Fans BS401012M 12V 0.09A North Bridge Mute Speed Measurement case fan

SKU CH-6Z45-CE5P3

A 12 V case fan drawing 0.09 A with speed measurement for quiet north-bridge cooling

  • Operates at 12 V for standard PC power delivery
  • Draws only 0.09 A to minimise current load
  • Mute design reduces audible noise during operation
  • Speed measurement support enables RPM monitoring

Compact 12V case fan

The BS401012M is a 12 V case fan rated at 0.09 A for targeted airflow in tight spaces. It suits builders who need a low-draw cooler for north-bridge heatsinks or similar small-form-factor zones.

Simple two-wire installation

Connection uses standard two-pin power so it fits most headers without adapters. The mute design keeps acoustic output low, but the fixed speed means it cannot ramp under heavy loads. Buyers who need PWM control or higher static pressure should look elsewhere.
