Question How to use 3x360 radiators with MEG Prospect 700R (PC Case) ?

[Skybuck Flying]

I love the look of this PC case:

https://www.msi.com/PC-Case/MEG-PROSPECT-700R/Overview

I would love to be able to implement

1. AMD 7950 X3D 16 core CPU stacked with 3D V-Cache
2. NVIDIA RTX 4090

This particular PC case seems to be well suited for EK cooling solutions/radiators.

However there is a problem:

Theoretically this PC case can mount 3 x 360 radiators which would be needed to cool the CPU + the GPU both with water cooling.

However some of the EK cooling solutions require a DISTRIBUTION plate which would replace one of the 360 radiators, which would be a problem, because then there is not enough cooling to cool the CPU + the GPU.

The CPU is rumored to be able to generate close to 250 watts of heat.
The GPU is rumored to be able to generate close to 600 watts of heat (CHIP+RAM)

Basically the official narrative about both CPU and GPU are not thruthfull and could cause surprises for people building personal computers.

So for now I am going to assume that 850 watts of cooling power will be needed to cool these two hot components.

The general rule of thumb seems to be 120 mm/140 mm per 100 watts of heat.

So 850/100 = 8.5 so close to 9 fans needed. Hence the need for 9 fans, basically meaning 3 x 360 mm, which would be 3 x 3 x 120 mm fans at the very least.

Now I am wondering if there is a possibility to use all 3 radiator mounts, do away with the distribution plate, but where and/or how to mount a pump and a reservoir ?!?

What would you do if you had this PC case and wanted to mount this hardware above, is there a way to do it with 3 radiators of 360 mm ?!?

I am a complete noob with water cooling, so any help is appreciated.

Welcome to the forums, newcomer!

With 2x360's you're more than fine with the heatware you've mentioned in that thread's body. Unless you're thinking of cooling more than one system with those 360mm radiators. What sort of fans are you looking at to pair with that radiator? In fact what radiators are you looking at? Might want to go through the watercooling sticky linked in my sig space, should help you with your loop's parts purchase, setup and priming.

Hello, I try and answer your questions that my posting raised:

1. This PC case is designed to cool only one system as far as I know.
2. I am still in planning phase, so no fans selected yet. If it is true what you say it would probably be some kind of fans that come along with EK radiators/fans/distribution plate/matrix 7 and such. EK matrix 7/distribution plate seems noob friendly I was hoping to maybe use that, but now I am not so sure anymore, because some people with experience with water cooling systems are recommending 3 radiators. I am also not sure what kind of thickness is required or what kind of thickness EK cooling solutions/radiators are/provide or what will fit
3. No radiators selected yet, basically same answer as point 2.
4. Thanks for your water cooling sticky link, I will study it in coming days...

Some more information/specifications/schematics about this PC case, manual & document, pdf download link:

There may be some issues with this PC case:

1. I would like to be able to mount an E-ATX motherboard. This PC case seems to require a special side panel to do so, so does that mean the motherboard would hang over this special side panel ? Basically preventing the third radiator from being mounted ? (I could maybe go for an ATX motherboard, but have not decided yet).

The manual mentions:
(The side panel fans cannot be Installed simultaneously with
E-ATX motherboard. 側板風扇與E-ATX 主板無法同時安裝)

2. Not sure if all 3 radiators can be mounted a the same time...

However I have seen it on youtube, so I think it can be done... then again I have also seen builds with the distribution plate, so I will have to check again to see what I truely saw, I have looked at a lot of cases/videos, my mind might be playing tricks on me ! =D

This promotional video seems to suggest it is possible:

In another promotional video, the distribution plate is used instead:

Another promotional video, however this time it seems maybe only one radiator used, can't tell if the front is also equiped with a radiator:

The best most detailed video I have found so far is this one, however it doesn't do a full water cool build, but it does give a good look to the inside of the PC case:

In this last video the following motherboard is used and according to the specification it is (only) ATX:
