Compact blower for tight spaces

This 50 mm by 25 mm blower moves air through a focused outlet, making it suited to small-form-factor chassis or rack units where a traditional top-down cooler cannot fit. The three-wire connection provides tachometer feedback so the system can monitor fan speed. It runs on 12 V power and draws 0.15 A.

Steady airflow at constant voltage

Because the motor is rated for continuous 12 V operation at 0.15 A, the blower maintains a consistent flow rate during prolonged workloads without the current spikes seen in some PWM designs. The fixed-speed characteristic means acoustic output stays stable once the chassis reaches thermal equilibrium.

Check mounting pattern and header type

Verify that your motherboard or controller board offers a three-pin 12 V fan header and that the 50 mm square mounting holes align with the cooler bracket or heatsink base you intend to use. The blower-only design requires a separate heatsink or duct to direct air over the CPU die.

Questions about this item

How much power does the 12 V 0.15 A blower draw when running continuously?

The blower is rated at 12 V and 0.15 A, so it draws very little power even during all-day operation.

What connector does the 3-wire blower need on the motherboard or controller?

It uses a standard 3-wire fan header for power and tachometer signal.

Will the 50 mm blower fit in the same mounting holes as my existing 5025-size cooler?

Yes, the 50×25 mm frame matches the 5025 form factor used by many legacy coolers.
