CPU Waterblock Watercool Heatkiller Tube by Watercool, model 30232

Watercool Heatkiller Tube is a CPU waterblock designed for custom liquid cooling loops. Model 30232 serves as a compact interface between the processor and the cooling circuit, transferring heat from the CPU to the coolant. The product is intended for use with pumps, radiators and tubing in desktop PC watercooling systems and is compatible with HEATKILLER® Tube stands; a decoupling kit is supplied to reduce vibration transmission between the pump and the case bottom.

Advantages

The Heatkiller Tube waterblock combines a compact footprint with direct contact cooling for efficient heat transfer. Precision internal channels optimize coolant flow, while the included decoupling kit uses a soft rubber mixture to prevent pump vibrations from transmitting to the computer case. The design supports straightforward integration into custom loops and is suitable for use with both D5 and DDC pump types when mounted on the HEATKILLER® Tube stand.

Suitable for

• Custom PC liquid cooling loops requiring a compact CPU waterblock
• Systems using HEATKILLER® Tube stands with D5 or DDC pumps
• Desktop builds where vibration isolation between pump and case is required

Key specifications

• Component type: CPU waterblock for liquid cooling loops
• Compatibility: Designed for integration with HEATKILLER® Tube stands and common desktop watercooling components
• Mounting: Stand-mounted configuration with separate decoupling kit for case-bottom installation
• Material characteristics: precision machined contact surface and coolant channels (manufacturer materials unspecified)
• Vibration isolation: soft rubber decoupling elements to reduce transmission of pump vibrations
• Intended use: closed-loop custom cooling with pumps, radiators and tubing

How to use

Install the Heatkiller Tube waterblock onto the HEATKILLER® Tube stand according to the stand manufacturer’s mounting instructions, ensuring proper thermal interface material is applied between the CPU heatspreader and the waterblock contact surface. Fit the decoupling kit between the stand and the computer case bottom to isolate pump vibrations; this uses soft rubber elements that compress to absorb mechanical energy. Connect inlet and outlet tubing to the waterblock ports and integrate with the pump and radiator in a sealed liquid loop, then fill and leak-test the system before powering the PC.

Usage recommendations

Use the decoupling kit when pairing the HEATKILLER® Tube with D5 or DDC pumps to minimize audible and structural vibration. Follow standard liquid-cooling precautions: use compatible tubing and coolant, ensure secure fittings, and perform a thorough leak test. Periodically inspect the decoupling elements for wear and replace them if deterioration is observed.
