  • 12 V operation powers demanding server chassis
  • Four-wire design enables precise PWM speed control
  • 120 × 120 × 38 mm frame fits standard 120 mm mounts
  • 48 A draw balances airflow with energy efficiency

LORDWORLD 120 mm 4-wire server fan

The LORDWORLD 109R1212MH1031 is a 120 mm square cooling fan built for server chassis and similar enclosures. It runs on 12 V power and draws 0.48 A through a four-wire connection that supports speed monitoring and control. The frame measures 120 by 120 by 38 mm and the unit is supplied new.

Limits of 12 V four-wire fan control

The fan requires a 12 V header capable of delivering at least 0.48 A and a PWM or voltage-control signal on the fourth wire for regulated speed. Builders whose boards only offer three-pin headers will lose automatic speed management. The 38 mm thickness may not fit in shallow rack units or slim cases, and the current draw rules out low-power fan controllers rated below 0.48 A.

Questions about this item

Should I pick the 120 mm by 38 mm four-wire version or a thinner two-wire model for my server chassis?

Choose the 120 mm by 38 mm four-wire model when your chassis mounts 38 mm thick fans and the motherboard or fan controller provides a 12 V four-pin header; the extra wire adds PWM speed control and tachometer feedback that two-wire fans lack.

What does the 0.48 A current draw mean once the fan is installed in a 12 V system?

At 12 V the fan draws 0.48 A, so the 12 V rail must be able to deliver that current continuously; a typical 4-pin header rated for 1 A or more will power the fan without voltage droop.
