AIO vs custom water cooling ?

[Dimitar Maslarski]

Hello I've got the cooler master CM700 case which can support 2x420mm radiators so I wonder if i should go for custom build and water cool everything or just an AIO cpu cooler for the ryzen 5800x because my rtx3070 suprim x is already with pretty decent air cooler .
Would there be difference in thermals for the cpu AIO over custom loop ?
Also I'm looking at all the AIO coolers and don't mind spending the extra pound for one of then ASUS ROG AIO cooler but would they perform at the same level as something more popular like the Arctic Freezer II ?

A good AIO with a large radiator will do a perfectly adequate job controlling a 5800X. But so will a really good HSF like a NH-D15. Your 3070 is probably ticking along nicely in the 60s maybe?

Custom watercooling will cool more than anything else but mostly it's about aesthetics. Unless you're overclocking and trying to get every C you can, you don't need more than an AIO.

But it looks much better

So I went with the aquacool eisbaer 420 AIO now the question is should I mount it in the front or on the top of the case ? What fan setup should I also use with the case for good airflow ? Does the radiator mount straight onto the case or I can put case fans and the the radiator with its own fans ?
And yeah the rtx 3070 suprim tops at 65*C In my old case which doesn't have great airflow and stays below 60*C with side panel open. Haven't tried it in the new case but I would try to make it just as good as with open side panel or as close to that as I can get.
Also any suggestions for case fans ? I'll need to buy 9x140mm I think and I want something that looks nice and performs great if there is such a unicorn out there lol. Preferably with Rob.

If the case you are going to use can definitely take a 420mm in the roof, put it there. Two reasons:

1. hot air is all exhausted from the roof, cool internals, and effective.
2. the radiator will be above the cpu block/pump meaning bubbles stay in the radiator.

The radiator should mount straight to the case. The roof panels can hold that radiator without modifications.

You can use the fans the Eisbaer comes with but that means you may have varying fans through your case. The CM700 will come with some I expect.

Now, if aesthetics are important and you want all the fans to be matching, it gets interesting. Three on the front, three on the rad in the roof., one in the rear. So I make it 8 140mm fans.

Do you want RGB? ARGB? DRGB? Airflow? Static pressure? Silent?

If you want named brands like Corsair or Lian Li, 9 140mm RGB fans will cost a fortune. I mean like >£200 for fans plus two controllers (each controller can only do 6 fans).

Noctua (ugly, no lights, very high quality) again that's nearly £200.

Personally I recently bought a set of GIM KB-140 which was three 140mm fans with a controller box and a remote (only 30cfm, but also only 15dba) for £26 delivered chinese but they move air quietly and have pretty lights, what's more to ask?

Budget is not an issue i'm willing to spend on that PC cuz i'm not gonna upgrade anything on it for the next 5 years apart from GPU probably so don't mind spending the extra quid now.
As for fans i'm not fussed if they're different as long as all have some lighting on them i think i'll run a white or red RGB all the time.
Not sure what the different RGB are or what's the difference between them as long as they glow i'm cool .
As for the case it also can mount 2x140 fans on the bottom should i do that and make them intake so they can cool the GPU?

I've read reviews about the arctic freezer ii and the little fan is supposed to be pretty quiet .

So i've still not decided on what fans to buy. I read pretty bad reviews about the Corsair ML140 Pro Magnetic Levitation fans.
I like the look of Cooler Master Masterfan MF140 :

These are 120s but i can get the same 140mm but i don't think they are the best for the radiator. Maybe i'll it'll be best to buy different make Radiator High Static Pressure fans ?

Tried few times, for some time, the Arctic Freezer II and never managed to hear the little fan. And yes, it does help with temperatures.
To be honest, I wouldn't bother with a custom loop if wasn't for the GPU.
I believe my 3900x runs cooler than the 5800x, not sure, but the Arctic Freezer II and the Dark Rock Pro 4 were more than sufficient and virtually silent for my CPU.
I was back to AIO, but just before Xmas got the 3090, and the noise + temperature + case turned into an oven, decided to go back to a custom loop.
I understand that the GPU has warranty, but as I intend to keep the card for some time, didn't want to risk the card dying days after the warranty.
installing a waterblock voided my warranty, true, but is less likely to die now at 45C under load, and memory junction at 50's, than before at mid 70's, memory junction at mid 90's and NVME and RAM bathing in hot air.
If your GPU runs quiet and cool, a decent AIO should do.
A good case with bottom unobstructed intake should help the GPU a lot.

For the Arctic Freezer, all fans are connected in daisy chain. The first one connected to the pump.
You only have to disconnect the first, use a common 4 pin fan extension and control the fans as you wish, but to be fair, mine was 50% when CPU up tp 60C, 60% when CPU up to 70C and a blast 100% when CPU over 75C.
Unless stress testing the CPU, never managed to hit over 70C. Maybe because I use an offset -0.1, and the 5000 series people use curves, but it was very quiet.

I'll probably mount the GPU vertically right in front of the front intake fans as I have a bracket and riser cable. That way its gonna get cool air easy. In that case I wonder If I should bother with bottom case fans.
Also what do you guys thing of these fans :?
