Question about single radiator aios

[Magister]

Hello everyone,

 

I have an IBuyPower Revolt 2 Case that I absolutely love! But cooling in there sucks and very limited.

 

I am liquid cooling the gpu with a kraken g12 and liquid cooling the cpu.

 

Here’s what fits in that case:

 

2 120mm aios

1 140mm aio and a 120mm aio

2 140mm aios (but not secured)

 

What would be the best config for this?

 

Second: would a 120mm aio with two 120mm by 15mm fans in push/pull be more efficient than a single 140mm with a single 3000rpm fan (or possibly two 140mm by 15mm fans in push/pull?)

 

Thanks everyone.

Welcome to the forum!

 

I wouldn't water cool the GPU. Use the extra space for a 240mm radiator.

 

unless you can't do that with your case...

 

Also, what are your specs (Just to see how much heat they produce)

I had a 280mm aio with a 9900k with a z390 mobo but that was overkill. Downgraded to an 8700k now I switched to Ryzen

 

My GPU (AsRock Phantom Gaming D 5700XT) would get to 90 degrees underload with a generous undervolt.

 

My current specs are:

Gigabyte AORUS B550i

Ryzen 3600XT (overclocked to 4.5ghz)

NZXT Kraken X42 (140mm aio) with stock cooler (cpu)

XFX Radeon 5700XT with an NZXT Kraken G12 with Asus Ryuo (120mm aio with that 120mm by 15mm push pull)

 

This liquid cooled 5700XT hits 80 degrees under load and I get better performance than my phantom gaming gpu. (overclocked to 2000mhz with vram at 1800)

 

And although I do not kind the noise, this current liquid cooled setup is much quieter of course.

 

I purchased a Thermaltake Water 3.0 140mm aio and a noctua fan (because having an RGB Cooler in a case where you can’t see it is useless but I wanted a proof of concept.)

 

I’ve included pictures of it’s current state.

 

CPU gets 70 degrees underload with this setup and I’m sure it’ll be better with the new 3000rpm fan.

 

I just want to get the best performance possible in the case with some overclocking but not throttling on any component.

The case is design for hybrid gpus. 

But your config should be ok.

 

Your biggest problems are your pumps are at the top of the loop. This causes air to sit in the pump and the cold plate. 

This will result in poor performance and loud pump noise. 

 

Second a hybrid gpu cooler will exhaust heat off the gpu out of the system. The fan that mounts to the g12 will not. 

 

Recommendations 

 

Check the aio pump for additional noise. This will be a clear sign of air in the pump. 

 

Maybe reversing the airflow in the system will help. You need to raise the feet off the table a little higher.

This will make for a negative pressure airflow design. The downside to this will be more dust and need more cleaning on a regular basis.

 

 

It is an interesting system being hands on would be nice. But a lot more pictures of many angles would help.

[Magister]

Thanks! I do understand the issue with the pumps being at the top of the loop. When I first installed everything, I had some noise but I just tilted the case around to get water flowing and I have had really quiet operation since.

 

Again, not ideal but works. 

 

But reversing the airflow, do you mean flipping the fans to intake rather than exhaust? I also have two noctua 80mm fans that I can mount inside of the case. I have an adapter to stack them and they sit above the 120mm fan on a metal brace and behind the gpu. (This also blows across the gpu a bit.)

sorry i didn't realize that you were already running the rad as exhaust. 

 

After thinking about this for a while and some research this is what i got.

 

• first lets cover the what the default config is:
  •  intake from the bottom
    • 1x 120mm aio intake
  •  exhaust through psu
  •  exhaust through gpu blower style gpu cooler. (hybrid or standard blower it doesn't matter)
    • if hybrid  additional 1x 120mm aio rad at bottom intake with blower as exhaust
• your config:
  •  psu exhaust
  •  cpu rad exhaust (bottom)
  •  open air gpu cooler modded to use aio- rad at bottom set as exhaust- vram fan blowing from top to bottom
  •  also noticed that you have an air filter on the exhaust. this should be removed if you chhose to continue with exhaust at the bottom. it only hurts the airflow and does nothing for dust control.

this make for a rather extreme negative pressure build and the system is fighting for air and the hottest part of the system is going to suffer. in this instance the gpu.

 

before i continue i still want to stress that the pump maybe still be hindering some performance

 

• here are a couple recommendations to test:
• r1
  • bottom aio(both) intake
    • i would ditch the dust filter and just deal with cleaning on a more regular basis. (if you have an air compressor it makes it really easy)
  • psu exhaust
  • gpu vram fan set to pull instead of push
  • if you have room to add one of the 80mm fan to help exhaust somewhere it would be a recommended.
• r2
  • gpu ram intake
  • cpu rad exhaust
  • psu exhaust
  • gpu vram fan pull

this may make for a mixed of hot air circulating back  in the system, but if you can get more balanced temps between everything i would call that a win.

 

with all that aside if r1 and r2 don't work out you can drop some dollars and do a custom loop or use an aio that is expandable

I was actually just looking at EK options. A pump/res combo could be attached to the front plate where a 3.5” hdd would fit. I could use a 280mm radiator on the bottom, purchase the water block for the 5700xt (or get the liquid devil) and a velocity copper block for the cpu.

 

I wish Gigabyte had an AORUS water block for the 5700xt but they do not.

 

The config would also cost me $680 so I’ll have to wait a bit haha
