I have a Cooler Master Cosmos 700p.  I'm waiting for my 3080ti ftw ultra.   There is a top 360 aio on top.  I would like to get the hybrid kit for the the card but was wondering.
 
CPU AIO on top or front.
GPU AIO on top or front.  
 
 

Tubes coming from the bottom?  Cause I do have 2 mechanical hard drives there. 

Problem it's the video card so in order for the pump which is in the card to be lower than the inlet it would be towards the bottom of the case.

What? Card goes in it's normal spot, radiator mounted at the top, makes the pump lower then inlet.

With a front mounted AIO cooler the tubes do not have to be on the bottom, that's a misconception. As long as the pump is lower than the radiator inlet, air will not get trapped in the pump. If some air is in the pump after installation, it will work its way out.

I was under the impression that tubes being at the bottom is not because of air in the pump but because less liquid to pull in from the top of the rad as the air would collect there.

I think for this case, if it can reach, CPU AIO at the front intaking and GPU AIO at the top exhausting.  Tubes up is probably the only way this will work unfortunately but is still a lot better of an alternative to say GPU rad at the front intaking with tubes down.

^Bingo. This is the way.
 
I can tell you from personal experience that if you mount your 3080ti radiator as an intake, your CPU will start running WAY too hot (among everything else in the case). You're much better off running the CPU radiator as a front intake and the GPU as a top exhaust.

Both intake for the win.. heat will be pushed out all the openings of the case anyways.. and 0 dust problems.

I'm on an auto notify to get a 2nd cooler bracket for the cosmos 700p to fit 3x 120mm fans to the bottom.  I'll probably use that as an exhaust, hopefully the wood floor doesn't get messed up lol.

 



Honestly, if you can install fans at the bottom then I would use those 3 x 120mm fans as intake and then exhaust both the GPU and CPU aios.  That's what I do with mine.  




is that the only way you tried it?  cause if it's like only a 5 degree drop then i wouldn't worry.  I've had people on here say both gpu and cpu aio set as intake.  
 
I see my cpu coolent a 30 and the cpu temp at 40.
