2x AIO dilemma, positioning.

[Pichulec]

Hi. I am upgrading my case to get better colling for my 2080Ti.

 

At the moment i have Nzxt phantom 630 + Kraken x53 for cpu with 2x140 fans mounted at the top as exhaust and Kraken x41 for 2080Ti at the rear also as exhaust. I have two fans blowing fresh air from the front 2x140mm.

 

I am changing case to accomodate bigger aio for 2080ti.

 

So i bought Raijintek Zofos Evo RGB Full Tower and i am replacing Kraken X41 with Kraken x61 (i am using G10 bracket).

 

Now the question is. Where to install aio for gpu. I want the gpu to have lowest temps as that will stop it from thermal throttling. I plan to install cpu aio on the top as exhaust, cpu temps are not that important, it wont throttle. Now option for gpu aio is front as intake or side as exhaust + 2 fans intaking air to the case. I have total of 7 fans. 4x for rads and 3 extra. If i put gpu rad on the side and get 2 fans blowing air from the front, how the airflow will look like??  I would like to avoid putting gpu aio as intake as the air coming out will get quite hot, that gpu can heat up the atmosphere quite a lot. So i want best conditions for gpu and ok for cpu. I am almost decided to put gpu aio to the side as exhaust but i am worrying about 2x front fans being to close to it and disturbing airflow. Please help

So you are only cooling the GPU chip, not the other chips on your graphics card?

If yes, the temperature limit of the other chips can limit your graphics card's performance.

 

The coolest configuration you can do is probably this:
Front intake fans, side exhaust for graphics card radiator, top exhaust for CPU radiator and rear intake.
This way the graphics card gets all the cool air from the front intake and the case inside doesn't heat up becaust the graphics card heat is exhausted.
The rear exhaust takes in cool air for the CPU. But with this configuration your rear fan will have to spin faster or you will have negative pressure, which can lead to more dust.

I have preserved the back plates for gpu, so vrms and memory are also cooled.

Memory is spread around the chip near where your aio is placed so backplate cooling seems a bit too hopeful. There are also most likely more vrm components that need active cooling than just those that sit under the g10 fan.

Whole thing is cooled, full top and back plate preserved.

what about the back mosfit?

Everything is cooled, how many times i need to repeat?

As for the rad mounting options, the side intake seems to be less restrictive than the front.

Small update. Installed GPU rad as intake, cpu rad as exhaust + 1x exhaust fan on the back. Temps are: Gpu 53C max in gaming, cpu 50-60C in gaming. RTX2080Ti stays on 2010Mhz all the time. In max heat stress test for cpu in prime95, cpu hits 84C. I only use silent profile for both krakens so a lot can be improved by speeding up the fans. I am happy with the results.
