Our HEATKILLER IV Black Copper PVD water cooler features a high-quality, black, diamond-like carbon (DLC) coating. This coating is applied using a modern plasma process called Diamond Like Carbon (DLC). This extremely hard, wear-resistant surface provides an impressive, deep black look and offers optimal protection and long-lasting Quality. 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. 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.
