Now coming to the AIO's performance, by the benchmarking done by Der8auer, he noticed relatively decent gaming and synthetic performance of the Wieland AIO, when compared to Corsair's H150i, which comes with a great onboard AIO pump. The average temperature difference between both AIOs was noted to be 8 degrees, which isn't a lot compared to the grand scheme of things.

Imagine having an AIO liquid cooler without any onboard pump, potentially getting your noise levels down to zero, well a solution has arrived.

Other than the pressurized radiator, this seems like it has the potential to be very affordable.
(HFC-245a [assumed] is more expensive than some other refrigerants, but still minor in BOM)
-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.

Thanks to BoggledBeagle @TPU, we have some more information.
Wieland already makes and sells Thermosiphons:

WWW.MICROCOOLING.COM

Thermosyphons - MicroCool brings decades of experience both engineering and manufacturing enhanced boiling surfaces. Brazed Construction.

The 'new' cooler in question, looks like a direct development off of those.

It appears that both the Industrial and Consumer 'attractiveness' comes from how quiet and reliable it can be.

100W Processor, to 70c. (20c ambient, 10cfm)

-is not all that impressive (if comparing to a high-performance AIO/custom loop).
However, there's lots of non-OCers that buy AIOs for their low-noise.

 

These Wieland thermosiphons would be even quieter, while allowing heat to immediately be put outside a chassis/enclosure.
(with reliability approaching a heatpipe aircooler)

 

 

HFC-245fa Refrigerant/Propellant is commonly used in closed-cell spray foam insulation. -and, is a replacement for Ozone-depleting Refrigerants/Propellants, previously used.
It's apparently 'safe enough' to be in existing consumer-available products and medical use.


Leaks (mishandling, age, abuse) from the Wieland Thermosyphon should not maim/kill from a single exposure, or extended extremely low-level exposure.
(The main health-safety concern with HFC-245fa is simple asphyxiation; very unlikely to occur w/ such a small volume involved.)
