Tripp Lite In-Line Network Surge Protector, 10 Gbps, Cat6a/8, Metal Case, IEC Compliant, TAA

The Cooler Master MFX-B2NN-18NPK-R1 is a 120 mm PWM fan designed to move air efficiently through a computer case or across a liquid-cooling radiator. An updated blade shape generates higher air pressure and improves flow, reaching up to 62 CFM when the system demands full cooling. A sealed rifle bearing keeps dust and oil away from critical parts, so the fan stays stable and operates within a noise range of 8 to 27 dBA.

This model fits builders who need balanced performance and quiet operation. A gaming tower with a power-hungry CPU and graphics card can use the fan as an intake or exhaust to keep temperatures under control during long sessions. A workstation in a shared office can run the fan at its lower speeds, where the noise falls to a level that blends into normal background sound. Liquid-cooling enthusiasts can mount several of these fans on a 360 mm radiator, trusting the 4-pin PWM connector to modulate speeds from 650 to 1800 RPM in response to real-time temperature readings. The all-black finish complements RGB lighting, stealth builds, or any setup that calls for a clean appearance.

Installation is straightforward because the frame matches the standard 120 mm mounting pattern found on most cases and radiators. The fan draws only 2.64 W, keeping overall system power use in check, and its reinforced structure reduces turbulence for smoother airflow. Whether you are refreshing an older rig or completing a new build, this fan offers a practical way to improve cooling while maintaining a refined look.
