Bitfenix Prodigy aiflow advice (with picture)

Hello all,

 

I'm in the planning stages for a new build and this time I've decided to go small, since I've had enough with big, bulky enclosures.

 

So I've chosen the Bitfenix Prodigy.

 

Since it's a small case, well thought airflow is a must. I've read some articles, including OCN Dave's Air Cooling Guide, saw some Youtube movies.

 

I've reached the conclusion that a positive pressure cooling scheme would be best, since it helps keep dust at bay. However, the case being so small I thought I' ask for your advice.

 

I've quickly sketched a picture below on how I plan to do it.

Quick spec sheet (heat generators only):

CPU: i7 4790K

GPU: Saphire Radeon r9 290 Tri-x

PSU: don't know yet, something around 750W, fan on bottom, most probably

 

I'm thinking to use:

Noctua NF-F12 Industrial PPC 3000 PWM 120mm for the case intake

Something with high CFM for the exhaust. It should'n need static pressure, since it's an exhaust, right?

Corsair H100i for the CPU (maybe in a push/pull?)

 

I tried to represent how the air would flow in the case and the way I see it would heat up. The only thing I didn't represent is the airflow from the GPU.

So, any opinions?

 

Thanks!

I have always avoided top mounted fans due to dust falling inside my previous cases.

But it will be interesting to see how well a filtered top intake will perform and how easy it will be to maintain.

The NF-F12 at 1500RPM is already quite loud

The industrial F12 at 2000rpm is twice as loud as the 1500rpm version

The industrial F12 at 3000rpm is more than twice as loud as the 2000rpm version

I thought that being able to connect them to the motherboard fan controls I can control the speed through the motherboard PWM application. The 3000rpm could be the loudest, but at least, if needed, it could deliver the airflow needed.
 
@whipcreambeast: the top of the prodigy is filtered.

LE: sorry, didn't see you already said that.. :)
 

If you really want to go with the industrial noctuas you probably should go with the 2000rpm version

 

I thought of them because they'd be more resistant to dust, being intake fans.

Somebody on another forum suggested I use this airflow scheme. Is this one better?

Get the black version - for some reason that is the only one with a fully ventilated front, per SPCR's build. Also try to get the top front and rear lined up for direct action. if you go with a top rad, then have it exhaust out, but also use the rear as exhaust!

They may very well be aligned, this is a Photoshop comp.

If I use the back also as an exhaust it would't be a positive pressure environment.

It would still be OK as positive. You would have plenty of filtered intake in the front with good flow through the back. The top rad is not free flowing and so in combination with a single rear exhaust would not be strong enough to overcome front intake to pull air from slats on the sides or bottom.

A fast calculation shows that we have 2 fans as intake (2xfront) and three as exhaust (2xCPU, 1xback), roughly at the same CFM. How can you say it would still be a positive pressure environment is beyond me.

 

In the meantime I have decided to go with regular NF-F12s, as industrial ones would be overkill.

I might end up with this fan configuration in my mini-ITX Z97 build.

 

I have a BitFenix Prodigy black, and in the front I'm using a BitFenix Spectre Pro 230mm red led fan, in the back a BitFenix Spectre Pro 140mm red led fan, and for my Corsair H100i I might end up using 2x Noctua NF-F12 industrialPPC-3000 PWM.

 

But I have 2x BitFenix Spectre Pro 120mm red led fans + 2x BitFenix Spectre 120mm PWM red led fans + 4x BitFenix Spectre 120mm red led fans, to test them all on the Corsair H100i and keep the ones with best performance and lowest noise.

it is beyond me why you can't realize that CFM will be greatly impacted by the radiator placed right in the face of those top fans - as radiators are designed to catch as much air as possible. 

 

enjoy your bitfenix product.
