Push/pull fan question

+1 to the rad being to small

Thanks for all the input guys, I realize the physics of hot air rising and in the long run exhausting out the top does make more sense, if I have the front and side 230's as intake (and maybe a bottom intake if I can fit it) along with the rear 140mm and the 6 push/pull rad fans all exhausting that should create sufficient air flow and keep things cool enough. I think I'll give that a shot first and see how it goes.

You can try this and other way, it is all part of the fun.

For me: fresh air should come to the rad, not warm air from the case. That gives best temps from my experience.

Unfortunately I don't think I'll have time to try it both ways but we'll see how it goes.

Considering the Rad is on top , that makes your PSU on the bottom.
Here is what I'd do.
Flip the Rear case fan to Intake, keep the side 230mm to intake and front to intake as well.
Mount the bottom fan as intake too (get my theme here?) and then let the top fans be the only thing exausting.
You keep with the theme of hot air rising, you keep a positive pressure system which in turn will reduce dust, and you make that whole rad and case have a massive influx of air.
That, IMO, would be the best route to go.

Good luck,
ST

I know somebody who burned his mobo by putting too many fans into-the-case direction without adequate pushing air out as it created dead turbulence spots inside the Antec900 case. Seem you guys put too much trust in natural air raising process.

i have a hard time believing it had anything to do with positive case pressure sorry dude. and the process is called thermal dynamics and sorry to tell you but there is pretty much no way to keep the air in your case still because of the heat that it creates just a law of physics

Not still, but dead spots. You know how you hide from the wind behind the corner :)

Convection is highly overrated, in my own experience. If the GPU's are both air cooled, I'd probably have the rad exhausting, as long as the side panel case was intake, since it's in the best position to directly hit the GPU's/chipset. But if the GPU's were under water, I'd intake through the top, since the cooler air would then be affecting more components.

Considering the 3 Fans would be Exausting for the case on the Top, I doubt you would deal with that issue.
Airflow patterns are my niche you could say (considering I have insturments worth houses that depend on good airflow).
I think it would work perfectly.
It would also depend on the CFM difference of each Fan in the case, plus you would have the VC's moving air out as well.
I think it would work without an issue, this isn't convection I'm talking about, it is active cooling still.
