Phanteks Glacier EZ-Fit 420mm Radiator

The Phanteks PH-GEF-RAD423_BK is a 420mm copper radiator designed for custom water-cooling loops. It integrates 16mm EZ-Fit fittings that accept both hard and soft tubing without extra parts. The all-copper core uses T2 copper fins and H90 brass tubes for efficient heat transfer. A steel outer frame adds rigidity for long-term durability in DIY builds.

Suits builders wanting integrated fittings

This radiator fits loops that use 16mm OD tubing and standard M4 fan mounts. It is not for systems that require larger or smaller fitting sizes, or for builders who prefer separate compression fittings. Cases without 420mm mounting space cannot accommodate the 470mm overall length. Loops designed for aluminium cores should avoid mixing metals with this copper construction.

19 FPI high-density copper fin stack

The 19 fins-per-inch arrangement maximises surface area across the 470x140x30mm core to dissipate heat under heavy loads. Combined with pure copper fins and brass water chambers, this fin density is the primary factor that determines cooling capacity in a given airflow configuration.

商品問答

Should I pick the 420 mm 30 mm thick radiator or a thinner model for my loop?

The 420 mm length with 30 mm thickness gives a 470x140x30 mm core that fits standard triple-fan mounts while providing more coolant volume than slimmer options.

What does the 19 FPI fin density actually deliver inside a running PC?

Nineteen fins per inch create a high surface area that moves heat from the copper fins into the airflow efficiently, even when fans run at lower speeds.

How do the integrated 16 mm EZ-Fit fittings limit tubing choices?

The built-in 16 mm fittings accept both hard and soft tubing with a 16 mm outer diameter, so no separate compression fittings are required.
