Finished in black, model WACP-545 provides direct liquid cooling for the CPU to reduce operating temperatures and maintain stable performance under load. Intended for custom liquid cooling loops in workstations and servers, it offers reliable heat transfer and compatibility with Xeon sockets; suitable for overclocking, sustained high workload and quiet cooling setups.

## Long description

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.
Usage 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.
