Fractal Define R6 / Top rad or front rad - Which config i best?

Hey guys,

 

I am going to be buying a gaming rig very soon, and I need some help with getting the most balanced/best airflow possible. I wanted to use Noctua fans because I've read they where both very efficient in cooling and at the same time quiet, which is semi-important to me. Also I've chosen to use a H150i PRO for my processor.

 

I have attached some demonstrations of the ways I was thinking could be the best solutions, obviously I have no idea what I am doing so maybe one of these 4 ways aren't even the best one, so I really hope you guys can help me out! ?

 

PS. Sorry for the size of the images and also I didn't know if it was possible to use 3 x 140mm fans in the front of the R6, if it is I would use that instead of 3 x 120mm fans.

Sorry, setup #1 but add a bottom fan like in #3.  It lowered my GPU temps a little.

 

I actually have mine like #3, due to shorter than expected AIO tubing.   Kyle did a good video on this.

It is NOT possible to use 3 140mm fans at the front, although it IS possible to use them at the top (I'm not sure about with a front mount rad too)

 

Setup 1 will give you the best possible CPU temps, but top mounting the rad would only theoretically raise they temps by a few degrees.

 

Setups 3 and 4 are probably best for an overall config (hard to say which is better, possibly #3 because in general three 140mm fans can move more air at the same RPM's than three 120mm fans)

From what I've read, top mounted rads was also the best and the norm. But I saw a YouTube video: 

In this YouTube video the front mounted rad completely changed the dynamics of the PC resulting in the CPU dropping 10*C, possibly because of the fans on top pulling out the air from the GPU a lot quicker, what do you guys take from this?

And also a big thank you for the help! ?

Rad at the top and add as many fans as you can.

 

#3 is looking like the best one.

I will be using the MSI RTX 2080 Ti Gaming X Trio btw, if that makes a difference in any way

Front mounting the rad means you're sucking in cold ambient air instead of the air inside your case that's been warmed by things like the GPU. This however means you're passing now warm air into your case where it will get sucked into your GPU, meaning it now has to cool itself with warmer air, resulting in higher GPU temps. Top mount is deemed "best" because for gaming, the GPU temps are generally more critical than the CPU temps

I see, and I guess the CPU will be plenty cool anyways with the H150i PRO. Thanks a lot for the help! Top mount it is ? One more question, the bottom fan shooting air into the case from bellow wont tunnel hot air from the power supply into the system? In regards to the power supply, should it draw in air from outside og shoot air out from inside the case?

The power supply is the Corsair HX750i

The psu fan should face downwards and act as an intake. The psu exhausts any heat it creates out the back and its airflow is isolated from the rest of the system.
