12V 4PIN 120mm System Fan Assembly

This new internal power cable assembly is a 12V 120mm system fan with a 4PIN power interface. It fits server models 6600 and 6650 as a hot-swap replacement. The unit is built by NMB under part number 3F186 and ships in its original package.

Sustained airflow at 1500 to 2000 RPM

The fan spins between 1500 and 2000 RPM to maintain steady airflow under continuous server load. Seven blades move air through the chassis without the speed spikes seen in shorter bursts. Rated life reaches 100000 hours of operation.

Hot-swap limit in 4PIN server bays

The 4PIN connector allows removal while the server runs, but only in bays designed for hot-swap insertion. Standard 4PIN headers without hot-swap circuitry will not support live replacement. Buyers needing a non-hot-swap case fan should choose a different assembly.

Questions about this item

How loud and hot does the 12V 4PIN fan run at 1500-2000 rpm continuously?

The 12V 4PIN fan spins between 1500 and 2000 rpm with seven blades, moving air through a 120 mm frame; power draw stays at 12V and the rated life is 100000 hours.

What motherboard header or controller must I already have for the 4PIN connector?

A standard 4-pin PWM header on the motherboard or a 4-pin fan controller supplies the 12V signal the cable expects.

Will the 3N541 120mm assembly fit the mounting holes of my older 6600 or 6650 server chassis?

The 3N541 model matches the 6600 and 6650 hot-swap form factor, so it aligns with the original 120 mm mounting pattern used in those servers.
