AIRFLOW question: what is best?

[i_build_nanosuits]

So, i ordered a 240mm AIO this morning for my CPU and i plan on instaling it in my Enermax Ostrog GT case

(this question could belong to watercooling section as well or maybe even case i don't know...since it's about airflow i decided to ask here)

My case has dual 140mm intake fans at the front (middle HDD rack removed to improve airflow over graphics card), and it also has a 120mm exaust fan...and room to mount the 240mm rad in the top of the case.

 

I guess my question is: Should i use the AIO cooler as INTAKE or EXAUST? basicaly i have made two drawings that would show the airflow which one would you think is best...i guess using the AIO as intake for fresh air through it would give better temperatures for the CPU but would a single 120mm fan be enough exaust (positive pressure is good to keep dust out i know that but will it be too much?)

 

OPTION A:

 

 

 

OPTION B:

 

So what would you do? thanks in advance!

[ELSknutson]

option A

[Goussy]

I'd go with option A

Edit: I feel that if you go with b then there be some hot air dormant in the middle of the case

Option A for sure.

Option A for myself, can't tell you what to do

Just seems to make more sense...

Besides, you can always test it for one week, swap for another week...and note your averages...

/and let us know

Great, and do you guys think a single 120mm exaust will be enough? granted it does spin somewhat fast (can be adjusted in the uefi) and that fan does seem to move quite a bit of air...i'm using the system in config A right now with an hyper 212 cpu cooler blowing through this exaust 120mm fan and it does blow hot air out the back...

If the top isn't filtered then I would not choose A.

yeah you will probably be just fine with one.

What would it matter if the top is filtered or not? It's not like he's using it as an intake.

Similar config (cept my top isn't populated, but has a thick 240mm mesh grill to keep some pressure) PC sits on my desk to the right (70cm away), rear towards me, front facing away.

Rear exhaust is closest to my ears. (I did also set it slightly aggressive to do expel heat faster)

 

The rear does take a lot of my 290's heat out. GPU during gaming is around 70*c while CPU @ 58*c

Rear fan does a good job, you may have to spin it a little faster,.. thats up to you.

I'm sure your gunna experiment... if you can build nanosuits, you can do this /bazinga

it is not filtered indeed...i guess i could make a filter for it with something?

[decripple]

I would do option A because I have used that same configuration on a corsair Obsidian 650D case (very similar ventilation layout) and I will also say you probably want to filter the top vents with something mesh maybe Thermaltake Matrix fan filters or the like.

in configuration A the AIO would indeed be used as an air intake...

[Nup]

Am i the only one inclined to say option B.... 

[Goussy]

coffee filter hehehehe

[i_build_nanosuits]

coffee filter hehehehe

i was thinking more like women pantyhose or something like that that i could cut a piece and stuck between the screwed rad and the case...

Option A sure looks like it...

Pantyhose is a good alternative

[i_build_nanosuits]

Pantyhose is a good alternative

great! that's what i will do then...i will mount the rad on top and use it as intake, that way the CPU gets fresh air...i'll set the fans in pull mode so that fresh air is pulled through the rad...and will make filter intake with some black pantyhose that i will cut and stick in between the rad and the case then i'll screw all that togheter nicely...thanks a lot guys!

oshit my bad.
