Radiatore EK Water Blocks ottone rame acciaio inox nero 130x300x44mm

The EK-Quantum P Series X-Flow Surface radiator is a 44 mm thick liquid-cooling radiator designed for PC systems. Constructed with copper tubes, high-grade non-louvered copper fins, extruded aluminum end caps and stainless-steel side plates with a matte black finish, it supports eight G1/4" threaded ports (four on each end) for flexible crossflow routing. The radiator is compatible with standard 120 mm, 25 mm-thick fans and includes mounting screws and hex keys for installation.

Advantages

The radiator offers improved thermal performance compared with its predecessor due to an optimized core and enhanced fin structure, delivering up to 10% better core-to-core performance. Sixteen 2 mm-wide copper tubes across the full length and 18 FPI fin density balance thermal transfer and air resistance to maintain efficiency even at low fan speeds. Its modular multiport design allows sixteen different tube routing combinations while low flow restriction protects pump performance and enables multiple radiators on a single pump. Durable materials and a rigid construction provide a premium finish and straightforward disassembly for modification.

Suitable for

• Custom liquid-cooled desktop PCs
• Multi-radiator cooling loops driven by a single pump
• Systems requiring low fan speed, low-noise cooling
• Modding projects and radiator repainting or modification

Key specifications

• Dimensions: 130 × 300 × 44 mm
• Material: copper tubes and fins, extruded aluminum end caps, stainless-steel side plates
• Tube count: 16 copper tubes (2 mm width) along radiator length
• Fin density: 18 fins per inch (FPI)
• Ports: eight G1/4" threaded connection ports (four per end)
• Fan compatibility: 120 mm fans, 25 mm thickness
• Finish: matte black fins, semi-gloss black side plates, contrasting silver aluminum end caps

How to use

Install the radiator in your case using the supplied M4 screws and the included hex keys, mounting standard 120 mm fans (25 mm thickness) in push, pull, or push/pull configurations as preferred. Configure the G1/4" ports using the modular plugs and adapters to create the desired inlet/outlet routing; the crossflow design permits multiple connection layouts. When fastening fans or securing the radiator to the case, use the supplied screws where possible—M4 compatibility allows longer screws if required but take care to avoid contacting internal fins.

Recommendations

Use low-impedance fans and ensure your pump (for example D5 or DDC class) provides adequate flow for multi-radiator loops. For best results, pair the radiator with sealed-edge frame 120 mm fans, follow EK-Matrix7 spacing when combining with other EK components for clean tubing runs, and consider push/pull fan setups to maximize cooling performance at lower fan speeds.
