FSP NP5-B | 120mm PWM | 4x Heat-pipes | Universal Socket

Overview

The FSP NP5-B CPU air cooler is a masterclass in thermal engineering, designed to provide consistent, reliable cooling for a wide range of modern processors. By effectively dissipating heat through a high-quality aluminum alloy heatsink and four precision-engineered 6mm heat pipes, it ensures your CPU maintains optimal operating temperatures even during intensive workloads. This cooler is an essential upgrade for any PC builder looking to eliminate thermal throttling and protect their hardware investment.

Equipped with a responsive 120mm PWM fan, the NP5-B dynamically adjusts its cooling output based on real-time temperature demands. This intelligent regulation allows the system to remain whisper-quiet during light tasks while ramping up to 1600 RPM when the pressure is on. With its robust HDB bearing construction and broad socket support, it is built to provide years of dependable service in both gaming rigs and professional workstations.

Key Features & Benefits

• Dynamic PWM Cooling: Automatically modulates fan speed between 800 and 1600 RPM to balance acoustic comfort with cooling power.
• Advanced Heat Transfer: Utilises four 6mm copper-contact heat pipes to rapidly move heat away from the CPU die into the fin array.
• Universal Socket Compatibility: Engineered for seamless installation across Intel LGA 1851, 1700, 1200 and AMD AM4, AM5 platforms.
• Silent Operation: Operates at a maximum noise level of just 28 dBA, ensuring your focus remains on your game or creative project.
• Reliable HDB Bearing: High-durability bearing technology extends the lifespan of the fan, providing consistent performance over extended usage cycles.

Performance & Best Use Cases

The FSP NP5-B is designed to thrive in environments where thermal efficiency and noise control are paramount. Whether you are assembling a new mid-range gaming PC or upgrading an existing workstation, this cooler provides the necessary headroom to keep your CPU stable under load.

• Best For: Mid-tower gaming builds and home office workstations.
• Use Case: Maintaining cool temperatures during long gaming sessions or heavy multitasking.
• Practical Advantage: The compact 15.1cm height ensures compatibility with the vast majority of standard ATX chassis.
• Why Choose It: It offers a premium balance of build quality, quiet acoustics, and broad compatibility at an accessible price point.

Connectivity, Cooling & Power

The FSP NP5-B connects via a standard 4-pin PWM header, allowing your motherboard to take full control of the fan curve. With a rated voltage of 12 VDC and a low power draw of 0.3 A, it is highly efficient and compatible with virtually any modern power supply and motherboard configuration. The integration of the HDB bearing fan ensures that the airflow of 62 CFM is delivered consistently without the mechanical degradation found in cheaper sleeve-bearing alternatives.
