Fans BFB1212HH 5M2PR 12V 1.65A 4-pin 110mm 120x120x32mm blower case fan

SKU CH-YYVJ-2PXHG

12 V blower case fan with 4-pin PWM control, 120 × 120 × 32 mm frame and 1.65 A draw

  • High airflow from 120 mm square frame
  • Precise speed control via 4-pin PWM connector
  • Focused cooling with 110 mm blower impeller
  • Reliable 12 V DC operation at 1.65 A

110 mm blower fan for tight builds

This 120 mm square blower fits a 32 mm thick slot and draws 1.65 A at 12 V through a four-pin connector. The 110 mm impeller pushes air straight through the frame, making it suited for rackmount chassis, GPU shrouds or industrial enclosures where axial fans cannot exhaust directly. Buyers who need standard 120 mm side-intake cooling will not be served by this directional design.

Replaces worn Delta BFB1212HH units

The fan matches the original BFB1212HH 5M2PR form factor and electrical spec, so it drops into the same mounting holes and header without rewiring. Swapping is justified when the original develops bearing noise, speed-signal loss or reduced airflow under load. Systems that require variable-speed control via a different PWM curve or a lower current draw should look elsewhere.

Questions about this item

What are the exact mounting dimensions for the 120x120x32 mm blower frame?

The frame measures 120 mm by 120 mm square with a 32 mm thickness; mount it using the four corner holes on that 120 mm pitch.

Which wires connect to the 4-pin header for PWM control?

Plug the 4-pin connector directly onto the motherboard PWM header; the fourth wire carries the speed signal so the board can regulate the 12 V 1.65 A motor.
