Projector Cooling Fan Replacement

This 92 mm square fan is designed to replace the Sunon MF92251V3-Q020-Q99 unit in projector housings. It runs on 12 V DC and draws 1.74 W through a four-wire PWM interface. The two ball bearing assembly targets a 70000 hour service life. Buyers who need a different voltage or mounting pattern should look elsewhere.

Sustained Load Behaviour

The motor spins up to 18000 RPM with a tolerance of ten percent across the 7.0 to 13.4 V operating range. PWM intelligent temperature control adjusts speed automatically as internal temperatures rise. Airflow reaches 19.4 CFM to maintain steady heat removal during long projection sessions. The plastic frame and impeller keep rotational mass low for quick response.

Thermals Noise and Power

At full speed the fan produces 54 dB of radiator noise, which is audible in quiet rooms. Power consumption stays at the rated 1.74 W under normal projector loads. The four-line connection supplies power, ground, PWM control and tachometer feedback for monitoring. No additional heatsink material or ducting is included in the package.

Questions about this item

How loud is the 54 dB noise rating when this 12 V fan runs continuously?

The fan produces 54 dB of radiator noise at full speed, which is audible in a quiet room but typical for a high-RPM 40 mm cooler.

Does the 4-pin PWM connector plug straight into a standard motherboard header?

Yes, the 4-wire interface uses a standard 4-pin PWM plug that fits common motherboard fan headers for speed control and monitoring.

Will the 40×40×28 mm frame and 4-pin PWM control work in a legacy chassis with only 3-pin headers?

The 4-pin connector is backward-compatible with 3-pin headers; the fan will run at full 18000 RPM without PWM speed regulation.
