Looking for advice for dual aio setup

[Jon88]

Hi all, I've spent the past few days looking this up but i can't find anything specifically similar to my situation.

I'm using a meshify 3 standard case, not XL, badly needs a mid size inbetween but it is what it is.

The case only allows a 280 aio at the top and a 360 aio at the front, after this i really just have a rear fan slot.

Cpu is 280 arctic freezer 3 pro cooling a 9550x3d, it's mounted top
Gpu is a 5080 aorus waterforce extreme (aio not wb) on a 360, mounted front.

I have a noctua af-12 for the rear

Option 1. I'm intending to go both intakes for the aios with the rear as exhaust.

Option 2. I could swap rear to be intake and have both aios be exhausts

Option 3. Rear exhaust, top cpu 280 exhaust and front 360 gpu intake.

Option 4. Both intake and no rear exhaust.

Any input would be much appreciated as any info i have found in the days i've spent searching have conflicting results and usually include extra intake or exhaust fan options in sides or bottom which i don't have with this case.

Thanks,

GPU will generate a lot of heat and having that rad blow into the case will make it toasty in there pretty quickly. You would need to draw in more cooler air than is generated by the GPU, or exhaust that heat into the ambient air outside of the case.

Sorry a little late on this but I run dual AIO.

I put my Liquid Freezer 3 pro 360mm on the bottom of my case. It's sat on 3x 15mm x 120mm artic fans and it's being used for intake.
I also have the Astral LC RTX 5090 with 360mm AIO and I placed that in the top of my case as an exhaust.

It works extremely well and everything runs very cool. The rest of my fan layouts are as follows.
2x 120mm Fans on the front and 2x 140mm fans on the Motherboard side of the front back of the case. These are all intake.
I then also have a 120mm fan on the rear as an exhaust.

I currently run:
Ultra 9 285k @5.4ghz (30c idol and around 65c under load)
48GB Corsair vengence DDR5 @8400MHz (consistently running around 30-40c)
Asus ROG Astral LC RTX5090 with 360 AIO (idols around 30c and averages between 60-65c under load) I will add I also overclocked this.

The rest of my build is:
Asus Maximus z890 Apex.
Phanteks revolt titanium 1600w.
Cablemod + replaced the 16pin splitter for 16pin to 16pin for the GPU.
Montech king 95 pro (modded the front to take 2 extra 120mm fans).

My whole system runs very quick and very cool. Having the GPU as exhaust helps keep good airflow throughout your case. You also need to look at where the pump is situated on the AIOs. You always want your pump below your radiator to stop it producing air bubbles. Will work fine short term but risks burning out over time. I found my GPU pump was on my GPU and the pump on my CPU was in the radiator itself so it worked perfectly.

Also as aaronyuri said above, the GPU produces tonnes of heat so exhausting it is the best route.
