New cooling engine and optimized flow paths Through all developments, the cooling engine took the biggest evolutionary step. Watercool gave the cold plate significantly thinner fins, which results in a larger surface and better heat dissipation. At the same time, Watercool made sure that the flow rate isn't impacted by this. Watercool 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 Watercool 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.
