The HEATKILLER V ULTRA is the consistent evolution of our legendary HEATKILLER IV CPU water block, developed specifically for current AMD processors on the AM4 and AM5 sockets.
At its core is an entirely newly developed cooling structure, engineered for high thermal performance and particularly efficient heat transfer.
Ultra-Performance bottom plate designed for maximum cooling performance and high flow rate
Modern AMD processors place high demands on a CPU water block. High heat flux densities and the position of the heat-generating areas beneath the heat spreader call for a precisely tuned cooling structure.
This is exactly where the HEATKILLER V ULTRA comes in. Cooling base, fins, residual base thickness, and flow guidance form a perfectly matched unit, purpose-built for high heat transfer combined with efficient flow.The base plate features an extremely fine fin structure of just 0.15 mm (Pro: 0.25 mm). Cross-slots improve the deformation of the base plate and ensure optimal contact between the heat spreader and the cooler base.
The result is a CPU water block designed for high-performance Ryzen processors and demanding high-end systems.
Easyinstallation thanks to the pre-mounted mounting System
With the HEATKILLER V ULTRA, it's not just raw performance that counts. Mechanical precision, even contact pressure, and reliable mounting are equally decisive.
The pre-mounted mounting system ensures precisely defined positioning of the cooler, a fixed stop on the processor, and easy installation. The individual components are manufactured to tight production tolerances and precisely matched to one another.
As with all our HEATKILLER products, the V ULTRA relies on carefully selected materials and premium-quality workmanship.
Indirect illumination thanks to aRGB PCB
The HEATKILLER® V ULTRA is illuminated by 43 low-power aRGB LEDs mounted on a specially developed PCB. Their positioning was deliberately chosen to illuminate the cooler evenly and indirectly, largely avoiding visible points of light.
The modular cable makes it possible to use the cooler without illumination.
High-performance thermal paste included
To let the HEATKILLER V ULTRA unfold its full cooling potential, the multi-award-winning Halnziye HY-P17 high-performance thermal paste is included in the package. It perfectly complements the HEATKILLER V for CPU series and ensures efficient heat transfer between the processor and the cooler base.
Designed and manufactured in Germany
From design through manufacturing to final assembly, the HEATKILLER® V ULTRA is created at our facility in northern Germany. We place particular emphasis on high cooling performance, carefully selected materials, and precise manufacturing. The result is a CPU water block in which performance, quality, and workmanship all take center stage equally.
