Liquid CPU Cooler THERMALTAKE MAGFloe 420 Black 420mm Radiator

THERMALTAKE MAGFloe 420 Black is a liquid CPU cooler with a 420 mm radiator designed to provide efficient thermal management for high-performance desktop processors. The cooler combines a 420mm radiator with an integrated pump and cold plate to improve heat transfer compared with typical air coolers. It is intended for systems where sustained low CPU temperatures are required, such as gaming rigs and workstation builds that run CPU-intensive tasks.

Advantages

The MAGFloe 420 Black delivers increased cooling capacity through a larger radiator surface area and multi-fan configuration, helping to lower CPU operating temperatures under load. Its liquid-cooling design reduces noise relative to many high-speed air coolers while maintaining steady thermal performance. The integrated cold plate and pump design provide continuous heat dissipation and are compatible with common CPU socket layouts used in modern consumer and professional motherboards.

Suitable for

• Gaming PCs with overclocked or high-TDP CPUs
• Workstations running rendering, simulation, or compilation workloads
• Compact to mid-tower cases that support a 420 mm radiator
• Users replacing stock air coolers for quieter sustained cooling

Key specifications

• Radiator length: 420 mm
• Cooling type: closed-loop liquid CPU cooler
• Configuration: multi-fan radiator mounting
• Compatibility: designed for modern desktop CPU sockets (check motherboard/case support before installation)
• Primary purpose: continuous heat transfer from CPU to radiator for active dissipation

How to use

Install the MAGFloe 420 Black by mounting the 420 mm radiator in a compatible case location and attaching the included fans as specified in the manual. Secure the pump/cold plate to the CPU socket following the provided mounting brackets and torque guidelines. Connect the pump power and fan headers to appropriate motherboard or controller headers and configure fan/pump curves in BIOS or software to match desired noise and performance levels. Verify clearance for RAM and other components prior to finalizing the installation.

Recommendations

For reliable results, ensure your case supports a 420 mm radiator and allows sufficient airflow through the radiator. Maintain periodic visual inspections of fan operation and radiator fins, and keep intake filters clean to preserve cooling efficiency. When configuring fan and pump speeds, balance between lower noise and required thermal headroom for your CPU workload.
