Water block Watercool Heatkiller IV Basic — copper/nickel/stainless steel, 59×66×17 mm

Watercool Heatkiller IV Basic is a compact CPU water block engineered for custom liquid cooling loops. Constructed from copper with nickel plating and stainless steel components, and featuring an ACETAL/POM decorated top, the block measures 59 × 66 × 17 mm and is manufactured in Germany. It is designed to transfer heat from CPUs to the coolant efficiently and is compatible with Intel sockets 1150, 1200 and 1700. The product includes design improvements from the HEATKILLER IV series such as a refined cooling engine with thinner coldplate fins, integrated jet mechanics in the top, and an Easy-Mount system for simplified installation.

Advantages

The nickel-plated coldplate and refined fin geometry increase heat dissipation surface while preserving flow rate, delivering improved thermal performance versus previous iterations. The integrated jet mechanics and optimized flow paths reduce internal resistance for better coolant circulation. The Easy-Mount system enables largely tool-less installation after the initial assembly and includes a fixed stop for the mounting bolts to minimise installation errors. Compatible top and port spacing allow the use of larger fittings where space permits.

Suitable for

• Custom PC water-cooling loops for desktop Intel systems
• Enthusiast and mid-range builds requiring compact CPU cooling
• Component-level cooling where a small footprint block is preferred

Key specifications

• Materials: copper coldplate with nickel plating, stainless steel elements, ACETAL/POM top
• Dimensions: 59 × 66 × 17 mm
• Socket compatibility: Intel 1150, 1200, 1700
• Port spacing designed to accept larger fittings (port center distance approx. 25 mm)
• Manufacturing: CNC-machined components, assembled and tested in Germany
• Weight (package): approximately 350 g

How to use

Prepare the CPU and motherboard according to manufacturer instructions and apply an appropriate thermal interface material to the processor surface. Install the Heatkiller IV Basic using the Easy-Mount system; after the initial installation and alignment, subsequent installs and removals can be performed largely without tools. Ensure fittings and tubing are compatible with the block’s port spacing and tightened to manufacturer torque recommendations. When mounting to LGA1700 sockets, use a compatible backplate as recommended to prevent bending of the socket area.

Recommendations

Use high-quality coolant and compatible fittings to maintain optimal flow and avoid contamination. Periodically inspect seals and fittings for leaks and service the loop according to coolant manufacturer guidance. For LGA1700 installations, pair the block with a compatible backplate to ensure reliable mounting and even pressure distribution.
