Watercool HEATKILLER IV PRO (AMD, AM4, AM5) BLACK COPPER PVD CPU Water Block, G1/4 (18090)

Our latest HEATKILLER IV Black Copper PVD water cooler features a high-quality, black, diamond-like carbon coating applied using a modern plasma process (Diamond Like Carbon, DLC). This extremely hard and wear-resistant surface provides a stunning deep black appearance while offering optimal protection and long-lasting quality.

• Up to 3°C better temperatures compared to the previous model


• Increased flow rate thanks to a larger nozzle and collection channel, resulting in fewer blockages.


• tool-free Easy Mount system


• Extra large connectors thanks to 25mm spacing

New cooling structure and optimized airflow

Our cooling structure underwent the most significant redesign. We equipped the cooler with considerably finer fins to provide a larger surface area and thus better heat dissipation. We also ensured that the fins were designed in such a way that the airflow was not compromised.

Compared to the previous model, we eliminated the nozzle plate and integrated it directly into the lid. This innovative design allowed us to increase performance, improve airflow, and optimize reliability.

Heatkiller IV Easymount, top quality workmanship, Made in Germany

To make installation as easy as possible, we developed the Easy-Mount system. This allows the cooler to be mounted or dismounted without tools at any time after initial installation. The mounting system is further enhanced by a fixed stop on the mounting bracket, virtually eliminating the possibility of incorrect installation.
But the design, too, should be befitting a Watercool product. Superior manufacturing techniques, combined with the finest materials, result in our Heatkiller IV cooler. To best showcase the opulent design, we listened to our customers' wishes and accommodated connection types up to 19mm.
