Frequently Asked Questions

What is SUNON GM1202PFB3-8?
GM1202PFB3-8 is a SUNON miniature DC axial cooling fan. Exact-model commercial references identify a 12 VDC supply, 0.5 W power consumption, nominal 25 x 25 x 10 mm dimensions and two-wire connection.

What is the rated voltage of GM1202PFB3-8?
Commercial exact-model references specify 12 VDC. The manufacturer's allowable operating voltage range and minimum starting voltage were not independently verified for GM1202PFB3-8.

What are the dimensions of GM1202PFB3-8?
The nominal dimensions are 25 x 25 x 10 mm, as specified by an electronic components distributor listing the complete GM1202PFB3-8 model. Exact mounting-hole center spacing and mechanical tolerances were not independently verified.

What is the rated current?
A standalone manufacturer current rating for GM1202PFB3-8 was not located. The published 0.5 W power rating divided by 12 VDC gives an estimated operating current of approximately 41.7 mA. This calculated figure is not a confirmed maximum or manufacturer-rated current.

What is the power consumption?
The exact model is listed at 0.5 W by multiple commercial suppliers. The value also appears in product descriptions showing the complete GM1202PFB3-8 part number.

What is the rated fan speed?
A verified SUNON RPM specification for GM1202PFB3-8 was not located. The similarly named KDE1202PFB3-8 is rated at 7000 RPM in the traditional motor catalog, while GM1202PFV2-8.GN is rated at 10000 RPM in the MagLev catalog. Neither rating should automatically be assigned to GM1202PFB3-8.

What airflow does GM1202PFB3-8 provide?
An independently verified airflow specification for this exact model was not located. For comparison only, the separate KDE1202PFB3-8 model is listed at 1.3 CFM, while GM1202PFV2-8.GN is listed at 3.0 CFM. These are not confirmed GM1202PFB3-8 ratings.

What is the maximum static pressure?
An exact-model static pressure rating was not independently verified. Values from other 25 mm SUNON GM or KDE configurations should not be used for engineering calculations unless the manufacturer confirms they apply to GM1202PFB3-8.

What bearing system does GM1202PFB3-8 use?
The PFB designation is associated with ball-bearing versions in SUNON fan naming conventions, but a complete GM1202PFB3-8 manufacturer datasheet confirming the exact bearing arrangement was not located. Verify the bearing type before ordering if it is important for the replacement application.

What is the acoustical noise level?
No independently verified manufacturer noise rating was located for the complete GM1202PFB3-8 model. Related KDE1202PFB3-8 and GM1202PFV-series fans have different published acoustic characteristics, so their noise figures should not be transferred to this fan.

How is GM1202PFB3-8 electrically connected?
The exact model is listed with two DC power leads, and some commercial replacement listings describe a two-pin connector. The precise connector pitch, lead length and wire polarity were not independently verified. Match the existing fan connector and confirm polarity before connecting the fan to a 12 VDC supply. No dedicated third-wire tachometer or fourth-wire PWM input is present in the documented two-wire configuration.

What should be checked before ordering GM1202PFB3-8?
Confirm the complete SUNON GM1202PFB3-8 model designation, 12 VDC supply, 0.5 W listed power consumption, nominal 25 x 25 x 10 mm housing, bearing construction, mounting geometry, two-wire termination, connector orientation and required airflow direction. If replacing another model, verify rated speed, airflow, static pressure and noise against the equipment requirements. KDE1202PFB3-8, GM1202PFV1-8.GN and GM1202PFV2-8.GN have their own separate published specifications and should not automatically be treated as interchangeable. Obtain the specific product technical drawing or compare the actual nameplate and installed assembly whenever exact compatibility is required.
