SKU CH-91PF-K3P19

12 V PWM case fan with dual ball bearings and four-wire speed control

  • 12 V operation powers the fan directly from standard PSU rails
  • 8 A draw keeps current load low on the 12 V line
  • 4-wire PWM control enables precise speed regulation
  • Dual ball bearing design extends operating life

Delta AFB1212SH 12V PWM case fan

The Delta AFB1212SH is a 12 V case fan built with dual ball bearings and a four-wire PWM interface for precise speed control. It suits system builders who need reliable airflow in servers or workstations. The .8 A current draw keeps power use predictable. Buyers who want a larger diameter or lower voltage model should look elsewhere.

Thermals noise and power draw

Dual ball bearings provide consistent rotation with minimal wobble over long operating periods. PWM control allows the fan to run quietly at low speeds and ramp up only when thermal load demands it. At 12 V the unit draws .8 A, giving a steady power profile for chassis thermal planning. No additional controller is required beyond a standard motherboard header.

Questions about this item

How do I connect the 4-wire PWM connector on the AFB1212SH to my motherboard header?

Align the keyed 4-pin plug with the motherboard's PWM header so the missing pin matches the blocked hole; pressing it straight in seats all four contacts.

Will the dual ball bearing in the AFB1212SH need lubrication or replacement after extended use?

Dual ball bearings are sealed for life and do not require lubrication; they typically last tens of thousands of hours before any bearing-related service is considered.
