Design and Functionality: CPU Block

The CPU block is of oval shape. Its base of made of solid copper and the top part – of acrylic:

The block weighs 380g. There are two fittings with ~5mm internal diameter on both sides of the oval and the internal structure consists of rectangular copper pins:

The acrylic lid is tightly pressed to the base with four screws and a hermetic rubber ring:

Looks like someone tightened one of the screws too much, because we can see a crack in acrylic:

Luckily, there was no leakage in this spot and the defect didn’t affect the cooling efficiency test results in any way.

The CPU water block features a true mirror-shining base:

It is ideally even, which we have checked with the thermal compound print on the glass surface and later on the CPU heat-spreader.
