Maximum Airflow for my new case?

Brachra2055 · Feb 22, 2014

So im getting a new case, and along with it i got 3 new case fans, a new PSU and a new Heatsink.
the heatsink blows down or up instead of outwards, and i cant quite figure out what my best bet for airflow would be..

Here are two poorly drawn examples of my case with where the fans would be.

The first
(without airflow, just positioning)

The Second (My guess at what the best would be)

Any help on this would be great.
im just worried that the PSU blowing on the GPU is going to be an issue as well, but the PSU has to go on the bottom of the case.

The power supply typically intakes air in the bottom, and vents it out the back of the PSU.
As for the rest, you always want more positive air flow compared to negative. So equal-more intakes compared to exhaust.
What case do you have? It might be better to have a bottom and front intake, and a rear/top exhaust etc.

Brachra2055 · Feb 22, 2014

Well, the PSU has a 140MM fan that can either blow Up, or into the case. it dosent appear to have any sort of fan that vents out the back like most i have owned. so i dont think thats a choice.

As for the case, its an Elite 431

Gam3r01 · Feb 22, 2014

Mine has the same type of fan, and just a mesh across the back. If it dosent have that you can just point the fan down, and it will do fine.
(I had the ELITE 430, and just upgraded to the Carbide 300R this week)
Using a front and bottom intake, and then a top and rear exhaust would be the best bet. Equal air flow across the case and wont fight anything.

Brachra2055 · Feb 22, 2014

How can i do front AND bottom intake? There only other fan mount is at the top in the back above the PSU

Gam3r01 · Feb 22, 2014

If you look at the bottom of the case, in between the hard drive bays and the power supply there is a 120mm/80mm mounting point.

Brachra2055 · Feb 22, 2014

Okay, i ese whta you mean on the bottom. That is out of the question. where my case has to sit, it wouldnt intake any air like that

Gam3r01 · Feb 22, 2014

This case? http://www.coolermaster.com/case/mid-tower/elite-431/

Edit, ah well it has a few cm clearance with the legs installed, if that wouldnt work, I would run a front intake, and a rear+top exhaust. Having 1 more exhaust than intake wouldnt be bad.

Brachra2055 · Feb 22, 2014

Unless you think that 1inch between the table and the case is enough air for intake..

2nd edit.

Okay so Front In, rear back out, two top out, and then the PSU would just do its thing Pulling in and blowing upwards towards the exhaust? I assume then to put the Heatsink blowing up on the top exhaust ports aye?

Gam3r01 · Feb 22, 2014

It was with my case, which is the same height.

Brachra2055 · Feb 22, 2014

like this?

Gam3r01 · Feb 22, 2014

Yeah like that. That was the setup I used and it was the best I found (I tried 4 different ways)

Brachra2055 · Feb 22, 2014

I'll use that setup than

Thank you very much sir

Gam3r01 · Feb 22, 2014

No problem, I liked that case other than the lack of cable management

Brachra2055 · Feb 22, 2014

one reason i got this
http://www.newegg.com/Product/Product.aspx?Item=N82E16817116024
i figured it might help a little

Gam3r01 · Feb 22, 2014

Yeah that will. This was my setup (with a 760 instead of the 7750, old pics, and then my new rig) http://imgur.com/a/dMmQc#9

Also that PSU will intake though that fan, and vent out the back, so you can face it down.

Brachra2055 · Feb 22, 2014

Wait it intakes through the fan? but still, wouldnt intake from that 1/8th of an inch between fan and bottom of case still be an issue?

Gam3r01 · Feb 22, 2014

Yeah it intakes with it, and there is a vent on the bottom of the case for the PSU as well, so it still has plenty of airflow.

Brachra2055 · Feb 22, 2014

Final picture i promise lol. A bit OCD, have to be very clear...

Purple represents facing, and of course blue represents flow.

I got it down?

Gam3r01 · Feb 22, 2014

Yeah thats right (You will only have one top fan I believe, since you have 4)

Brachra2055 · Feb 22, 2014

Ah thats right... Case came with front,
id have one on bottom, 1 top, 1 back.

ah well, wont look as pretty as i wanted but itll do

Gam3r01 · Feb 22, 2014

Yeah itll do, if they are LED fans (which I hope they are

) The case will be lit up nice from all sides.

Brachra2055 · Feb 22, 2014

Oh they definitely are, im trying something new and mixing it up, Red LED on heatsink, blue front, 3 greens for the mounted. Hoping it will look cool.

I just realized though i dont know how my new HS works with airflow
http://www.newegg.com/Product/Product.aspx?Item=N82E16835118075

does it blow the direction its facing? or does it intake from direction its facing?...

Gam3r01 · Feb 22, 2014

That should look pretty cool!

As for that cooler, all CPU fans I have seen suck air over the motor they attach to. Example, my fans blow air across the braces that hold the motor.

Brachra2055 · Feb 22, 2014

Okay so the side with the logo (what i call the front), is sucking? and the side opposite the logo should be facing the top of the case then aye? Also i apologize for all these questions but im sick of half-assing my setups, and you seem to be answering over and over so it must not be bothering you too much

Maximum Airflow for my new case?
