2 rads in the bottom of a Cosmos 2 case, Best fan positioning?

[Unframed]

Hi Guys

First, since I just joined the forum, Hello to everyone

I am about to build a new rig using the Cosmos 2 case and I am having a hard time figuring out what the best placement for the radiator fans would be.
I am going to use 2 Alphacool UT60 240mm together with GT fans in the bottom of the case.

I’ve made a couple of ideas (seen from above) in paint for how to do the placement but I’m not sure which one is the best or if there is another solution that is even better.

Push, Push/Pull and a front intake fan

Both rads using Pull and a front intake fan.
Would this cause a problem with the fans fighting for the air in the middle?

The 2 rads is going to cover some of the front intake fan. I have tried to illustrate how it is going to look like in the case. The air that the fan can push between the 2 rads is going to be limited, I am not sure if that will cause a problem? Or its fine since some fresh air is better than nothing?

The whole thing connected in Push, Pull/Push, Pull. Without a front intake fan.
The only problem I see with this is how I should mount the whole thing together. (Mount 4 fans to 1 rad and 2 fans to the other rad and then push the whole thing together as close as I can?)


A little bonus question.
Since there is not enough room for Push/Pull on the radiator in the roof. Will a Pull setup be best?
Or, would it be better pushing cold air from the outside through the rad and into the case?


Exited to be here and hope you guys are able to help me with my questions, thanks in advance.

All fans as pull and no intake fan.
Push/pull is a lot more noise for minimal temp benefit.

Neg is right about push pull though. I had Both my rads set to push.

I do the same.
The textbook method is pull tho,not what I do as I like to see the fans.

I always go with what looks best 99% of the time.

The CPU flow on Orca is reversed just because it looked better

Hi Guys and thanks for the answers.

Although you recommend Pull, I am thinking of going with Push like the two of you have done. I totally agree with you, it looks so much better seeing the fan from that side instead of seeing the side with the label and the wire.

Tom, I watched your videos and the rig looks awesome. I can’t quite see the fans you use besides the 2 in the front. How many fans have you used for the 2 radiators? and do you have any fans in the middle of the 2 rads?

Besides the SLI fitting have you secured the rads in any way?
