Need Air flow suggestions

Hi OCUK!

I was wondering what would be the best air flow through my system.

Here's my current setup:

-PSU is downward facing
-GFX IN-TAKES air
-Green at the back is the Antec 920 cooler, sucking air OUT via the radiator
-Green at the top is currently a Corsair AF120 sucking air OUT of the case, however I will be changing that to a AF140 (120mm vs 140mm, I want 140mm as it fills the gaps in the case)
-2x Red at the front are the Fractal R2 Silent ones sucking air IN
-Motherboard is the Sabertooth Z77 that has two mini fans on it, that ventilate the air in that sort of fashion - to the side and to the bottom.
-Side Panel hole is CLOSED

Here's how it looks like:



My questions are:
-Do I need to suck air OUT or IN from the top - what would you suggest? I feel OUT is better as heat rises and it wouldn't then conflict with the Antec 920
-Should I add ANOTHER fan by the GFX - this is where the side panel is, and where there is no fan there currently (closed)
I was thinking of another AF140 to IN TAKE air into the case, so that the GFX gets a little bit of help.


here's my actual system look at the moment:

Just in case you're confused of the direction of the picture:
The right side is the FRONT
The top side is the TOP
The left side is the BACK
The bottom side is the BOTTOM

Here's the TOP - where the AF120 is in at the moment.

Generally I setup my cases with:

Front: IN
Bottom: IN
Rear: OUT
Top: OUT

I try my best to get an even amount of airflow in as out, make sure you don't have more airflow in than out as this creates 'floating' hot air. So keep your current setup but add an extra in the bottom of the case.

Thanks, but i can't do anything with the bottom. They are just vents nothing more.
I can however put one on the lower bottom side panel. But that's exactly where the gfx is.

Bottom vent in your picture has mounts in it. :rolleyes:

Also, your AX750 PSU is sucking air in from bottom unless you have one like no other.

I suggest turning top fan to intake and removing unused PCI slot covers. This will help supply cool air to radiator fan and vent GPU heat out back. ;)

Right for the vent - yes it has - but I can't fit a fan in there - the PSU cables are in the way + there is a carpet - so it won't really help.

As for PSU direction - my bad

Removing the PCU slot sleeves -> bad idea I need it there, to help prevent dust getting in there as my PC is picking up a lot of dust from building work outside...

And why intake rather than out - considering the fan of the antec is taking out?
I'm curious
 
iirc, with closed looped coolers, u get better results with cool air blowing into the rad from the rear of the case, then the top case fan will exhaust the hot air for u.

sorry I'm a little confused with that.
Your saying blow air in from the back...and blow air out from the top?

If so - then I can't really do that due to the antec.
 
sorry what i meant was, to have both the fans on the antec sucking in air from rear of case. in push/pull
the theoty is, as they are sucking in cooler air from outside the case, the antec will run cooler, than if there were set up to suck in warm air from inside the case

ah well - antec + every review don't push pull....so unfortunately I'll be sticking to my understand of that one, in going OUT the case.

Well if there is carpet how can your PSU get air? :D

If your top was an intake your case would have positive pressure.. That means air would flow out PCI slots, not in. :p

Intake (with filter) rather than out to make sure you have positive pressure in case so air will be flowing out of PCI slots, bottom and cooler and not sucking air in (with dust in it) as it tries to replace all the air exhaust fans are sucking out.

In most cases with good intake fans in the right places you don't need exhaust fans. The intake fans blow air into case and air flows out of case wherever it can go... vents, holes, etc. :D
 
Have you tried placing the kuhler at the frot of the case(if it reaches) pulling in cold air from the outside then set up the rear and top fans as extract.

I have discovered this gives me the best temps inside my antec 300 case. High cfm fans at the rear and top along with the slower moving pressure fans at the front on the kuhler and the spare mount you'd have.

Everyone has gave suggestions yet you have shot them down. Why don't you try different configurations yourself?

Not really...
Had one that says to put a fan at the bottom. Which i can't do.

Had another tell me to push pull the antec, but it's not designed like that, and isn't documented by anyone to do push pulling.

Had another to invert my top fan, but with no explanation towards it conflicting with my antec or not, considering they are right next to each other.
Finally, got told to get the dust covers off, but with the building work going on, that's the worst idea for me.

People have just ignored my two questions i posted in the op.
 
Your questions have been answered repeatedly by many members. I for one am about at the end of my lead with all your questions and apparent inability to understand simple English explanations. You replies often sound ignorant and rude. So maybe you should be the one who backs off and looks at what has been said. We are trying to help.

Talk about kicking gift horses in the mouth!:(

You do realise I was the FIRST person to give you advice right? *Facepalm*

I have given you suggestions (Along with other members) now get off your ass and try them out then decide for yourself. Monitor the temps and keep what is best, it's your computer so put some effort in yourself.

I'm out.

Gotta love the community.
Please show me the answers to my questions + explanations - I would love to see them. As for the time being I'm just seeing 2 people flaming me for asking the questions I had already asked in the beginning...

I think your questions have been answered quite comprehensively.

What I do not see is what your temps are, which ideas you have tried and what temps you got doing it.

Even if you think some of the sugestions are a bit lame, the people are trying to help you which you should be grateful for.

Looking at your setup it does not strike me as a difficult challenge to keep cool so try out some of the ideas and post how you get on.
