Watercool HEATKILLER V PRO and ULTRA CPU Cold Plates Launch

Watercool has released the HEATKILLER V, marking the first major update to its flagship CPU cooling line in more than ten years. This refresh matters because it introduces a thinner cold plate design that should improve thermal contact with modern processor surfaces. Buyers looking for high-performance liquid cooling components now have a new option that prioritizes minimal base plate thickness.

New split cold plates feature thinner fins for AMD AM4 and AM5

The HEATKILLER V is a split cold plate designed specifically for AMD desktop platforms. It supports both the older AM4 socket and the current AM5 socket. Watercool offers two distinct models to target different cooling needs: the HEATKILLER V PRO and the HEATKILLER V ULTRA. Both versions feature a redesigned internal structure with new fins and flow channels to optimize coolant movement.

Specifications

• Base Plate Thickness: 0.25mm (PRO), 0.15mm (ULTRA)
• Socket Compatibility: AMD Socket AM4 / AM5
• LED Configuration: 43 low-power ARGB LEDs
• Cover Material (Initial): Transparent Acrylic
• Cover Material (Later): Full Metal

The primary difference between the two models lies in the density of the copper fins. The PRO variant uses a 0.25mm fin pitch, while the ULTRA model pushes this down to 0.15mm for potentially higher heat transfer. Both units come equipped with 43 low-power ARGB LEDs integrated into the top cover. The initial launch includes a transparent acrylic cover that allows the lighting effects to be clearly visible.

Watercool plans to expand the product line later this year with a full metal cover version. This metal variant is scheduled to arrive in October 2024. The current acrylic models are available globally starting from the announcement date in late August. The pricing for the initial release is set at 159.95 EUR (around $186) for the PRO model and 179.95 EUR (around $210) for the ULTRA model.

The HEATKILLER V marks a notable update to the series, which has long been popular among custom loop builders. The introduction of the ULTRA variant with its ultra-thin 0.15mm fins suggests a focus on maximizing thermal performance for high-end AMD CPUs. Previous HEATKILLER generations were reviewed to contextualize the design evolution of this new release. The new cold plates are now available for purchase, giving users a choice between standard and high-density fin configurations.
