Radiator EK Water Blocks 3831109838532 — Brass/Copper/Stainless steel, 145×325×44 mm, black
EK Water Blocks EK-Quantum Surface P series radiator with a 44mm thickness is engineered for a balance of high thermal performance and low noise across the entire fan speed range. The radiator features four G1/4" threaded connection ports plus an additional G1/4" port on the end tank for convenient draining and air bleeding. Eighteen 2mm-wide copper tubes run along the radiator length to ensure optimal coolant flow, while high-grade non-louvered copper fins at 18 FPI provide effective heat transfer with low air resistance. The radiator is finished with extruded aluminum end caps in contrasting silver, stainless-steel side plates coated in semi-gloss black, and fins with a matte black high-conductivity coating.
The EK-Quantum Surface P offers multiport flexibility for versatile loop routing and an extra end-tank port for easy draining and air removal. Its internal design minimizes flow restriction, allowing the use of a single pump for multiple radiators and reducing stress on the cooling loop. The 18 FPI fin density and 2mm copper tube arrangement deliver strong thermal transfer even at low fan speeds, and compatibility with standard 140mm, 25mm-thick fans enables Push/Pull configurations for increased cooling capacity. Modular construction and standardized EK-Matrix7 dimensions simplify disassembly, modding, and integration with other EK components.
Install the radiator in your case using the supplied M4 screws: M4x5 mm for direct case mounting and M4x30 mm for mounting 25 mm thick 140 mm fans. Configure tubing using the G1/4" ports to match your loop layout; the extra end-tank port facilitates draining and air bleeding. For increased cooling performance, install fans in a Push/Pull arrangement. Follow standard liquid-cooling assembly procedures: ensure secure fittings, leak-test the loop before powering the system, and use recommended coolant types.
Use the included screws when possible to avoid accidental damage to the core. For quieter operation and efficient thermal performance, pair the radiator with low-speed sealed-edge 140 mm fans and consider adding multiple radiators to a loop powered by a single D5 or DDC pump if needed. When planning aesthetic or tubing layout, use EK-Matrix7-compatible components for cleaner parallel tube runs.
