  • Compact 45 × 45 × 20 mm footprint fits tight server chassis
  • 12 V, 0.24 A draw keeps power budget low
  • 3-wire connection enables speed monitoring and control
  • Blower design pushes air through restricted inverter paths

Compact 45 mm Blower Fan

Two 45×45×20 mm blower fans operate at 12 V and draw 0.24 A each. The 3-wire connection provides power and speed reporting. Their square frame and focused airflow suit tight server or inverter enclosures. Sold as a new pair for immediate installation.

Builders needing focused airflow in 45 mm slots

Technicians who require PWM speed control cannot use these fans. Buyers needing larger frame sizes or higher static pressure must select different models. The 3-wire interface limits automatic curve adjustment.

Questions about this item

What sustained-load limit appears first with the 12 V 0.24 A blower?

The 0.24 A current draw at 12 V sets the thermal ceiling; prolonged operation at full speed will hit the motor's rated power limit before airflow drops.

How much noise and heat does the 45×45×20 mm blower produce in 24/7 server use?

The 3-wire 12 V 0.24 A motor runs continuously within its rated envelope, generating only the airflow noise and waste heat inherent to that power level.
