Compact 12V server fan

The 1910RL-04W-B49 X01 is a 12V DC case fan drawing 0.21A. Its 47x47x25mm frame fits tight server and workstation chassis where space is limited. The three-wire connection provides tachometer feedback for system monitoring.

Three-wire tachometer included

The 3-wire lead supplies a speed signal so the motherboard or fan controller can track rotation. No PWM wire is present, so voltage control is the only speed-regulation method. Buyers needing 4-pin PWM control or larger airflow volumes should look elsewhere.

Questions about this item

When will the 3-wire connector need replacement?

The 3-wire connector is rated for repeated mating cycles; replace it if the pins loosen or the latch breaks during a fan swap.

What limit appears first when the fan runs continuously at 12 V?

Continuous 12 V operation draws 0.21 A; the motor's thermal limit is reached before the supply voltage sags.
