Unusual Dell oem liquid cooler for XPS630i

HSG, SYSM, Cmade by LG, LIQD, DRUID

D773N

uses a retention ring P113M (CARR, RETN, LIQD)

for liquid pump

i have never handled one before,

question how the shroud is fastened to motherboard and where does liquid pump power connector plug in.

the most common 630i cooler is small tower style air cooler N764D for LGA775 socket, which incidentally may be c/w LGA1366 too if the screw retainer set is removed, rotated, reinserted.
