Compact 45mm Blower for Projector Cooling

The Zyvpee GB1245PKV1-8AY is a 12V blower fan built for tight projector housings. Its 45 by 20 millimetre frame targets repair technicians and integrators who need a direct replacement for original cooling modules. The three-wire connector supports speed monitoring on compatible controller boards.

Drop-in Installation with Ball Bearing Reliability

The three-pin plug matches the standard header found on many projector mainboards, so no soldering or adapter cables are required. A ball bearing keeps noise predictable over long duty cycles, but the sub-1600 RPM ceiling limits airflow in heavily restricted ducts. Verify the mounting screw pattern before ordering, as hole spacing varies between projector brands.

12V 0.5W Power Envelope Decides Fit

The fan draws 0.5 watt at 12 volts, a figure that must match the projector’s onboard fan header rating. Exceeding the header’s current budget can trigger protection shutdowns or damage the driver IC. Buyers who need higher static pressure or a different voltage rail should look elsewhere.

Questions about this item

How do I confirm the blower fan is running correctly after installation?

The fan should spin below 1600 RPM at 12 V and draw 0.5 W; a steady airflow from the 45 mm housing indicates normal operation.

What comes in the box and what must I source separately?

The package includes the 45×20 mm blower with 3‑pin connector; mounting screws, power adapter or PWM controller are not included.

Which version of the GB1245PKV1-8AY should I choose for my projector?

This model is the 12 V, 0.5 W, 3‑wire ball‑bearing variant (11.F.X.GN); select it only if your projector requires those exact specifications.
