CPU water block Watercool Heatkiller IV Pro for Intel Xeon, black (WACP-545)

Watercool Heatkiller IV Pro for Intel Xeon in black is a CPU water block engineered for direct liquid cooling of Intel Xeon processors. Designed for installation in custom water cooling loops in workstations and servers, this block delivers efficient heat transfer from the CPU to the coolant to lower operating temperatures and preserve performance stability during sustained loads. The Heatkiller IV Pro is intended for systems where reliable thermal control, low noise and compatibility with Xeon sockets are required.

Advantages

The Heatkiller IV Pro features a solid copper cold plate and fin geometry optimised for energy transfer to the coolant, providing improved thermal conductivity compared with air cooling. A durable black finish offers corrosion resistance and a neutral appearance that integrates into professional builds. Its construction supports quiet operation by enabling efficient heat removal at lower pump speeds and it is suitable for continuous use in high-load environments.

Suitable for (tasks / use cases)

• Workstations running multi-threaded professional software (rendering, simulation, CAD)
• Servers and compute nodes requiring sustained thermal management
• Custom liquid cooling loops in quiet or space-constrained builds
• Systems where stable temperatures under long-duration loads are important

Key specifications

• Compatibility: Intel Xeon socket support
• Material: copper cold plate with black finish
• Cooling type: direct liquid cooling for custom loops
• Mounting: designed for secure attachment in workstation/server CPU sockets
• Design focus: high thermal conductivity and low flow restriction

How to use

Install the Heatkiller IV Pro into a custom liquid cooling loop following the motherboard and chassis manufacturer instructions for Xeon CPU water block mounting. Apply a thin, even layer of thermal interface material between the CPU heatspreader and the block cold plate. Connect inlet and outlet fittings to the loop tubing, ensure all fittings are tightened, and perform a pressure and leak test before powering the system. Configure pump and fan speeds to achieve the desired balance of temperature and noise.

Recommendations

Use corrosion-inhibited coolant and follow routine maintenance: inspect fittings and tubing periodically, flush and replace coolant according to system requirements, and verify mounting torque after initial thermal cycles. These steps help maintain consistent thermal performance and prolong component life.
