Frequently Asked Questions

What is SUNON PFC0251BX-C010-S99?
PFC0251BX-C010-S99 is a SUNON DC brushless centrifugal cooling blower commonly used in compatible Dell OptiPlex Small Form Factor CPU cooling assemblies.

What is the rated voltage of PFC0251BX-C010-S99?
The exact-model fan marking and multiple replacement listings identify a rated supply of 12 VDC.

What is the power consumption?
SUNON PFC0251BX-C010-S99 is listed at 6.84 W. This rating is also reported in a Dell owner discussion identifying the installed CPU fan model.

What is the rated current?
The documented current is 0.57 A at 12 VDC, consistent with the 6.84 W power marking.

Is PFC0251BX-C010-S99 an axial fan or a centrifugal blower?
It is a centrifugal blower with a shrouded housing and directed air outlet. It is not a conventional square-frame axial fan.

What are the dimensions of PFC0251BX-C010-S99?
A dimensioned manufacturer drawing for the complete cooling blower was not independently located. Because the housing and mounting bracket are equipment-specific, compare the existing assembly rather than relying on generic 100 mm or 120 mm retail fan classifications.

What airflow does PFC0251BX-C010-S99 provide?
A specialist replacement supplier reports a minimum airflow value of 23.8 CFM, approximately 40.4 m³/h. This is supplier-reported information; an exact-model manufacturer airflow curve was not independently established.

What is the rated fan speed?
An exact manufacturer RPM rating has not been independently verified. Some unrelated retail listings publish different speed figures, which should not be used for engineering selection without checking the complete fan configuration.

What bearing system does PFC0251BX-C010-S99 use?
A specialist computer replacement-parts supplier lists a ball bearing system. An exact-model SUNON bearing specification was not independently located.

How many wires and connector pins does the fan have?
The commonly documented assembly has four electrical wires. Some suppliers describe a four-pin connection, while others specify four wires terminating in a five-position Dell-style connector. Verify the connector housing, populated positions, wiring order and signal pinout against the existing fan.

Which Dell computers use PFC0251BX-C010-S99?
Replacement suppliers commonly identify Dell OptiPlex 390, 790 and 990 Small Form Factor systems. Some also list selected OptiPlex 3010, 7010 and 9010 SFF configurations. These references do not establish universal compatibility across every configuration of those computers; check Dell part number 0J50GH and the existing cooler assembly.

What should be checked before ordering PFC0251BX-C010-S99?
Confirm the complete SUNON PFC0251BX-C010-S99 model number, 12 VDC supply, 0.57 A rated current, 6.84 W power rating, Dell part reference, blower housing dimensions, bracket and mounting arrangement, connector housing, four-wire pinout, airflow direction and exact desktop configuration. Also verify whether the required replacement is the bare blower, a blower with a mounting bracket or a complete CPU heatsink assembly. Related fans and cooling assemblies should not be substituted solely because they fit the same Dell computer family.
