Radiator PHANTEKS Glacier EZ-Fit 420RAD-30 420mm black

PHANTEKS Glacier EZ-Fit 420RAD-30 is a 420 mm liquid-cooling radiator in black, engineered for custom PC water-cooling loops and high-performance cooling builds. The radiator offers a 420 mm mounting length that accommodates multiple 120 mm fans and fits enclosures and cooling configurations designed for 420 mm radiators. Constructed to balance cooling surface area and low airflow resistance, this radiator is intended to improve heat dissipation from CPUs, GPUs and other heat-generating components in custom cooling systems.

Advantages

The radiator combines a long 420 mm form factor with a fin and tube structure optimized for efficient thermal transfer while maintaining compatibility with standard 120 mm fan mounting arrays. Its black finish integrates visually with most PC builds and the construction supports common fittings used in custom water loops. The design aims for a balance between radiator thickness and flow characteristics to allow effective cooling without excessive pump load.

Suitable for

• Custom water-cooling loops for CPUs and GPUs
• High-performance gaming and workstation builds requiring improved heat dissipation
• PC cases that support 420 mm radiators (three 120 mm fan positions)
• System upgrades where increased radiator surface area is needed

Key specifications

• Form factor: 420 mm radiator length suitable for three 120 mm fans
• Color: black finish
• Purpose: liquid-cooling radiator for PC cooling loops
• Mounting: compatible with 120 mm fan mounts and standard radiator mounting locations for 420 mm units
• Construction: multi-tube and fin assembly designed for thermal transfer and coolant flow

How to use

Install the radiator in a case or external mount location that supports 420 mm radiators, aligning it with three 120 mm fan positions. Attach appropriate fans and secure the radiator using the case or mounting hardware. Connect inlet and outlet ports to the rest of the water-cooling loop using suitable fittings and tubing, ensure correct flow direction, and fill the loop with compatible coolant following the coolant manufacturer’s instructions. After filling, perform leak testing and circulate the loop to remove air before normal operation.

Usage recommendations

Use high-quality compression fittings or barbed fittings compatible with the radiator ports and choose fans with appropriate airflow/static pressure for radiator use. Maintain regular coolant changes and system checks to prevent clogging and corrosion. Ensure case airflow supports radiator placement to maximize heat rejection efficiency.
