So I may have been lucky all these years. I have installed a couple of dozens and I never had an AIO fail on me. I have used AIO from four companies (Antec, Corsair, NZXT & TT). The oldest one, Antec Khuler, still going strong since 2011. Maybe CM came up with a way to improve their own AIO, but I don't think it will be better than other manufacturers.
The Antec Kuhler was an Antec design manufactured by Asetec ... just about every CLC out there is made by Asetec (or some newer ones by CoolIt) ... so it's not a matter of it being better than "other manufacturers" but the same manufacturer.
They all have the same componentry which includes weak pumps and aluminum radiators.
1. Is the new CM unit still aluminum ? ... all I can say is

2. Can it deliver 1 gpm ? ....
I got no use for this unit
3. Does it still need 2k or more rpm to offset the above weaknesses ?
I got no use for this unit
4. Does it still create a galvanic corrosion cell my mixing a copper block with an aluminum radiator /
I got no use for this unit
While the pump redesign may offer some advantage, as far as we can tell at this point it may just as easily be a marketing ploy or a patent dodge.... time will tell. With the arrival of AIOs that are expandable, have copper radiators, < 2,000 rpm fans, 1 gpm + pumps ... there simply is no "raison d'être" for a CLc to exist.
