Alphacool NexXoS XP3 Light - Acetal Edition CPU Water Block
Fresh out of the box, this Acetal XP3 Light CPU block has a centralized inlet with the outlet at the top of the block with G1/4" threads. Along with the markings at the inlet and outlet, there is also a copper OCOOL nameplate, and it starts the black and copper theme found throughout the set.
Flipping the block over to have a look at the base, we find a thick copper plate held in with copper screws, and the mating surface has marks left from the leveling process but is fairly smooth.
The Cross-slotted structure has an increased pin count. Designed to work better than previous versions, the 0.5mm square by 2.5mm tall pins are what Alphacool found best to rid the CPU of heat and transfer it to the liquid in the loop.
Alphacool also uses an injection system to push the liquid into that pin array we just looked at. The slotted design allows for the best flow across the pins and also compensates for backflow with the channels running in opposite directions. Then, of course, after passing through the copper plate, the outer channel take the liquid to the port seen at the top right.
The hardware kit sent along with the XP3 Light offers everything you need to get going. There is thermal paste and a wrench at the top. There are four nuts to secure the mounting screws to the board, LGA2011 mounting screws, and four springs for all setups. At the bottom, there are four steel washers, nine nylon washers, four thumbscrews, and the standard screws for Intel and AMD mounting.
On the left is an AMD and potentially an Intel back plate since they send the LGA775 foam pad, but with no socket screw holes for Intel sockets, that plate is relegated to mainly AMD. To the right, we have the Intel and AMD brackets that set on the ledge of the Acetal top and secure the bock to the motherboard.
This is what is given for instructions for the CPU block. There is an insert stating not to use a wrench to tighten into the Acetal threads. The larger paper is a multilingual installation manual. The illustration shows an Intel motherboard, and as you can see, there is no back plate in that image.
