Need help with airflow for 900D

[riad]

Can someone let me know what direction i should have my fans facing for positive airflow to keep as much dust out of my case as possible? In the professionally illustrated diagram it shows the layout of my case with 2 NZXT g10 GPU brackets. Let me know what i can do to improve airflow and positive pressure, thanks in advance.

All intake except rear exhaust

 

H55's blowing from front towards back

The H55s are going to be blowing very hot air, you want then going away from your GPU.  Is it possible to place them in the bottom compartment by chance?  Maybe buy a Kraken X31/X41 to give you longer tubes to work with, especially in a full tower case.

As superficial as this sounds, i'm willing to sacrifice a few degrees for the sake of aesthetics.  If nothing can really be done, i would opt for your solution. Even with a X31 it won't be able to mount on my front intake slots Sometimes i wish my 900D wasn't this big

The thing that really scares me if you were to have the H55s blowing onto your GPU, is the VRM temperatures.  I'm not kidding when I say that the air coming from the GPU's radiator is hot.  #1 You don't want that air blowing onto your GPUs. #2, you want that hot air being expunged from your case in the fastest possible way.

The only other option is to mount 1 h55 at the top exhaust and the 2nd h55 at the bottom side both as exhausts, aesthetically it will look horrible but like you said the temps will be alot better. Just curious, just how hot would the VRM even reach? I'm just wondering if it will really be that terrible, if it is i'll have no choice but to do as i just posted.

I wouldn't want to risk it.  On the G10 Owner's Club, one guy was saying his VRMs went as high as 110C on his stock  Asus 780Ti Matrix Cooler, and dropped down to 78C when he did the G10 mod.  So it looks like the VRMs have a pretty high temperature limit, but I wouldn't want to risk it.  The air that is being pushed out of the radiator attached to the GPU is hot.  When I play BF4 for an extended period of time, the air is very hot to the touch and I wouldn't want that blowing over my VRMs.

 

I think your best bet is to buy the X31s so that you have the extra tube length in case you need it.  Try different placements to find one that works for you.

i wouldn't mind buying the x31 but the problem is amazon doesn't have any of them and ebay has them for $89.00. I'd rather stick with the H55 for $59. and the 12 inch tube will be enough to mount in those spots, thanks again!

You can't buy from Newegg?

O shit, i didn't see that on ebay, i'll check to see if i can mount it in the front of the case, if i can't i don't see the sense in getting them over the G55. Thanks for the link though, at least now i have the option.

I also was going to get an H55, even though I knew I was going to mount it in the rear and didn't need the full 16 inches of tubing, but because I have a full tower case, I wanted the freedom to place it as I want which comes with the 16 inches.  The performance is also supposed to be slightly better with the X31 over the H55, but the cable length was the real attraction to me.

Why are you stuffing the truly massive 900D with a bunch of AIO's anyway. Wouldn't a custom loop be nicer?

It would be but at the moment i can't afford a full custom loop for the 900D and besides that, i don't want my Titan's running at 80+. Eventually i will do this case justice and build a custom loop but for now this will have to do. It's only gonna cost me $300 to cool both cards anyhow. A full loop will range me from $500 - $900 ( Gpus + Cpu )
