Cooling fan for BenQ Optoma Nut S1 Honghe H71W

This 12 V DC cooling fan is designed as a direct replacement for the SUNON GM1255PHV1-A model used in specific BenQ, Optoma, Nut and Honghe projectors. It operates at 1.7 W and fits the exact mounting footprint required by those devices. The unit is supplied new and ready for installation.

Three-wire three-pin connector enables speed

The 3-wire 3-pin interface provides power, ground and a tachometer signal so the projector can monitor fan speed. This allows the system to detect a stalled or failing fan and trigger protective shutdowns. The connector matches the original equipment layout without adapters.

Verify the 55 mm by 15 mm frame

Check that your projector uses a 55 mm by 15 mm frame fan rated for 12 V DC and 1.7 W. Confirm the existing fan carries the GM1255PHV1-A or 5515 part number. This fan is not suitable for models requiring a different voltage, frame size or pin configuration.

Questions about this item

How often should the SUNON GM1255PHV1-A fan be cleaned or replaced in a BenQ Optoma Nut S1 Honghe H71W projector?

Clean the 55mm x 15mm fan every six months with compressed air to remove dust buildup. Replace the unit if bearing noise appears or airflow drops below the 1.7W design point.

What is the first limit reached when the GM1255PHV1-A runs continuously at 12V?

The 1.7W power ceiling is the first sustained-use limit; exceeding it stresses the 3-wire 3-pin motor and reduces bearing life.

How much noise and heat does the 5515 fan produce during all-day operation?

At 12V the fan runs near its rated 1.7W, so audible airflow noise is moderate and exhaust air feels warm but not hot to the touch.
