Cooler Master MasterFan MF140 HALO² Case Fan (Black)

The Cooler Master MFL-B4DN-16NP2-R2 is a 140 mm case fan that blends dependable cooling with addressable RGB lighting you can tailor to any build. It drops straight into a gaming rig, a creator workstation, or even a quiet home-office PC, adding both performance and color without extra fuss.

Dual loop LEDs surround the hub and rim, producing an even glow that syncs with popular motherboard lighting software. You can match system themes, call out key components, or simply enjoy a shifting light show while you work or play.

Cooling power comes from enlarged Air Balance blades that move up to 59.51 CFM at 1600 RPM. A hybrid frame keeps the fan rigid, guiding airflow toward hot spots and minimizing vibration. Even at full speed the fan tops out at 27 dBA, so your game audio or conference call stays clear.

PWM control lets the motherboard adjust fan speed from a silent zero-RPM idle up to maximum airflow under load. This flexibility means you can keep noise down during routine tasks, then ramp up cooling for extended gaming sessions, 3D rendering, or summer heatwaves.

Inside the hub, a rifle bearing rated for more than 160 000 hours provides long-term reliability. That durability makes the fan a smart pick for builders who want to set up a system once and enjoy it for years. With standard 4-pin PWM and 3-pin ARGB connectors, installation is quick in most modern cases and on common fan hubs.

Whether you are refreshing an older chassis or finishing a new build, the MasterFan MF140 HALO² adds the airflow and visual polish that turn a PC into something personal.
