CPU air cooler FSP NP5-B, 120 mm fan, HDB bearing, supports LGA1200/LGA1700/AM4/AM5, black
FSP NP5-B is a compact 120 mm air CPU cooler designed for standard desktop and gaming systems. It combines an aluminum alloy heatsink, a 120 mm Hydro Dynamic Bearing (HDB) PWM fan and a low-profile form factor (94 × 120 × 151 mm) to provide effective heat dissipation while maintaining full RAM clearance. The cooler supports modern CPU sockets including LGA1200, LGA1700, AM4 and AM5 and comes in a black finish that integrates with most black PC builds.
The NP5-B uses an aluminum alloy design to ensure efficient thermal conductivity and fast heat transfer from the CPU. Its 120 mm HDB fan operates across a controlled RPM range to balance cooling performance and acoustic comfort, and anti-vibration rubber pads reduce vibration noise. The compact dimensions and full RAM clearance make the cooler suitable for most mid-tower cases, while the black coating provides a uniform appearance in black-themed systems. The mounting bracket is designed for straightforward installation on supported sockets.
Prepare the motherboard and CPU socket according to the motherboard manufacturer’s instructions. Position the NP5-B cooler so the base makes direct contact with the CPU integrated heatspreader, apply an appropriate amount of thermal paste if not pre-applied, and secure the cooler using the supplied mounting bracket and fasteners for the target socket. Connect the 4-pin PWM fan header to the motherboard CPU fan connector to enable speed control. Ensure the cooler is installed vertically as intended for optimal heat pipe performance and check clearances for RAM and surrounding components before powering the system.
For best results, use a high-quality thermal paste and verify that the fan header in BIOS/UEFI is configured for PWM control to allow automatic fan speed adjustment. Regularly inspect and clean dust from the heatsink fins and fan to maintain airflow. When installing in compact cases, confirm the 151 mm height fits your chassis and that airflow direction aligns with your case fans for efficient exhaust.
