The HEATKILLER® GPU-X³ Core is a GPU-only cooler with features usually only known from full cover coolers. E.g., this series is fully compatible with our GPU-X Multi-Links. The LT version even offers the possibility to integrate the VRMs into the cooling loop.

    Extraordinary cooling performance, high flow rates, child's play mounting, and superior design – all these features make the HEATKILLER® IV the most powerful HEATKILLER® ever.
  • GPU backplates

    The HEATKILLER® GPU Backplates improve both the looks and the mechanical rigidity of the graphic card. Being made from polished stainless steel, the backplates are true eye catchers as well.
