The HEATKILLER V Water Cooler for AMD’s High-End Big-Navi Graphics Cards Generation Announced

“The focus of our development has always been to improve the deliverable performance.” (Rico Weber, WATERCOOL CEO, Sep.2020). This quote marked the beginning of the development of the new HEATKILLER V VGA cooler. In addition to an increase of performance, the focus also lay on improvements in handling and durability. The HEATKILLER VGA coolers, known for their outstanding workmanship, have also been visually enhanced. In the latest revision for AMD graphics cards of the RX 6800/6900XT series, the HEATKILLER V has been further optimized.

The inflow to the cooling structure has been completely reworked. It now is placed with a vertical offset above a second level. The inlet and outlet channels cross each other, but are spatially separated from each other. The new design allows a symmetrical arrangement of the cooling channels. The advantage of the symmetrical design is a steady flow through the heat sink. Dead zones and hotspots are thus effectively avoided. At the same time the windage is reduced. The HEATKILLER V for RX 6800/6900XT features a vertical cooling structure, which significantly improves the cooling performance even more. The enlarged cooling surface ensures exceptionally low GPU temperatures. To reduce turbulences, all cooling channels were manufactured in a rounded design.

  • Dual layer flow
  • Improved vertical cooling structure
  • Refined cooling structure
  • Increased flow
  • Symmetrical cooling design
  • Screwless cover
  • aRGB as standard
  • Insulating spacers made of high performance plastic (Peek)
  • Stainless steel reinforced threads
  • CNC cut thermal pads
  • Kryonaut thermal compound

With the new design of the HK V there are no more screws in the visible area, which gives the cooler a very clean and unique look. The two acrylic nickel versions also feature integrated aRGB illumination. Here Watercool uses an LED strip with an immensely high density of 144 LEDs per linear meter. This unusually high number was intended to provide adequate illumination.

The experience gained in the industrial sector brought the high-performance synthetic material “Peek” to attention. This material provides one hundred percent insulation between the cooler block and the graphics card’s circuit board. To avoid issues with the threads in the Plexiglas, Watercool inserted a square nut made of stainless steel.

We used of our technical capabilities and designed the backplate for the AMD cooler in such a way that no electronic components are visible anymore. The backplate completely covers the upper part of the PCB and thereby builds a closed unit with the cooler. Meanwhile the aRGB functions remain completely unaffected and further enhance the coolers appearance with the new High-Luminous LEDs.

With the Pre-cut thermal the installation has never been easier before. The award-winning Thermal Grizzly Kryonaut thermal paste ensures the heat transfer from the GPU to the cooler. Even the maintenance has been thought of. By loosening two screws, the stainless steel respectively aluminium bezel can be removed.

Announced options:

  • Backplate
  • Vertical connection terminal (Plexiglas GS, Acetal

There will be optional modifications for the HEATKILLER V VGA. Besides the obligatory backplate, WATERCOOL also thought about modding with a vertical connection terminal made of Plexiglas GS. The HEATKILLER V for RX 6800/6900XT is available in different configurations, suitable for AMD’s reference design.
You can choose from a number of different variants. There are Acetal copper versions as well as Plexiglas GS versions with a nickel-plated copper bottom and bright aRGB stripes. The prices vary and start from 134,90 € without optional accessories.
