Watercool launches new Heatkiller V Ultra and Pro CPU blocks

Watercool is expanding its HEATKILLER lineup with two new CPU blocks for AM4 and AM5, the HEATKILLER V Ultra and the HEATKILLER V Pro. Both models introduce a redesigned fin layout and updated baseplate structure aimed at improving contact and flow on modern Ryzen processors.

The HEATKILLER V Ultra is the flagship model. Watercool has redesigned the fin layout and baseplate for AM4 and AM5, using 0.15mm fins and a revised flow path to improve contact under Ryzen’s hotspot layout. Cross‑slots in the base allow the copper to flex slightly under mounting pressure, helping it sit flatter against the CPU. The Ultra also features a nickel‑plated copper base, a pre‑assembled mounting system and a dedicated ARGB PCB with 43 LEDs positioned for indirect illumination. The lighting cable is modular, allowing the block to be used without RGB if preferred.

The HEATKILLER V Pro follows the same design philosophy, using the same 0.15mm fin structure but paired with a bare copper base rather than a nickel‑plated one. Watercool describes the Pro variant as tuned for maximum flow while still benefiting from the updated fin geometry and cross‑slot contact improvements. Like the Ultra, it ships with the new mounting system and includes Halnziye HY‑P17 thermal paste in the box.

Both blocks are manufactured in Germany, from machining through to final assembly, and use a mix of aluminium, PMMA and copper across the frame and top. Pricing lands at €179.95 for the Ultra model and €159.95 for the Pro.
