake and recicle it... i suggest a top or side blowhole.. thats the only thing i can think of

[lazerin]

ok, so having dual fans on the psu is bad.
my pic of the setup is a bit misleading beccause the lower most intake fan is not actually facing the front of the case. its facing the side. does this make a difference?

[hellrazrblade]

i completely agree with maskedgeed. a top blowhole is what you need. the duct looks good. a 120mm fan in the top would make your pressure slightly positive which is good. if you think that would be too dangerous, you can cut the hole in the top center of the side panel, which is easily removed for cutting. my friend and i just cut some 120mm's in our cases. the holesaw and arbor were about $32 at home depot.

edit: i mounted the top fan outside of the case because it kept it out of the way of all of the psu cables as well as my tdk burner in the top slot.

Uh an intake fan *behind* a front bezel?? Assumed the fan would be clear. Funny concept of aircooling... sucking plastic.

[lazerin]

i've just changed my setup again. can you guys please check it?

[Quaky]

Why the two intake fans next to each other?

[lazerin]

i dunno. maybe its because it gives that false sense of power. it creates something like an orb.......maybe.:beer:

thats y im asking for opinions :)

so u reckon its not good?

[JFettig]

what did your cpu temps do like that??? i suggest you stick that one intake back in the bottom it doesnt help to stack fans...

whats the diff in temps with and without the duct??

[lazerin]

with the new setup, the temps r sky high again.
cpu:
idle 42c
load 49c
ambient:33c

when i had the duct and no other fans except the psu exhaust:
cpu:
idle 34c
load 37c
ambient:35c

then i added two intakes to the front, one on the the bottom, one midway up.
cpu:
idle 37c
load 45c
ambient 35c

then i took the duct off and turned the 80mm fan there into an exhaust:
cpu:
idle 40c
load 46c
ambient 24c

should i try stacking 2 80mm fans on the back n have on intake on the bottom front??

please help!:eh?:

[JFettig]

it looks like you need a blowhole somewere or take out one of the intake fans, and stacking fans doesnt work...

just take one of your intake fans out and see what it does..

[lazerin]

ok, i'll try that. can u plz explain y stacking fans doesnt work?

[hellrazrblade]

all that really happens when you stack fans is that the air is pushed a little further into the case.
lets say you have 2 40cfm fans stacked. (if they are different fans, it will actually decrease airflow) The first one pulls 40 cfm of cool air into the area between the fans. The second one takes that same 40cfm and moves it into the case. END PRODUCT: 40cfm of cool air in the case
lets say you have 1 40 cfm fan. It pulls 40cfm of cool air into your case. END PRODUCT: 40cfm of cool air in the case
did that help ya understand?

[lazerin]

yup! then i suppose this article is wrong?
http://www.tweakers.com.au/articles/cooling/casecooling_part1/page3.asp

[Nico3k]

yeah...
dont stack the fans on top of each other. spread them out. you might want to consider making fan holes on the top or the side of the case. that should fix your temp problem. :D

[hellrazrblade]

well, i guess it does help a little, you might get 42cfm instead of 40... but really, i tried it a couple of times and it just is not an effective way to go. you'd be better off without the second fan in the stack so that you can lower your noise a little if nothing else.

[lazerin]

dont worry, i've worked out good placement for all my fans :)

thx for the help guys,
Lazerin
