High-speed 120mm case fan
The Manw FFC1212DE is a 120mm by 38mm dual ball bearing fan built for systems that demand extreme airflow. It connects via a standard 3-pin connector with a speed sensor and includes a metal finger guard plus mounting hardware. This unit targets server chassis, high-density workstations or any enclosure where moving maximum air volume takes priority over silence.
200 CFM airflow at 4000 RPM
At full speed the fan delivers 200 CFM, providing substantial headroom for multi-core CPUs, multi-GPU arrays or densely packed storage bays. The 36W motor draws 3.0A on 12V DC, so the header or fan controller must supply that current without throttling. In less restrictive layouts the raw output can exceed what the heatsink or chassis impedance can absorb, so diminishing returns appear once static pressure saturates the flow path.
59 dBA noise level and 36W power draw
Normal operation sits at 59 dBA, a level clearly audible in quiet rooms and unsuitable for living-space desktops. The 28cm cable reaches most motherboard headers but may require an extension in full-tower or rear-mounted server builds. Dual ball bearings support long life under continuous 4000 RPM duty cycles, though the 400g mass demands secure fastening to prevent vibration transfer to the chassis.

Questions about this item
Will the 4000 RPM 3-pin connector work on my older motherboard that only has 3-pin headers?
Yes, the 3-pin connector fits standard 3-pin headers and the motherboard will control speed by varying voltage.
How can I confirm the fan is spinning at the rated 4000 RPM after installation?
Connect the third wire to a motherboard header or fan controller that reads the speed sensor, then monitor RPM in BIOS or hardware-monitoring software.
Does the package include the metal finger guard grill and mounting hardware, or do I buy them separately?
The box contains the fan, one metal finger guard grill, and four screws with nuts for mounting.
