Pumpless AIO that actually works, tested by Der8auer

[dgianstefani]

Fixes one of the main issues I have with AIOs - weak pumps that wear out and are noisy.

Cools 200 W no problem, 36000 points instead of 36300 with a corsair 240 AIO, prototype, still room for improvement.

Custom loop will still be much better, but this fixes the reliability and noise issues with AIOs, while eliminating cost from manufacturing.

I watched this earlier and found it very interesting

 

[jesdals]

Now a 360 solution with Der8auers recommendations applied and I am all in

 

[Waldorf]

nice.
but i still prefer something like the eisbaer, and replace the pump (either right away or once it fails)
with a D5 clone/res, which cost me 35$ on A., and i still dont have to do a custom loop (if its not my rig).
and so far, its inaudible, even with fans throttled (low load), with my case (and pump) 2ft away on my desk.

 

[oiawshboiwsahnoidaws]

wonder what liquid they are using and how volatile it is

Hi,
Yeah 240's have never really been very good at much anyway
280's are a bit better minimum but 360... are pretty much the minimum you'd want to mess with.

Expandability might be a more interesting aspect since it has four ports hehe

My Thermalright 240mm keeps my 5950X pretty cool. Could be the 3300 RPM pump speed though. AIOs are still fine to use. For most AIOs the source of noise is not the pump but the fans. The fans on my Cooler Master Nepton 280 were just as loud as a hair dryer. That led me to Phanteks fans.

Hi,
Yeah I'd never do another 240mm anything personally but yeah fan wise they do have a lot more rpm than 140mm do hehe

@ThrashZone
except not all cases allow a 360 where a 280 fits,
and i prefer a copper 280, over any alu 360.
and so far, temps arent an issue with any ryzen i had, even with throttled ~10$ (arctic) fans..

loved my resorator setup ~10y ago, with the pump replaced,
having almost 2gal of coolant was awesome.
30 mins of low load, before water temps even changed..

 

[dgianstefani]

Guys, the 240 mm is just a prototype, there's literally no reason why this technology couldn't be integrated with every popular radiator size.

 

[Waldorf]

not much difference between "mounting" this on a 240, vs 280/360?!

surprised its based on a corsair (aio), as i dont remember them coming with G1/4 connection
like the Alphacool or EK AIO, would be much easier to convert those.

When I got my Eisbear it sent me down the Watercooling well. Alphacool really do make some really good products, it is too bad they are expensive (not as expensive as EK) where I live.

 

[Waldorf]

yeah, even in CONUS, i found them on A, but extremely overpriced,
as non-amazon sellers (outside the US) charged extra for shipping..

so far, maybe not as cheap as the Arctic units, but if you wait for a sale,
i always founds them online within 10-20$ of others with sealed/proprietary stuff.

After my Nepton I got the Eisbear 420MM. The Rad currently cools my 7900XT. I still have the pump/res and may use it in a HTPC build I am putting together.

Cools 200 W no problem...

This is interesting, I wonder what fluid at what pressure are they using.

AM5 CPUs are really not good for this kind of testing, because due to the thick heatspreader they cannot put out too much heat before they start hitting temp limit. So the cooler may be able to cool more than 180W.

Hmm, I should amend my first post

The mixed metals and general cheap quality with a limited intended service life still remain inherent to AIOs.

 

[Space Lynx]

we were all wrong.

Weiland Industries is going to own everything. We all thought it was Weyland.

Big things have small beginnings ~

so my takeaways agree with his:

make it 360mm, make fan pressure much better, which should be easy to do from the looks of it, and make the cold plate copper.

once all of that is done it might match AIO's.

 

[BoggledBeagle]

I wonder what fluid at what pressure are they using.

In their thermosyphons they use pentafruoropropane, which has a boiling temperature 15°C. If they use the same stuff in that cooler, they would need to pressurise it to increase the temperature.

do you know why the European Union banned the original no pump fluid he talks about? what was the EU reasoning?

 

[ShiBDiB]

this fixes the reliability

It replaces the reliability issues with the pumps with reliability concerns with pressurized fluids/gases.

This feels like re-inventing the wheel.

Their server grade cooling that uses the same concept has extremely high reliability.

It's not a high pressure system, just enough gradient to cause fluid flow. Well within tolerances of the plumbing used.

Pressurised fluids/gases are a very simple problem that we've dealt with for a long time. Undersized and underpowered cheapo pumps however, they're basically a consumable.

 

[LabRat 891]

Other than the pressurized radiator, this seems like it has the potential to be very affordable.
-From what I can see, everything on this demo unit (except the cold plate) was off-the-shelf.

Kinda surprised I haven't seen more of these kinds of coolers. This cooler seems like something an HVAC tech would throw together in their spare time.

No. Pentafruoropropane looks safe though.

air coolers with a just slightly stronger fan curve can come within 2-3 Celsius of any 360mm AIO based on what I have seen, I think personally I will stick with the Frost Commander 140, but this is very cool none the less.

for some strange reason even a heavy fan curve on my Frost commander 140 and the fans are still barely audible. meh

I'm also an air guy, water or whatever this is considered just adds another failure point for minimal gain for 99% of use cases.
