Component Technical Properties

The water block, as you can see from the photos above, consists of 2 parts: the cover is in Acetal with at the center the golden label of the company logo, while the block, which is in contact with the VGA is a single copper block. Made with milling machines with numerical control, the copper is now the best material for the thermal conductivity so, the best choice to do so. The Alphacool has further improved the performance of NexXxos NVXP GTX580/70 increasing the thickness of the contact parts of the video card with the components of well 5mm. The total weight is in fact about 1000 grams. The dimensions are 175mm x 111mm x 16mm (W x D x H). The threaded holes for attachment of the two junctions, which then must be purchased separately, is 4 x ¼ inch.

For the usual cleaning, there is the greatest of ease: just remove the 14 screws that hold the two Acetal parts and the copper block. After doing this, you can see in the figure the 3 o-rings that serve as seals for the liquid. Here are the details of the grooves for the passage of water.

As seen above, there are 10 channels that maximize the contact and the consequent heat transfer from the (hot) copper block to the (cooler) liquid. See below for the particular of contact areas respectively of the CPU and memory chips:

We note that the contact surfaces are not perfectly smooth. Remember however that the heat transfer is maximized by the thermal pad/paste that acts as an intermediary between the waterblock and the VGA chip on the PCB.
