Liquid cooling kit Thermaltake CL-W253-CU12SW-A

Thermaltake Pacific C360 DDC Soft Tube Water Cooling Kit (model CL-W253-CU12SW-A) is a complete liquid cooling combo designed for custom PC builders who need a ready-to-install loop with 5V ARGB motherboard synchronization. The kit includes a Pacific C360 360mm slim copper radiator, Pacific PR15-DDC pump/reservoir combo with integrated 200 ml reservoir, Pacific W4 ARGB CPU water block, three Pure 12 ARGB Sync 120 mm radiator fans, a bottle of T1000 Transparent Coolant (Pure Clear), six 1/2" ID x 3/4" OD compression fittings, two G1/4 90° adapter fittings, two meters of V-Tubler 4T transparent soft tubing (1/2" ID x 3/4" OD), an ARGB LED controller and all necessary accessories. The components are compatible with 5V RGB-capable motherboards from Asus, Gigabyte, MSI and ASRock and suit a wide range of mainstream CPU sockets.

Advantages

The kit offers a high-density copper fin 360 mm radiator with brass tanks and stainless steel side panels for durability and efficient heat dissipation, a DDC pump integrated into a clear reservoir for compact and reliable flow, and a copper-base W4 ARGB water block with 0.15 mm internal fins and nickel plating for improved thermal transfer and corrosion resistance. Included Pure 12 ARGB Sync fans use hydraulic bearings and compression blades for good static pressure and are controllable via motherboard RGB software or the supplied controller. All fittings use standard G1/4" threads and the included compression fittings and 90° adapters simplify tube routing and leak-resistant assembly.

Suitable for

• Custom water-cooled gaming and workstation PCs
• High-performance CPU cooling for overclocking and sustained loads
• Builders who want 5V ARGB synchronization with motherboard RGB software
• Small-to-medium custom loops using 360 mm radiator configuration

How to use

Install the Pacific C360 radiator in a case position that supports 360 mm radiators and mount the three 120 mm Pure ARGB fans for exhaust or intake as preferred. Fit the Pacific W4 ARGB water block onto the CPU using the included universal mounting hardware and thermal paste. Mount the PR15-DDC pump/reservoir in a secure location and connect inlet/outlet ports to the radiator and water block using the supplied soft tubing and compression fittings; use the 90° adapters where tighter routing is required. Fill the loop with T1000 Transparent Coolant, purge air by running the pump at low speed until stable flow and no air pockets remain, then check all connections for leaks before normal operation.

Recommendations

For reliable long-term operation, run an initial leak test outside the system or with non-powered components, follow manufacturer guidelines for coolant mixing and maintenance, and periodically check coolant level and fittings. Use motherboard 5V ARGB headers or the included ARGB controller to manage lighting, and ensure the pump receives appropriate power and airflow for optimal performance.
