Radiators & fans,
matched to the loop, not just the chassis.
Copper-fin multiport radiators in 360 mm and 480 mm formats. 45 mm thickness, 18 FPI, four G1/4″ connection ports per radiator for flexible loop routing. Designed for low hydraulic restriction at typical workstation flow rates, and engineered to pair with EK-Pro 120 mm fans in push or push-pull configurations.

P360
Triple 120 mm — 360 mm long
Three 120 mm fan slots over a 45 mm-thick copper fin core. Sized for compact workstation builds with one or two GPU water blocks on the loop. Fits the 360 mm bracket common in tower workstations.
3 × 120 mm fan compatible · 360 × 120 × 45 mm
P480
Quad 120 mm — 480 mm long
Four 120 mm fan slots over the same 45 mm core. Specified for higher-density GPU workstations or as the second radiator in a parallel loop. Rejects roughly a third more heat than the P360 at the same fan pressure.

Every radiator in this family shares the following.
| Fin material | 99.9% copper, non-louvered, 18 FPI - consistent pressure drop across fan RPM range. |
|---|---|
| Tube material | H90 copper, 2 mm wide · 14 tubes per radiator length. |
| End tanks | H62 brass · corrosion-resistant · no mixed-metal incompatibility with copper blocks. |
| Side plates | Stainless steel · maintains core geometry under lateral chassis clamping forces. |
| Ports | 4 × G1/4″ (2 end + 2 side) · nickel-plated brass plugs included for unused ports. |
| Thickness | 45 mm · fits standard chassis 120 mm fan mounts in single or push-pull configuration. |
| Pressure tested | 1 bar (100 000 Pa) at factory before shipment. |
Not sure which size?
Radiator sizing depends on the combined TDP of the blocks in the loop, the fan operating point, and chassis constraints. Tell us what's in the build and we'll tell you whether P360 is sufficient, whether P480 is the right call, and whether push-pull changes the equation.
