I'm interrested by this. No pump = no failure and no noise. This is why i got an air cooler right now.

[@googleaccountuser3116]

I just got a massive cooling block, no air or water needed. Just a soft air flow from the case fans and dust blocking fabric over the inlets. Much less power consumption this way. I already have a radiator in my room, no need for an additional dust capturing one. These fans only draw power and dust into our machines and now this genius is telling us we should ad some water to the mix. His pc is running at 40°C doing nothing while mine does 30°C at room temp. 40°C would be 100% cpu at my end.

Wieland: "All right then, keep your pump secrets" *pumpless straw sucking pumping (no)noises* I actually really like how plain it looks tbh, the prototype is giving me industrial design vibes and it's probably something that would look at home in a server chassis, I wouldn't mind also seeing the mounting screws be flush with the surface.

[@alexatkin]

Absolutely. I'm running a 14700k in my NAS/Server on a stock cooler (mad I know, but it was the number of cores I wanted rather than the boost speed and it was a straight swap from a 12400). It can fit a 240mm AIO, but I'm nervous about running an AIO 24/7. Something like this is more appealing as it should be more reliable than a pump.

They have been for a while once companies like arctic cooling, deepcool, and ek finally got around their patents.

[@marcogenovesi8570]

GOOD

[@retrofitter]

The block is aluminium probably to stop galvanic corrosion. The radiator appears to be a microchannel design used in automotive air-conditioning that can withstand high pressures of up to ~450PSI. The cooling tubes are not open but are bridged internally to hold pressure and to aid in exchanging heat from the fluid to the surface of the tubes.

[@Marcos-ee7nt]

If let's say they are using something that isn't water like 3m novec, would galvanic corrosion still be a problem?

[@Psyden5757]

​@@Marcos-ee7nt It depends on what's used, either case they could also maybe plate the copper block with aluminum to prevent that without a change in liquid formula i guess

[@techwolflupindo]

Only if the rad is aluminum. I learned the hard way with an AIO that had copper block and aluminum rad. Ended up using a custom setup with copper block and rad.

[@RicciChoi1109]

This product looks promising and I hope it would be launched successfully like the IceGiant

[@SpoiledBadgerMilk]

I wish ice giant would release a unit designed for am5 and Intel, respectively. For their consumer side cpu's. Currently ice giant's offerings are designed for amd and intel server cpu's. So they don't function right. When used on consumer cpu's. I really wanted one for my build. I was disappointed when I saw the reviews.

[@Akkbar21]

I was strongly planing on buying that product for my latest build, but the reviews scared me off that. Didn’t seem to have the extra cooling ability I was hoping for without the point of failure of a 360mm AIO.

[@ShrekLaBeouf]

I hope this will become the new standard. Not having a high pitch noise is obviously a big deal but in my opinion what really sells the idea is that it essentially combines the biggest benefits of both current AIO models (easy to fit in cases that have no space for a giant cube) and air coolers (no pump to fail on you).

[@pawcisq]

what do you mean nothing matters on the prototype! everything matters! IT IS GORGEOUS!

[@Lishtenbird]

This could definitely look great in an industrial mech build as is, yes! (I do agree that the market for this is way smaller than for a discreet sleek black one, but it's still cool in its own right.)

[@xapientiae]

Things that I would like to see for further testing with this AIO, if possible, would be how it performs: 1. with those radiator gaps filled 2. with pipes straight and as additional tests, that would be worth knowing for SFF: 1. with radiator mounted on the side (so maybe more convection in the radiator itself?) 2. on direct die (edit: whoops I forgot that it's aluminium) I know that this all would be very time-consuming, and thus these are only suggestions of (maybe) interesting tests, seeing any of them would be equally interesing.

[@bublikp]

"2. on direct die with liquid metal" - on aluminium block? That would be fun to watch))

[@quentinduch1625]

Regarding direct die with liquid metal, it's probably not a good idea as the coldplate seems to be aluminium, and aluminium is highly soluble in gallium.

[@IcecalGamer]

Liquid metal + Al cold plate 🤔

[@wille84fin]

Would be cool to see this with clear pipes to see what is actually going on. How the liquid moves around and so on. Interesting idea, maybe not practical for me personally at +250W load (12900K) but interesting and useful to someone else i'm sure.

[@SianaGearz]

You know what. Given the liquid metal suggestion is now dead, how about indium soldering it directly to the CPU core instead, if you want to test something in this vein?

Really appreciate this channel … unlike some of the larger tech KZbin channels that have clowns giving advice, Roman actually knows what he’s talking about. This AIO is a fantastic future option. One suggestion for improving the thermals of this system is to add some cooling fins on top of the cold plate and adding a small fan. Great concept.

[@uss-dh7909]

Was hoping someone would notice that too, big missed opportunity for some fins and maybe an optional downfiring fan like what artic has gone on with their AIOs.

Try sleeping with one of those in the same room as you while it's doing some type of work

[@SkinUpMonkey]

@@marcm. Did you know you can change the rpm of the pump which then makes less noise without hurting the performance much like 1c at worse. I got custom setup but run the pump at a lower rpm when the pc is not doing much then bring the speed up inline with the fans which is based off the water temp.

[@sebmendez8248]

Always great that you're always looking at new, interesting things instead of just the same old, same old, think that the companies benefit greatly from your testing and feedback. Have to say though of course having an extra 33% more water and radiator to flow through, of course it'll help and absorb some heat, of course it will be different from a 240 AIO. Would be curious to see it compared to a real 240 AIO.

[@Kirainne]

Great video. Really informative and I'm looking forward to the potential future of pumpless long-service life AIOs!

[@JJFX-]

I would have liked to see you test it in a pull configuration to reduce the impact of that bottom gap and in different orientations. My main concerns are how difficult it would be to refill and if it can still perform mounted on its side. Not having a pump is great but every AIO I've owned permeated fluid long before I was ever concerned about the pump failing. Pump noise has been a negligible concern for me but I'm aware some AIOs are surprisingly loud. Very impressive prototype overall. With a copper coldplate, improved fan mounting and no paint on those fins, this could get interesting if the price is reasonable. A thicker radiator would also help to make this standout.

[@JohnWilliams-gy5yc]

I wonder if the coolant is non-conducting too. That would be a big plus for me and could make me consider this one over an air cooler.

[@pbe6965]

If it's a solvent, it might damage the hardware in other ways in case of a leak. Automotive coolant is non conductive by the way, I had quite a lot of it leaking in my build and my machine still ran fine until I saw the spill on the floor (and tbh the smell became noticeable too). I never tried the cheap stuff, but any branded coolant is supposed to be "anti corrosion" and I believe they achieve it by being non conductive as to limit galvanic corrosion in an engine cooling loop where different metals mix. I cleaned it, replaced the cpu WB that was leaking, and it's like it never happened.

I love the industrial look and the red on white color is unique.

[@mini-pouce]

Good news to see this type of cooler for consumer PC, and quite amazed by performance, it is holding a 7950X. It's probably a single phase thermosiphon, easier to engineer and less sensible to placement (you could do front monting too). For the tube going donward it is not a problem since it is driven by density difference at hot point versus cold point, if it is enougth to moove against gravity then it is allright (just dont give it too much head loss ofc, same for pumps). Phase change seems more promising for permormance, thus it depend on the fluid I gess, but also less quiet so if it work as single phase that's fine for me.

[@vailpcs4040]

My guess is that this is a dual phase design based on the single pass radiator. With a single phase, I'm pretty sure you could use a dual pass radiator, but a thermal scan of the radiator in use would likely confirm.

[@herrakaarme]

I have used AIO coolers for over a decade, and I most certainly would be interested in a pumpless one like this. If it's Made in Germany, I reckon it wouldn't be the cheapest option, but if there's no need to worry about a pump dying and especially pump noise, it could be worth a little bit of extra price.

[@OTechnology]

I'm curious if it would perform better with the block flipped since the bottom tube is hotter.

[@Zenefor]

i think this silence aio uses valves or flaps that create pressure from warm water that close and open when heat cycling, force pushing each other against a loop. (My speculation, but I also think that the silenced aio might creaate a void of air on cold water side that might push it downward for cycling)

[@OfficialMageHD]

For a moment I thought this was going to be a new version of that phase change AIO you made before

[@dwahnaslowdown8887]

It seems odd that the right side hose (from the lower port) is the warmer one. I would expect the coldplate to be oriented such that the upper hose is the hot exit and lower is the cool inlet. Flow would be assisted by gravity and the slight density differences between hot/cold liquid.

[@mannyc19]

[@Damianhardman]

Really exciting product development for people wanting quiet PCs. @derbauer EN: 2 suggestions. 1) Put the fans on the other side of the radiator, it looked like there was a much smaller gap between where the fans would mount (although that maybe down to the video angles). 2) No clue how the cold plate is setup, but I would of expected the hot coolant to of exited out of the higher tube (out of the cold plate) not the bottom. I wonder if putting the cold plate the other way round (so Wieland is upside down), would provide slightly better results.

[@D.u.d.e.r]

Very cool product, thx 4 highlighting it!

[@stancartmankenny]

A way to fix the gap problem mentioned at 8:30 would be to make it a pull configuration, e.g., put the fans above the radiator instead of below. That should be an easy quick test to see if it makes a difference.

[@fusrodahize]

[@twinjuke]

Hey, great review again. Question: doesn't it help if you place the radiator at the front panel vertically to give the temperature difference a help?

[@silkysoftaus]

It has standard mounting holes on the otherside right? Just mount the fans on the other side, gap looks way smaller.

[@prodeous]

This is cool. Guessing it has to be in certain orientation. As in radiator at top. You mentioned air flowing from the sides, anyway to add paper baffles in the gaps to reroute and retest?

[@NEKRWSPHERE]

Skips 9 minutes ahead, watches.... No thanks... I'll stick to my pump.

[@AlphaMachina]

I'd like to see if this can close that cooling gap by taping off those open sides on the radiator.

[@robertlawrence9000]

Very interesting! Thanks for showing us!

[@Qyngali]

I wonder if flipping the cold plate vertically would change anything. Looks like it would avoid the low point of the tube on the left side? Also, blocking off the gaps between the fans and the radiator would be interesting.

[@SinsiCHD]

Can you mount the cold plate top side down? The way you mounted it, hotter pipe was coming from the bottom of cold plate, if you mount it upside down, hot pipe will be at top of cold plate and may serve to get a better circulation if there are one way valves inside?

[@spankeyfish]

I wonder if it would perform better if you shortened the top hose so that it only slopes upwards towards the rad. Thermosiphons are gravity powered so they're sensitive to the position of everything in the loop.

[@radn0x]

Very cool product, thanks for sharing !

[@Speak_Out_and_Remove_All_Doubt]

Love this product! I even really like the red and white colour scheme. I wonder if you can 'beef it up' to make it better? Obviously the fans can be improved like you said but I wonder if you made it twice as big would that improve things significantly or is that not how these kind of thermal siphon work?

[@DrMuFFinMan]

Would love to see more of something like this come to market. Less points of failure and with more tweaking like distance between fan and radiator and you'd have a pretty good cooler. Do wonder what the trade off or limit would be for something like this in the future.

[@ronny332]

Interesting product, very well presented, as usual. Thank you! 🙂

[@Macazian]

For the "No Maintenance" clause. Does the internal liquid ever need to be drained, radiator cleaned out and refilled. After a few years with any type of gunk build-up?

[@ABFox]

Cost and lack of maintenance sound debatable. Is there any extra manufacturing costs associated with the fluid used and pressure (or lack thereof)? If it relies on the pressure and a fluid other than water, will it break down or lose effectiveness over time? I'd like to see at least the longevity question answered before I'm ready to decide.

[@Barrett_Fodder]

Great review as always. Could you use some strip of foam or rubber to cap off the airflow lost on the ends then remount the fans? If you could do that for an additional test and then raise the output side line to see if it affects the temperatures on back to back runs that could be insightful. I'm also curious what an automatic fan curve or much higher fan speed would do. Would it actually lower temps or have you already reached the thermal conductivity of the aluminum plate and fluid. Curious minds want to know! Cheers,

[@L0wPull]

[@kelownatechkid]

[@PoRRasturvaT]

Could you run a quick test by filling/blocking those holes on the side? Just a matter of verifying the block potential instead of that overlooked part of the radiator design.

[@infango]

I wonder how would it work with 3M Novec 649 as cooling component ? ( maybe Ethanol or Acetone )

[@Phos9]

If it’s using convection to move the fluid I can’t help but wonder if larger tubes would allow more flow, or if it makes very little difference and all that matters is the temperature differential

[@SaperPl1]

Can you perhaps do a 3d printed funnel to increase pressure where the gap between fan and radiator is? Or use those noctua pieces and just stuck them inbetween? Also could you try to put left pipe/hose the way it doesn't sag? or put the whole thing higher so those don't sag?

[@glebglub]

I was thinking putting the fan on the top, at least for an experiment- seems the gap is smaller there but that could be a trick of the camera. an entire funnel might not be necessary though, just a shroud (or even a thick wad of plastecine, but since it's a prototype no doubt they want it back and this could prove problematic). maybe even just duct tape would work lol. weird that it's painted white though - it may be a minal impact w.r.t. black body radiation causing a feedback-loop in a closed case (especially since it can't be mounted externally), but the layer of paint will mitigate some efficiency from the fins. but again, they probably want the prototype back, so removing it manually isn't an option here

[@piast99]

If that is a thermo-syphon then shouldn't the radiator be placed vertically so the cold liquid goes down? The pressure difference and flow rate would be much bigger, wouldn't it?

[@KelleyStrzelczyk]

Maybe those brass fitting are for more choice. If you want both one either end. I wonder if you can hook up the gpu to those other fittings.

[@Powertampa]

I had a Swiftech AiO a while back, yeah I know, but it eventually had a pump failure as they tend to do. Thing is, I didn't notice until I really pushed it with rendering. Playing games and doing other productivity things it was still fine. Granted the pump could still have moved a bit of water around, but opening it up the shaft was well and truly broken off eventually. So it doesn't surprise me that a passive solution for water cooling would actually work if carefully designed. Certainly for most people that don't run games that use all of the cpu this would be a good option. With some refinement it could very well be a viable product for the middle of the road systems with overall lower TDPs, like your i5's and stuff. Good to see some actual movement on this stuff as well, feels like hardware innovation kind of stagnated the last couple years.

The orientation of the radiator could be important as well, vertical with the “hot” which is the top connector on the cooling block line to the top inlet on the radiator.

[@ItIsNot1984]

could it help to add some fins to the block to make it function passively as a heat sink? I'd love to see this come to market. The AIO has become a necessity, but I really hate them because they always end up noisy after a year or two.

[@abb0tt]

You can see a subtle horizontal color gradient on the AIO in the FLIR footage. I’d say there is a lot of potential in refinements and optimization.

[@williamdouglas8040]

The biggest issue with this design is that the vacuum will eventually leak due to those plastic tubes. With a metal liner it might take years, but they will leak. But I guess this is not so bad as long as one can reestablish a vacuum. Possible methods of improvement: - copper cold-plate. Al is probably used to match the radiator / prevent corrosion. - higher vacuum so the liquid boils at a lower temperature. - parallel hoses for the water vapour to transition to the radiator (only 1 return path should be sufficient). Dropping the boiling point will result in more vapour going to the radiator. - add a pressure gauge so we can see what sort of vacuum is present. Perhaps a USB connection to allow for automatic monitoring of the vacuum and alerts if required. So a cool idea, but really no different then the heat pipes that are in every air cooler. They are definitely effective, but I'm afraid reliability will be a problem. Gasses can flow through plastic - albeit slowly.

Super interesting, can be the future of "AIO" ! You can easily improve & retest it by putting the fans on the top of the rad rather than below as (badly) designed, and test outside of a case (or in pull mode)

I love the look of the prototype and fans a lot. Very industrial. Could you contact the company to get more details about the inner workings etc?
