Cooler Master MasterFan MF140 HALO² Case Fan (White)

The Cooler Master MFL-B4DW-16NP2-R2 is a 140 mm case fan from the MasterFan MF140 HALO² series, made for PC builders who want stronger airflow without turning their system into a noise machine. It drops easily into standard fan mounts and gives a gaming rig, workstation, or home office build the cooling headroom it needs to stay stable under load.

Cooling performance starts with blades that are ten percent larger than earlier versions. They spin up to 1600 RPM and move as much as 59.51 cubic feet of air per minute, yet the sound tops out at only 27 dBA. A rifle bearing limits friction for long life, and PWM support lets the motherboard handle fan speed automatically, so temperatures stay in check while noise remains low. The hybrid frame adds rigidity and keeps vibration from rattling your case.

Lighting is just as refined. Addressable RGB LEDs sit inside a center ring and an outer ring, and the frosted blades spread the light for a smooth glow that looks even from every angle. You can sync the fan with compatible motherboard software or use the included controller when an ARGB header is not available. Either way, color patterns and effects are easy to adjust on the fly.

Installation is straightforward. The fan ships with both 3 pin and 4 pin connectors, so it works with virtually any modern motherboard or fan hub. Use it as an intake that feeds cool air to a power hungry graphics card, mount it on a 280 mm radiator for liquid cooling, or place it at the rear of a mini tower that needs better exhaust.

Whether you are finishing a new build or refreshing an older system, the MasterFan MF140 HALO² delivers dependable airflow and customizable lighting in one clean package.
