But who is the OEM/ODM of Liqmax III? I couldn't seem to find that after 20mins of searching. Enermax seems to have that under lock and key... but seeing as their previous Liqtech and Liqmax still had problems, it may be Apaltek again.
FYI:
NZXT Kraken M22
Msi MAG & MPG Coreliquid [The MEG is Asetek.]
Enermax Liqtech
Fractal Design Lumen [Haven't noticed a flood of complaints from this one - yet.]
^All Apaltek, and have had, or still having issues with clogs. Some prebuilts, like Cyberpower, are rebranding and offering them amongst their selection of coolers.
The clogging is going to happen eventually in these sealed coolers, but it shouldn't be as early as they have been popping up...
