Radiator EK Water Blocks Quantum Surface P360M Black 130mm 405mm 44mm

The Radiator EK Water Blocks Quantum Surface P360M Black 130mm 405mm 44mm is a high-performance liquid-cooling radiator designed for quiet operation and efficient heat dissipation. With a thickness of 44 mm and a black matte-coated fin surface, the Surface P series combines an improved core design and high-grade materials to deliver better thermal performance and low flow restriction for custom PC cooling loops.

Advantages

The Surface P radiator offers four G1/4" threaded ports plus an additional G1/4" port on the end tank for easy draining and air bleeding, sixteen 2 mm-wide copper tubes along the full radiator length for optimal coolant flow, and non-louvered copper fins at 18 FPI for a balance of thermal transfer and low air resistance. New core and fin geometry improve core-to-core performance by up to 10% compared with the predecessor model. Thick extruded aluminum end caps, stainless-steel side plates with semi-gloss black paint, and a black matte fin coating provide mechanical rigidity and a premium finish.

Suitable for

• Custom PC liquid-cooling loops requiring a 360 mm radiator
• Low-noise setups where efficient cooling at low fan speeds is desired
• Multi-radiator loops using a single pump (D5 or DDC)
• DIY modding and painting due to modular design and easy disassembly

How to use

Install the radiator in your case using the supplied M4 screws and mount standard 120 mm fans in push, pull, or push/pull configurations. Connect tubing to the G1/4" ports according to your loop plan; the modular plugs and extenders in the end caps allow flexible port orientation for optimal tube routing. Use the dedicated end-tank G1/4" port to drain the loop and bleed air. Ensure fans are mounted with sealed-edge or similar frames for best performance and avoid overtightening screws to prevent contact with the fins.

Recommendations

For balanced cooling and low noise, run the radiator with low- to medium-speed fans and consider a push/pull configuration only when additional thermal headroom is needed. Use compatible EK Matrix7 products for consistent port alignment and cleaner tubing runs, and prefer the supplied screws or standard M4 screws to avoid installation issues.
