From enthusiasts for enthusiasts. The water coolers of the HEATKILLER CPU series 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 series has been continuously improved and optimized. The HEATKILLER IV 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 previous model, these changes have increased cooling performance by up to 3 °C. Flow rate is positively influenced as well, supported by large-volume collection channels. The HEATKILLER IV PRO 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 increases 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 PRO now features 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 defines the clamping forces, making incorrect installation practically impossible. The HEATKILLER IV PRO is a product "Made in Germany." Manufacturing takes place on a state-of-the-art CNC machine park at Watercool's company location.
