The Zalman LQ315 is also of Asetek design, just different generations.
Like the others, removal of 12 screws and the unit splits apart into two halves. Upper half on left, lower on right.
Another 8 will separate the cold plate from the lower half. There is a gasket that directs the fluid to the center of the cold plate, out the left/right and pulled back into the loop via the impeller.
On the underneath side of the gasket is a channel, this funnels the coolant down through slot in a sheet metal shield.
Pulling the upper half apart the back of the top has cleat plastic with painted lines to help defuse the LED light on the circuit board.
