In a closed AIO cooler the heat travels from the processor to a radiator that blows it out of the case — and the size of that radiator is the first constraint. The 240 mm units fit most cases, while 360 and 420 mm ones require a roomier chassis and enough fan mounts. The range includes MSI Coreliquid, NZXT Kraken and Darkflash models as well as be quiet! Pure Loop 3 coolers; also make sure the package contains the mounting hardware for your own processor socket.
