TOPLAB

TOPLAB 9BMB12P2K01 12V 3.4A 97x97x33mm 4-wire Server Blower Fan

SKU CH-3MK2-MX3GT

A 97 mm square, 33 mm thick 12 V blower fan drawing 3.4 A with four-wire PWM control for server cooling

  • 12 V DC input for server-grade power delivery
  • 4 A current rating supports high airflow demand
  • 97 mm square frame fits standard 1U blower slots
  • 4-wire PWM control enables precise speed regulation

12V 3.4A Server Blower Fan

The TOPLAB 9BMB12P2K01 is a 12V DC blower fan rated at 3.4A for server and industrial chassis. Its 97x97x33mm frame fits standard 1U and 2U rack mounts where directed airflow must cross dense component stacks. The four-wire PWM interface allows the host system to modulate speed based on thermal load.

4-wire PWM upgrade for legacy 3-wire units

Replaces older 3-wire blowers that run at fixed speed regardless of temperature. The jump is worth it when the platform supports PWM control and the chassis clearance matches the 33mm depth, enabling quieter idle operation and tighter thermal margins under load. Not suited for builds requiring a larger frame or lower current draw.

Highlights

  • 12 V DC input for server-grade power delivery
  • 4 A current rating supports high airflow demand
  • 97 mm square frame fits standard 1U blower slots
  • 4-wire PWM control enables precise speed regulation

Questions about this item

What are the mounting hole dimensions for the 97x97mm blower fan?

The fan measures 97mm by 97mm with a 33mm thickness, so mounting holes will match that square footprint.

How do I connect the 4-wire PWM lead on the 12V 3.4A server blower?

Plug the 4-pin connector into a 12V PWM header; the fourth wire carries the speed-control signal while the other three handle power and ground.
