Cooling Lian Li A05N case fan config - Do I have it right?

Hi all,

I've got a great system I recently built and placed in a Lian Li A05N, which so far I love. I've recently purchased the top cover for the A05N with a 140mm fan and am thinking about re-doing all of the other fans in my case as well. Just to give you an idea of my thermals, here's my system.

Asus P6T Deluxe v2
Intel i7-930
Noctua NH-U9B SE2 (push pull config)
Radeon 5850 1gb
Seasonic X650 PSU
6gb Corsair DDR3 1600 RAM
Samsung SpinPoint F3 1TB

Here's what I'm thinking about doing to my case. Currently the rear-fan is doing intake and the front fan is doing exhaust. This doesn't seem to work for my setup very well. I was thinking of replacing both front and rear fans with Noctua NF-S12B FLX 120mm fans set to be intakes since they have really high air-flow and placing a Noctua NF-P14 FLX 140mm fan on the top to exhaust the hot air. In addition, currently my CPU cooler is setup West-East in a push/pull config pushing air towards the front of the case.

So here's my question:
1) Should I setup my cooler North-South with the fans blowing onto the bottom of my video card?
2) Should I go with the Noctua NF-S12B FLX fans for their high airflow, or would my setup benefit more from going with two Noctua NF-P12-1300 120mm fans for their high static pressure?

Here's a diagram of my proposed setup...


Finally, this is more of a education thing for me since I don't know a great deal. What is more important in a fan setup? Airflow? Static Pressure? A mix? How should the two interact? What balance should I be striking? Any help here would be greatly appreciated!

 

i would go for what ever set works for your every one has different hardware and cases so the best thing to do is swap arond the fans and see what that does to the temps that is what i recomend

instead of buying noctua fans i recomend buying scythe Gentle Typhoon they are better and a bit cheap so they are the best fans on the market

 

Both of those Noctua fan are damn near useless. I have one of each on my TRUE, and although they are quiet, they move next to no air, and the P series still has really low air pressure. i got a set of the 1850 RPM Gentle Typhoons and although they are marginally louder (and by that I mean your GPU will still produce alot more noise) but they shift loads more air at a much higher pressure. Go for 2 of those and a good fan controller, then you can turn them down in the winter and up in the summer for a cooling boost

 

I'll have to check out two Gentle Typhoons for my front and rear intakes. Does anyone have a recommendation for 140mm fans? I'll have to experiment tonight with rotating my CPU cooler North-South and seeing if that improves cooling. My thought is that it will since it will have both push/pull coolers moving air through it, as well as the rear intake blowing directly across it, and my GPU will benefit from the air being directed against its bottom.

Has anyone heard anything about or actually used Noctua's 140mm fan offering? I like Noctua as a quiet company and that's why I go directly to them, but I know next to nothing about fans so please, educate me!

Thanks,
Ramzie

 

CPC did a whole review of about 100 fans, it's on BT too, just look in the review section under cooling. They found that 90% for 140mm are 50% worse that a 120mm, so I'd say stick to 120mm
