help me with airflow in my case

[QueBert]

Tiny ass EVGA Hadron, right now it has the 2 stock 120's on top blowing out, and I have my Cooler Master TX3 mounted horizontally with the fan facing up. There's not enough room on the bottom side between the heat sink my video card to mount it there.

I'm going to be ordering 2 120mm fans, I'm also looking at some 92mm/14mm Noctua fans for my heat sink and 2 of their 120mm flx for the top. I'm taking a guess that with them being thinner than the stock 92mm fan on the heatsink I could mount 1 on each side. Here's my questions:

Would it be better to mount the heatsink vertical and have the fans facing the front and the back of the case? I'm not even sure if it'll fit that way, but if it will would it be better? Also, should I switch the top fans to intake? The PSU has some funky tiny 40mm fan on the bottom blowing out of the case's bottom mesh. I don't think it can posibly be doing much though.

I would keep the exhaust to the back so you get the max air flow(otherwise they may kind of cancel each other out and not cool as well depending on the orientation off all your internals), and if you think your processor will get really hot, switch the top fan to intake BUT you'll have to clean out your case much more often if you do this.

You are probably fine with horizontal

:whiste: I would suggest an M134, that will most certainly help you with regard to the airflow in your chassis. :whiste:

wave the white flag.. give up.... game overs man game overs... lol..

it wont matter honestly... Anyone who says it does... has problems building because it means warm air is getting stuck inside your build, and flipping it fixed it.
Or your cable management is so horrible, you even beat spiders at how its laid out.

It only matters the most in tower sinks and deep roof cases because, b4 cases had a top vent... the hot air would vent up and cause a air bubble to form.
This would hinder the heat sinks overall performance because the backwash would feed back into the intake.

So it doesnt matter what direction u have in your tiny case.. because the fans inside it already flip the entire vol. every 10 seconds or so from my guessimation, so u wont have any kind of heat gradient inside your case.
