Twin Frozr III Airflow

post #1 of 35
Thread Starter 
I have pulled the trigger on two Twin Frozr III 6950´s and am wondering what would be the best way to configure the airflow in my case.

My CPU is on water with a 480 rad in the lower compartment..
I specifically chose the TWFIII to save money for Kepler which will later on go under water^^

Moving on.....

I have the Little Devil V8

With 3x140mm fans(1xrear, 1xupper front,1xlower front)
4x120mm fans(all in the top)


I have already heard multiple times the TWFIII exhausts a lot of hot air in the case so I figure it would be best to have more negative pressure in the case meaning more exhaust then intake.

But as you can see my options are rather limited.
The rear 140mm is most likely gonna be exhaust.
The big question is if I should use the 4x120mm in the top as exhaust or as intake?
And if I should additionally configure a fan right next to the cards to keep them cool.
But ultimatley concentrate on my case fans first^^

Here a picture of the case for better understanding:

Always put fans in the top as outtake, hot air rises.
Twin Frozr throws all of it's air into the case btw.

Definately have the top fans as exhaust. the back also as exhaust, and add a fan in the middle front as intake

Are you sure I should use ALL 4x120mm in the top as exhaust?
I thought maybe I could use the two left ones closer to the gpu´s as exhaust and the two right ones as intake.

Because if all four 120mm fans are exhaust the only intake fan would be a 140mm in the front which´s airflow is a little stopped by the Harddrives right in front of it.

If you really need to ask how to design your air flow...
does that mean you have not ever looked at any other air flow threads... ever?
They all say pretty much the same thing:

Intake low and in the front... exhaust up top and in the rear...

come on man!

*EDIT* If you have intakes and exhausts right next to eachother like that, all you are going to have is turbulence inside your case. and no real airflow.

This really is basic knowledge by the way.

You should google the word turbulence
The fans spin at 800 rpm lol.

The only problem with intake/outtake right next to each other is that they could negate each other but with such low rpm fans that should not be a problem.

And no man I wanted to create my own individual thread for this because the Little Devil differs a little from normal cases

You're right, because you have a "little devil" case, hot air goes down instead, so go ahead and change your top fans to intake.

not sure anything in the google of turbulence counters the point that putting your fans like that will create crappy airflow. because you will be pushing and pulling the air in the same vicinity. And your case is nothing special when it comes to air flow. sorry to burst your bubble.

oh my bad... i didn't realize that case broke the laws of thermal dynamics.

I meant it was different in terms of watercooling.
But you are right it is a magic case which not only defies the laws of physics it creates its ownThere is no hot air in a Little Devil Case so sry for opening that thread xD

No but seriously, you are right of course ...technically fans should not be placed together when operating in the opposite direction but with such low rpm fans it may work.

Still I won´t do it ....top= exhaust , rear = exhaust and front intake.

Only problem is that I only have 1x140mm intaking air.
Also that fan is placed before the hard drives which will also kill some airflow of it.
Which is why I thought I could place a fand behind the cage to enhance the front one a little.

And an extra one to blow directly on the two Twin Frozr III´s.

What do you think?
