Compact 45 mm blower for tight builds

The Zyvpee BSB04505HA is a 45 mm square DC blower measuring 45 by 6 mm. It runs on 5 V at 0.30 A through a 4-pin connector and uses a ball bearing. The non-LED black frame targets notebook, laptop, switch or small-form-factor CPU cooling where space is at a premium.

Replaces worn 45 mm 4-pin blowers

This unit fits the same 4506 footprint as many original-equipment fans in compact devices. The jump is worth it when the original sleeve-bearing fan becomes noisy or fails, because the ball bearing offers longer life at the same voltage and pin-out. No larger frame or different voltage is required.

Suits repairers and modders with 45 mm bays

Builders who need a drop-in 5 V 4-pin blower for a 45 mm square cut-out will find it compatible. Buyers who want more airflow than a 45 mm blower can deliver, or who need PWM speed reporting on a 3-pin header, should look at something else.

Questions about this item

Will the 45 mm by 6 mm frame and 4-pin connector fit my laptop's fan header?

The fan measures 45 mm square by 6 mm thick and uses a 4-pin power connector, so it matches headers with that exact footprint and pin count.

How do I install the blower and which orientation step is often missed?

Align the 4-pin plug with the motherboard header, secure the 45 mm frame with the original screws, and ensure the airflow arrow points toward the heatsink — reversing it is the common error.

When will the ball bearing need replacement and what indicates wear?

The ball bearing is rated for long life; plan to replace the fan if you hear new grinding noise or feel vibration that cleaning does not remove.
