Watercool Announces New HEATKILLER V PRO and ULTRA Water Cooling Blocks for AMD AM5/AM4 Processors
More than ten years since the introduction of the HEATKILLER IV, Watercool is presenting a new generation of its CPU water coolers with the HEATKILLER V PRO and ULTRA. Developed from the ground up for the latest AMD processors on the AM4 and AM5 sockets, these models complement the existing product line. The proven HEATKILLER IV remains part of the lineup.
Key features of the new HEATKILLER V series include a completely redesigned cooling structure, a new pre-assembled mounting system, and indirect aRGB lighting. Right from its market launch, the HEATKILLER V ULTRA impressed PC Games Hardware and emerged as the top performer in their comparison test. The independent test confirms the development goals of the new generation: high thermal performance with efficient airflow and a cooling structure specifically tailored to current AMD processors.
New Cooling Structure for the Latest Ryzen Processors
The base plate, fin structure, residual base thickness, and airflow guidance were completely redesigned for the HEATKILLER V and optimized for the high heat flux densities of modern Ryzen processors.
The ULTRA version features an exceptionally fine fin structure of 0.15 mm, while the HEATKILLER V PRO uses 0.25 mm fins.
New Mounting System and Indirect aRGB Lighting
The pre-assembled mounting system enables easy installation and ensures precise positioning, a secure fit, and evenly distributed contact pressure.
For uniform indirect lighting, the HEATKILLER V ULTRA features 43 low-power aRGB LEDs, arranged in a way that largely prevents visible individual light spots.
Halnziye HY-P17 Included
The HEATKILLER V ULTRA comes with 1 gram of Halnziye HY-P17 high-performance thermal paste for an efficient thermal interface between the processor and the cooler base.
Full-Metal Versions to Follow in October
At launch, the HEATKILLER V will initially be available in the announced acrylic versions. The full-metal versions of the HEATKILLER V series will follow in October 2026.
The black acrylic version is available for pre-order now and is expected to ship no later than September 25, 2026.
