Phanteks 420mm Copper Radiator White

This Phanteks radiator uses an all-copper core with T2 copper fins and H90 brass tubing for heat dissipation. The 420mm length fits three 140mm fan positions in compatible cases. Integrated 16mm EZ-Fit fittings accept both hard and soft tubing without extra parts. The white finish matches light-themed builds.

Check Case Clearance and Fan Mounts

Verify that your chassis provides 470mm of linear space for the 420mm radiator plus fan thickness. Confirm M4 thread holes align with 25mm or 30mm fans you plan to use. Ensure the 30mm radiator depth plus fans does not interfere with motherboard components or drive cages. The integrated fittings add 16mm to the port height.

EZ-Fit Fittings Remove Extra Parts

The bundled 16mm EZ-Fit fittings thread directly into the H59 brass inserts, so separate compression fittings are not required. Included M4 screws secure 25mm or 30mm fans to the steel frame. Brass construction on chambers and threads resists corrosion in mixed-metal loops. White side panels keep the aesthetic consistent.

Questions about this item

Does the Phanteks PH-GEF-RAD423_WT include the 16 mm EZ-Fit fittings or must I buy them separately?

The radiator ships with integrated 16 mm EZ-Fit fittings that work with both hard and soft tubing, so no extra fittings are required.

Should I choose the 420 mm 30 mm thick version over a thinner model for my build?

The 30 mm thickness and 19 FPI copper core give higher thermal capacity, making this version better suited for multi-GPU or heavily overclocked loops.

What does the 420 mm 30 mm specification mean once the radiator is installed in a real loop?

It provides a 470 x 140 x 30 mm cooling surface with M4 threads for 25 mm or 30 mm fans, and the included screws let you mount fans immediately.
