# 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.

## Two sizes, one fin profile.

### Triple 120 mm – 360 mm long

P360

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

### Quad 120 mm – 480 mm long

P480

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.

4 × 120 mm fan compatible · 480 × 120 × 45 mm

## Every radiator in this family shares the following.

| Specification | Value |
| --- | --- |
| 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. |
