Stealkey Customs RadPro L420 H30 Radiator White (11432)

The SC RadPro L420 H30 White combines uncompromising cooling performance with a slim, modern design. Perfect for gamers, overclockers, and demanding workstation users who want to take their PC to the next level.

• Logo plug swap system
  On each side of the radiator there is a removable logo plate (logo plug). This allows the logo to be easily repositioned depending on the mounting orientation, ensuring correct alignment even in top-mount or bottom-mount installations.


• Compact dimensions
  With dimensions of 464 × 145 × 30 mm, the radiator remains extremely space-efficient despite its thickness ideal for cases that support 420 mm radiators.

High-quality material combination

The brass pre-chambers, in combination with the copper channels, ensure fast and even heat distribution and effectively reduce hotspots within the cooling loop.

All side and end rails are made of coated stainless steel, which not only provides reliable corrosion protection but also ensures a stable structure and a premium, uniform appearance.

Powerful and quiet across the entire RPM range of the RadPro L420

The optimized core structure delivers very good cooling performance even at low fan speeds. As RPM increases, performance scales almost linearly:

• Low RPM: Efficient cooling with minimal noise


• Medium RPM: Balanced ratio between noise level and temperature


• High RPM / Push-Pull: Maximum heat dissipation when up to six 140 mm fans are used in a push/pull configuration

Thanks to its low air and water resistance, the radiator does not put unnecessary strain on the pump or other components in the loop. Multiple SC RadPro radiators can easily be connected in series without overloading the pump (D5 or DDC).

Easy integration into any water-cooling loop

Two standardized G1/4 threads allow flexible and straightforward integration into the cooling loop without the need for special adapters.

The SC RadPro L420 H30 White is supplied with silver M4 screws and is compatible with all 140 mm fans. If longer screws are used accidentally, only the fins will be affected, not the fin core.

With a depth of just 145 mm, the radiator fits easily into all cases with standard 140 mm fan mounts, without requiring additional modifications.

Modular design for DIY modding enthusiasts

The SC RadPro L420 H30 White is designed as a modular system. Each component can be easily disassembled:

• Remove logo plates: Can be pulled off gently without tools.


• Detach side rails: Remove screws to access the copper core.


• Remove the core: Ideal for custom paint jobs, engravings, or expansions.

This allows you to customize your radiator freely and integrate it into any custom loop configuration.
