The Heatkiller IV Pro AMD - Acrylic Clean from Watercool is a highly advanced AiO water cooler specifically designed for AMD processors. This Clean variant features a uniform design without a silver decorative trim around the G1/4-inch ports, giving it a modern and elegant appearance. The Heatkiller series is known for its outstanding cooling performance and quality, developed and produced in Germany. The Heatkiller IV represents the most comprehensive advancement of the series, offering significant improvements in cooling structure. With optimized micro fins and improved flow dynamics, it creates a larger contact area for the cooling medium, resulting in enhanced cooling performance of up to 3 degrees Celsius compared to previous models. These features make the Heatkiller IV Pro an ideal choice for high-performance systems and also suitable for lower-powered pumps.
- Optimized cooling structure with refined micro fins for better heat transfer
- Increased cooling performance of up to 3 degrees Celsius compared to previous models
- Large-volume collecting channels for improved flow
- High-quality materials: nickel-plated copper and transparent acrylic cover

3. Watercool Heatkiller IV PRO AMD CPU Water Cooler - Acetal
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.

For enthusiasts, by enthusiasts. The HEATKILLER CPU series water coolers are among the most well-known and best-selling CPU water coolers. Since the launch of the first HEATKILLER CPU water cooler in 2001, the model range has been continuously improved and optimized. The HEATKILLER IV BASIC represents the most extensive development to date. The cooling structure has undergone the most significant revision. Thanks to refined micro fins, the cooling medium now has a much larger contact area with the cooler. The flow behavior has also been optimized. Compared to the predecessor model, these changes have increased cooling performance by up to 3 °C. The flow rate is positively affected as well, supported by large-volume collection channels. The HEATKILLER IV BASIC features a true high-flow design, making it the perfect partner for lower-performance pumps. The new cooling structure completely eliminates the need for a nozzle plate. This omission enhances the passive reliability of the cooler, as fewer dirt particles can accumulate in the cooling structure with this design. There have also been significant improvements in the equipment. The HEATKILLER IV BASIC now includes a convenient Easy-Mount system. After the initial installation, the cooler can be mounted or dismounted at any time without tools. The motherboard does not need to be removed for this. The mounting system provides the necessary clamping forces, practically eliminating the possibility of incorrect installation. The HEATKILLER IV BASIC is a product "Made in Germany." Manufacturing takes place on a state-of-the-art CNC machine park at Watercool's company location.
