Frequently Asked Questions

What is SUNON MF75251V1-Q020-G99?
MF75251V1-Q020-G99 is a SUNON DC brushless axial cooling fan commercially listed for projector and compact electronic equipment cooling. Exact-model suppliers identify a nominal 12 VDC supply and 3.60 W power rating.

What is the rated voltage of MF75251V1-Q020-G99?
Multiple replacement-part suppliers specify 12 VDC. An independently verified manufacturer operating voltage range for this exact configuration was not located.

What are the dimensions of MF75251V1-Q020-G99?
Most exact-model listings specify 75 x 75 x 25 mm. One industrial spare-parts supplier identifies 70 x 70 x 25 mm, while another supplier categorizes the fan as approximately 77 x 77 x 25 mm. Confirm measurements and mounting-hole positions against the existing fan before ordering.

What is the power consumption?
Multiple commercial listings for the complete MF75251V1-Q020-G99 model identify 3.60 W at 12 VDC.

What is the rated current?
Dividing the listed 3.60 W power by 12 VDC gives a calculated current of approximately 0.30 A. This is a mathematical estimate rather than a separately verified manufacturer current specification.

What is the rated fan speed?
A reliable exact-model RPM specification was not independently verified. Do not substitute the speed value of another SUNON MF-series fan without checking its complete model number and configuration.

What airflow does MF75251V1-Q020-G99 provide?
An exact-model manufacturer airflow rating in CFM or m³/h was not independently established. The required cooling performance should be confirmed using the equipment specification or an applicable manufacturer datasheet.

What is the static pressure rating?
An independently verified maximum static pressure rating for the complete Q020-G99 configuration was not located. This value should not be estimated from frame dimensions or from a different SUNON fan model.

What bearing system does MF75251V1-Q020-G99 use?
The bearing construction of the exact Q020-G99 configuration has not been independently verified. Although SUNON produces MagLev and Vapo bearing fans, their specifications should not automatically be assigned to this model.

What is the acoustical noise level?
A manufacturer noise rating for MF75251V1-Q020-G99 was not independently located. Actual operating noise also depends on fan speed, airflow restrictions and the equipment enclosure.

How is MF75251V1-Q020-G99 electrically connected?
The commonly listed replacement assembly uses three wire leads with a three-pin connector. Some sellers offer alternative two-wire or four-wire assemblies. Confirm the connector type, cable length, polarity and third-wire signal before installation rather than assuming all versions use the same pinout.

What should be checked before ordering MF75251V1-Q020-G99?
Confirm the complete SUNON model number, 12 VDC supply, 3.60 W power rating, physical dimensions, mounting-hole spacing, fan thickness, three-pin connection, cable length, wire polarity, airflow direction and projector or equipment compatibility. Because suppliers report different external dimensions and the exact manufacturer performance datasheet has not been established, comparing the existing fan label, photographs and measured mounting geometry is especially important. Do not automatically substitute MF75251V1 models with different suffixes or connector arrangements.
