Twin Frozr III Airflow - Page 3

post #21 of 35
Thread Starter 
Ok I know I have a watercooling case but just for the record^^
I am saving money on the gpu´s which is why I didn´t put them on water.
I am conserving money for Kepler which later WILL be on water and SLI

All my case fans are Bitfenix Spectre fans.

Here some pictures of my case:http://www.overclock.net/computer-ca...tion-help.html

-------------------------------------------------------------------------------
Ok for all who are new and have recently joined I wil post the pic again to clarify the air flow conditions.



I have 2x140mm (1xrear, 1xfront)
4x120mm (all in the top)
options.

The Twin Frozr´s will be installed with a lot of spacing between them so both cards can breathe sufficiently.

Since the cards will exhaust a lot into the case I think most of the air will rise to the rear exhaust fan which is why I will install it as exhaust.
The rest of the exhaust air that can´t be exfiltrated by the rear fan should be able to be exhausted by the top 2x120mm right under the gpus ...so I am thinking to also install them as exhaust.

That only leaves the right 2x120mm fans in the top... I know chances are that if I mount these as intake all the cool air could immediately be sucked out again by the left 2x120mm fans which are mounted as exhaust but for now I would like to let this stand like that.

At last the 140mm in the fron also exhaust of course.



So we have 1x140mm rear exhaust , 2x120mm left exhaust , 2x120mm right intake , 1x140mm front intake.

Here a picture of my idea:

If you have figured a better way please post

And please calculate possible negation of the top fans ...but I am not sure if it is certain they will do that.

Here's my plan for you. See the attached thumbnail I've omitted the bottom part of your case, since it's basically separate. Basically, move your PSU to the top. Oh crap, is your PSU in that bottom section? If so, ignore that part of my picture. Buy a Lian Li or other 5.25 in. bay device that is made to hold 3 or 4 3.5 in. HDDs and put a 120 mm fan in the front of that. That will give you another intake. Use the front two top holes as intakes. Block off the rear two. Add another 120 to the bottom pulling air up unless that's actually hot air, then ignore it. You could have up to 5 fans pushing air in. 2 in the front, 2 on top, and 1 on the bottom. Remove all the brackets on the back. You'll have positive air pressure pushing the hot air from front to back. Don't worry about convection and heat rising. The effect is not going to be that pronounced with the airflow that you'll have. ehume would recommend using no rear exhaust fan and in the drawing, I've shown it as optional. ehume would tell you to cut the fan grill completely out, but that may or may not help you since you don't have a cpu heatsink with fans.

The only question is if it is ok to run 2 of the 4x120mm in the top as exhaust and the other two as intake.
Is that possible with 800RPM fans?
Would that negate the airflow?
Or would it work?

I think you'd be wasting your time with two as intake and two as exhaust. They would negate each other. You'd be creating a current of air that may cool the cpu area, but you're already watercooled. Also, an 800 rpm 120 mm is a waste of time in that application. That would be very little airflow. Blocking those back two holes will help direct airflow out the back of the case. Think about, the best airflow scenario is positive pressure airflow in a straight line front to back. The closer you get to that, the better.

I don´t like the idea of blocking out 2x fan spaces.
I prefer to have more exhaust capability then direction of airflow.

Also I don´t think the 2x120mm exhaust and 2x120mm intake idea in the top is so dumb.
As you said the air flows in a direction.
Imagine it like a barrel.
I don´t think two fans next to each other would negate each´s airflow because the exhaust and intake in a straight direction.

The only way they could negate each other would be one would sit on the other one.
Also the two intake fans at the top are there to take cool air into the case ..it doesn´t matter that they are not hitting the gpu´s directly.
Air is a gas ...and gas expands...and eventually the cool air will expand to a point in which it will hit the gpus.

So still I stand by that idea:



If somebody would like to disprove me on that please rise!

Well, you have an idea in your head and that's what you'll do. Don't bother shopping for any more advice. For the record, I've done this in my own case and I still stand by what I said. Unless you're a thermodynamics scholar, I wouldn't be so confident. Only you can prove which way is better by testing yourself. Just remember that in a static situation, cold air moves towards warm air. Good luck!

i'm no expert, but since pc airflow is always low front to top back I'd do the following:
-put fan in front as intake
-put 2 fans on the top as exhaust
-put radiator on back

There will go some hot air from your 6950's in the radiator, but since hot air travels up, the two fans on the will suck out more hot air

you could also exclude your radiator from the case's airflow and put it next to it, so the case only cools your gpu's and mobo

EDIT: you have four holes on top:
-put your radiator on the first 2 as exhaust, itll suck up the cool air from your front intake fan.
-on the last two holes place outtake fans
-on the back outtake

you could also make your radiator an intake fan, the hot air will be sucked out immidiatly by the exhuast fans.

As shown on your epic drawing the top blue intake would be the spot where you place your radiator

So you think all top fans as exhaust + rear exhaust + front intake right?

I think you are right though
