SUNON EF55151B1-Q010-S99 projector fan

This 12V 1.66W cooling fan is built for projector accessories that require a 4-wire 4-pin connection. It suits technicians or owners replacing a worn original unit with the same electrical interface. Buyers needing a different voltage, pin count or airflow profile should look elsewhere.

Sustained thermal behaviour

The fan runs continuously at its rated 12V 1.66W draw, delivering steady airflow for long projection sessions. Its 4-wire design allows speed reporting and control so the projector can regulate temperature without abrupt stops. No burst-speed claims are made beyond the stated power figure.

Pre-installation checks

Verify that your projector accepts a DC 12V 4-pin fan header and that the connector keying matches the EF55151B1-Q010-S99 layout. Confirm the mounting points align with the existing housing before ordering. Ensure the replacement does not exceed the chassis power budget allocated to the cooling subsystem.

Questions about this item

How much heat does the 1.66 W fan add when running continuously inside the projector?

The fan draws 1.66 W at 12 V, so its own heat contribution is very small compared with the lamp or laser module.

What voltage source and connector must the projector already provide for this 4-wire 4-pin fan?

The unit needs a 12 V DC supply and a matching 4-pin header on the projector's main board.

Will the EF55151B1-Q010-S99 fit the same mounting holes as the original SUNON cooler in my older projector?

The part number EF55151B1-Q010-S99 identifies the exact SUNON model; verify the projector's service manual lists this MPN before fitting.
