You can find info about this case here:
https://www.arctic.de/lf-service...According to Arctic, this only affected units shipped between Mai '21 and March '22.
Further below they inform, that if your device has a "QC Pass" sticker, that everything is OK.
I ordered the Arctic Liquid Freezer II 360 A-RGB on October 24th this year and my unit has this sticker. So I assume that Digitec has the latest/non trouble making version. At least for this model.
I'm also very happy with the looks, performance and price of it!
