Topic 227650

Hi,

I have a Cool Master ML 360 Mirror (AIO).  The rig is currently sitting on a table.  I have just elevated the radiator a couple of inches from the table surface.  The radiator is laying on its side.  It is not stable sitting on its end.  The MB is (almost) on the table surface.

  1. Should the radiator fans be "sucking" through the radiator.  Or "pushing" (blowing) through the radiator?
  2. Should each radiator fan be plugged in separately? Or through the consolidation harness?
    1. I have two CPU fan plugs on the MB.  And three fans.
    2. The fan consolidation harness has a "Red" plug.  Which CPU fan should be plugged into it?
  3. My MB has both an AIO connector and an AIO+ connector. The "+" connector appears to have a higher amperage listed in the MB  Manual.  The AIO water pump specs seem to be perfectly happy with the AIO jack.  I currently have it plugged into the AIO+ jack.

The reason I am asking these questions is I want to maximize the cooling effect.

I am beginning to wonder if I would get better cooling if I move the whole system into a tower case with the radiator at the top of the case?

Hi Tom,You won't get any

Hi Tom,

You won't get any "better" cooling performance than what you're getting now.  MAYBE if you put the cooler in the roof of your case, but I doubt it.  The best cooling comes from outside the case.

As for your questions, I'll answer them as you asked them.

1. It does not matter which way you have the fans, either push or pull.  You will get slightly better cooling with a combination of push & pull fans, but not much.  Plus, I don't know what case you are going to be putting it into so I don't know if your case can handle the push/pull arrangement within the case.

2a. Again, either way works just the same.  If you notice the fan specs, the amperage is quite low, and all three fans will be less than (added together) 1 Amp.  To my knowledge, I am not aware of any motherboard having less than 1 Amp for a fan header. 

2b. The fan consolidation harness with the Red plug is far the computer's motherboard to be able to count the fan's rotation speed, or RPM.  You will need to have at least one fan plugged into it so that your computer knows that you have a fan cooling the CPU, or you'll get an error code for no CPU fan detected.

3. The one header with a "+" will be for your water pump, I would use that one.  The fact that your AIO water pump is "happy" being plugged into the AIO header is okay, but it may be close to the limit of that header's amperage rating.  As I said, I would put your AIO into the AIO+ header, or jack as you call it.

.....[EDIT].....

If you want to get more cooling, you'll need to spend more money and get the Noctua industrial fans, the ones that spin at 3,000 RPM and replace the ones that came with your AIO.  Faster fan speeds = better cooling, but at a cost of higher noise.  It is up to you whether you want to spend the money on noisier fans for better cooling.

Very good analysis and

Very good analysis and synopsis, George.

The Noctua IPC-3000 fans WILL make a difference, though maybe not as much as you expect.

You are still limited by the flowrate of the pump and the radiator size.

The 3000 iPPC fans are also

The 3000 iPPC fans are also quite loud (at full speed), if that’s any consideration for you. 
 

the 2000s are a lot more reasonable IMO.

So bottom lines are  You

So bottom lines are 

  1. You can get from here to there but
  2. It would get noisy
  3. Get more expensive
  4. Don't do anything (status quo).

So the other choice is stop pushing it so hard. Seems like CPU boost and no CPU multiplier runs cooler :(

Maybe that is best choice for the summer.

I think I raised this issue

I think I raised this issue in another thread but haven't been able to figure out where the responses that Keith, Ian&SteveC posted those really good replies on.  Internet Researchers Question?

I am looking at upgrading my Epyc 7742 (Quality Assurance Sample) from a currently barely enough low end Air-Cool to either a high end Air Cooled solution or an AIO Liquid cooled solution.

My budget Knee jerk is currently not letting me explore those assemble it yourself custom liquid cooled cpu coolers.  Neither are my fumble fingers.

Is this still state of the art Air-Cooled?

It will be waiting till the first seasonal job paycheck hits.

Yes , still the best

Yes , still the best performance air cooler for Threadripper/Epyc.

There are TR/Epyc water cooled solutions also other than custom water cooling.

There are several 360mm AIO's that work for TR/Epyc also.

An AIO is all self-contained.  Does not need assembling like with custom cooling.  As simple as bolting it onto the cpu and mounting the radiator in the case.  No more difficult than air-cooling.

Silverstone IceGEM 360 AIO (full coverage IHS coldplate advantage over the Corsair, quieter also with equal cooling)

Corsair H150i Capellix 360 AIO

I can vouch for this choice as I have just installed it on my son's Ryzen 5950X system. We only had to change the CPU mounting bracket from an Intel one to an AMD type. The liquid loop comes assembled and self contained. The Corsair case we had allowed mounting of the radiator/fans on either the front or underside top of the case, we chose underside top position. There is a controller module to plug everything into - for power and the pretty RGB lighting thereof. We are quite pleased at the how quiet it is under load. Our only complaint is minor : the small font & diagrams of the supplied instruction booklet, but you can find it as an online PDF. The price is not cheap - AUD $279 - but at least you get what you pay for.

Cheers, Mike.

I have made this letter longer than usual because I lack the time to make it shorter ...

Oh, no. There are only 15

Oh, no. There are only 15 Silverstone's left in stock. I must hurry to order.....
