The Heatkiller 3.0 is the latest revision in Watercool’s successful CPU water block series. The Heatkiller has a very geometric aesthetic, with many angles punctuated by stainless steel and copper materials. It is the only block in the roundup that has copper visible to the front, though the copper does continue through as it forms the base. The block’s body is sculpted from one piece solid pure copper and to prevent tarnishing, a special clear lacquer is treated. The HK 3.0 is also available in other finishes such as nickel, chrome, and black acetal to suit just about any aesthetic preference, so in terms of style it is probably the most versatile of the bunch.
The cold plate is also made out from 2mm thick copper with 1mm depth straight micro fins and water channels. This leaves the cold plate only 1mm thick at the center; this is what apparently helps to produce improved cooling performance for the Heatkiller. The stainless steel distributor plate is designed to allow coolant to flow evenly across the CPU.
The base plate is attached to the body by six countersunk screws from the bottom. The Heatkiller 3.0 is compatible with any standard G1/4” threaded barbs from 1/4” (6mm) – 1/2″ (13mm) in size. However, it is limited to 1/2″ (13mm) ID and 5/8” (16mm) OD compression fittings. Further, you may also find it difficult to use 3/4″(16mm) hose clamps on the barbs due to the tight spacing of them.
Let’s move onto the next block.
