Top quality high-end CPU water block with a nickel-plated copper cold plate and a decorated top made from acetal/POM. Compatible with AMD socket AM4 and AM5.

From enthusiasts for enthusiasts, our HEATKILLER® series CPU water blocks are among the best performing and most popular CPU blocks on the market. Since its introduction in 2001, we have continuously enhanced and improved the series. The HEATKILLER® IV is the most comprehensive and recent iteration of the franchise.

It offers up to 3°C better cooling performance compared to its predecessor, a better flow rate thanks to a bigger jet plate nozzle and channel layout that reduces clogging, and a tool-less Easy-Mount-System. It is also compatible with extra large fittings due to a 25mm port distance.

New cooling engine and optimized flow paths. Throughout all developments, the cooling engine took the biggest evolutionary step. We gave the cold plate significantly thinner fins, resulting in a larger surface area and better heat dissipation, while ensuring that the flow rate is not impacted. We dropped the separate jet plate design and integrated its mechanics directly into the top. This new technology improves performance, flow rate, and reliability.

The Heatkiller IV Easy-Mount features 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 for the installation bolts, making a faulty installation almost impossible.

The design is also 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, we took care of our customers’ requests and made the block compatible with fittings of up to 19mm width.
