Description
The Bitspower Leviathan II 420 (BPN-RL2422SL) represents a refined approach to liquid cooling thermal management. Measuring just 27mm in thickness, this slim-profile radiator is engineered for high-conductivity heat transfer using premium copper materials. The integration of single wave fins optimizes the surface area-to-airflow ratio, ensuring that even at lower fan speeds, the system maintains a stable thermal equilibrium for high-end components.
This product is for:
- Custom loop enthusiasts seeking a 420mm radiator that fits in cases with limited clearance above the motherboard.
- Silent PC builders who require high surface area to maintain low coolant temperatures with low-RPM 140mm fans.
- Professional workstation users needing reliable, long-term thermal stability for multi-GPU or high-TDP CPU setups.
- Aesthetic-focused modders looking for a clean, minimalist matte black finish that complements modern chassis designs.
- Performance-oriented gamers upgrading from standard AIOs to a bespoke open-loop system for better overclocking headroom.

Installing the Leviathan II 420 is straightforward due to its standardized G1/4" porting and precise screw alignment. In operation, the copper construction facilitates rapid heat soak from the coolant into the fins. When paired with high-static pressure 140mm fans, the single wave fin geometry reduces air resistance, allowing for efficient heat exhaustion without the turbulence noise often associated with denser, thicker radiators.
Compared to the original Leviathan series, the Leviathan II 420 optimizes the fin density to better balance airflow and thermal capacity. While thicker 45mm or 60mm radiators offer more mass, they often require push-pull fan configurations to be effective; the Leviathan II's 27mm slim design achieves comparable real-world performance in standard pull or push setups, making it more versatile for mid-to-full tower cases.
Q&A:
- Does the Bitspower Leviathan II 420 include fans? No, fans must be purchased separately to match your specific airflow and aesthetic requirements.
- What is the benefit of copper over aluminum in this radiator? Copper has significantly higher thermal conductivity, allowing for faster heat transfer and preventing galvanic corrosion when used with other copper or brass components.
- Will this radiator fit in a standard ATX case? It requires a mounting location that supports a 420mm length (3x140mm); check your chassis specifications for 420mm radiator support.
- What size fittings should I use? The radiator features standard G1/4" threads, making it compatible with the vast majority of compression and barb fittings on the market.
- Is the 27mm thickness sufficient for high-end CPUs? Yes, the large 420mm surface area compensates for the slim profile, providing ample cooling capacity for modern high-TDP processors.
