Our HEATKILLER® series CPU water blocks are some of the best performing and most popular CPU blocks on the market. Since its introduction in 2001, we continuously enhanced and improved the series. The HEATKILLER® IV is the most comprehensive and recent iteration oft he franchise.

Better flow rate thanks to bigger jet plate nozzle and channel layout less clogging
Tool-less Easy-Mount-System
Compatible with extra large fittings thanks to 25mm port distance

New cooling engine and optimized flow paths
Through all developments, the cooling engine took the biggest evolutionary step. We gave the cold plate significantly thinner fins, which results in a larger surface and better heat dissipation. At the same time, we made sure that the flow rate isn’t impacted by this.
We dropped the separate jet plate design, but integrated its mechanics directly into the top. This new technology improves performance, flow rate, and reliability.
Heatkiller IV Easy-Mount, premium manufacturing, Made in Germany
We developed the revolutionary Easy-Mount –System to simplify the installation process. After the first installation, the block can be installed and uninstalled completely tool-less. The system also provides a fixed stop of the installation bolts. A faulty installation is almost impossible with this system.

But the design should also be worthy of a WATERCOOL product. Only the highest quality raw materials combined with the most cutting edge manufacturing technologies make a true HEATKILLER IV. As a final touch on the design , why took care of our customers’ requests and made the block compatible with fittings of up to 19mm width.
