Product information

Description

Watercool HEATKILLER IV BASIC is a compact CPU water block made in Germany from copper, PMMA (transparent acrylic) and stainless steel. With external dimensions of 59 × 66 × 17 mm, it combines a metal cold plate for efficient heat transfer and a transparent top for visual monitoring of coolant flow. The HEATKILLER IV series represents an evolution of Watercool's long-standing cooling design approach, featuring an integrated flow architecture and a focus on balanced performance and ease of installation.

Advantages

The HEATKILLER IV BASIC offers improved cooling performance compared to earlier iterations through a redesigned cooling engine with thinner cold-plate fins that increase surface area without compromising flow rate. The integrated top replaces a separate jet plate design to increase reliability and flow efficiency. A tool-less Easy-Mount system simplifies repeated installations and reduces the risk of faulty mounting. The block is compatible with larger fittings thanks to a 25 mm port distance, and its transparent PMMA top allows visual checking of coolant circulation.

Suitable for

  • Liquid cooling of desktop CPUs in custom water-cooling loops
  • Compact or space-constrained builds requiring a low-profile block (17 mm height)
  • Systems where visual coolant monitoring is desired
  • Setups that benefit from tool-less mounting and frequent maintenance or component swaps

Key specifications

  • Materials: copper cold plate, PMMA transparent top, stainless steel components
  • External dimensions: 59 mm (width) × 66 mm (depth) × 17 mm (height)
  • Integrated cooling engine with thinner fins for increased surface area
  • Improved flow path and integrated jet mechanics for higher flow rate
  • Tool-less Easy-Mount system for repeatable installations
  • Port spacing suitable for larger fittings (25 mm port distance)

How to use

Install the HEATKILLER IV BASIC onto a compatible CPU socket following the manufacturer's mounting instructions and using the Easy-Mount system for initial seating. Connect inlet and outlet tubing to the block's ports, ensuring secure, leak-free fittings compatible with the block's port spacing. Fill and purge the loop according to standard liquid-cooling procedures, check for leaks, and verify coolant flow through the transparent top before powering the system. During operation monitor temperatures and coolant flow regularly and follow general liquid-cooling maintenance practices.

Usage recommendations

Use coolant and tubing compatible with PMMA and copper to avoid material incompatibilities. During filling and maintenance avoid aggressive cleaning agents that can damage the PMMA top; use manufacturer-recommended coolants and soft, non-abrasive cleaning methods. When installing larger fittings, confirm clearance around the ports and tighten fittings to the manufacturer's torque recommendations to prevent leaks.
