Hey @Hilbert Hagedoorn on page 4 you say "The provided 140 mm fans run at a maximum of 1700 rpm and feature a maximum airflow of 72.8 CFM. That’s the theory, but in reality, the range of useful RPMs is even wider:" The fans run at 1700rpm, but the revision of the press samples received was reporting either the pump rate or the rpm's of the fan on the block. Retail models don't do this, and report the fan rpm instead.

Be aware: Artic are misinforming customers that this cooler is not compatible with Socket R(2011) (Square ILM)

Socket 2011 and 2011-3 are not compatible to each other, so the Liquid Freezer II wont work in general on your Bord. Stay safe and healthy.

The Liquid freezer 2 uses the same 2011 spacers as the original liquid freezer, Both the 2011 and 2011-3 are 80mm square ilm with the socket positioned the same. While the spec sheet and product page says 2011-3, The Manual lists 2011(-3), the FAQ notes that this designation is compatible with both 2011 and 2011-3 [spoiler]



[/spoiler] One might assume that Artic simply hasn't tested it, but the correct response in that case would be that support cannot be guaranteed as it hasn't been tested, not a blanket (incorrect) statement that the socket is not compatible. LGA 1366 is compatible with the 115x standoffs so long as a thread compatible threaded backplate is already installed.

sykozis:

Installing an AIO in the front of the case with tubes down is ideal, but not always possible.

That can end up being as bad as mounting it at the bottom and not recommended by the AIO manufacturer (reference: Arctic's manual for the Liquid Freezer series), quite a few cabinets are also build so you can't mount it with the hoses towards the bottom. Thing is, in some cabinets you can end up having the pump/block higher than the radiator. Golden rule is to have the cooling block lower than the highest spot of the loop. Ideal is top mounting it to avoid bubbling noise in the radiator, which you can get when front/side mounting.
