## Long description

Watercool heatkiller is a CPU water block made of aluminium with a black and transparent finish, designed for integration into custom liquid cooling loops. The unit measures 70×70×117.3 mm and contains an internal capacity of 0.25 L of coolant. Its purpose is to transfer heat from the processor to the cooling medium, making it suitable for PC water-cooling setups, maintenance and upgrade projects where an aluminium, visually accessible block is required.
Advantages
The aluminium construction provides a stable thermal path and mechanical rigidity while the transparent elements allow visual inspection of flow and coolant condition. A compact footprint (70×70×117.3 mm) and modest coolant volume (0.25 L) make the block compatible with many custom loop layouts and tighter case spaces. The black finish offers a neutral appearance that integrates with a variety of build styles without adding excessive bulk.

Custom PC liquid cooling loops
Processor cooling upgrades and maintenance
Builds requiring a compact aluminium CPU block with visual coolant access

How to use
Install the Watercool heatkiller CPU water block into a compatible water-cooling loop following the case and motherboard CPU-socket mounting guidelines. Ensure proper sealing of fittings and use compatible tubing and connectors. Fill the loop with an appropriate coolant, bleed air from the loop thoroughly, and verify that flow passes through the transparent section so coolant circulation and condition can be observed. Follow standard safety precautions for liquid cooling work, including powering off the system and protecting electrical components during installation and filling.
Usage recommendations
Use a coolant compatible with aluminium components and maintain regular checks for corrosion or deposits. When integrating the block with other metals in a loop, consider corrosion inhibitors or use a coolant formulated for multi-metal systems. Periodically inspect the transparent section for signs of contamination and perform routine coolant replacement according to the coolant manufacturer’s guidance to preserve thermal performance and reliability.
