Frequently Asked Questions

What is SUNON EE80251S1-D170-F99?
EE80251S1-D170-F99 is a SUNON EE-series DC brushless axial cooling fan featuring a nominal 80 x 80 x 25 mm housing, 12 VDC supply and a three-wire electrical connection.

What is the rated voltage of EE80251S1-D170-F99?
Multiple exact-model commercial listings specify 12 VDC. A supplier reports an operating voltage range of 4.5-13.8 VDC, but this range has not been independently confirmed in an exact D170-F99 manufacturer datasheet.

What are the dimensions of EE80251S1-D170-F99?
The nominal dimensions are 80 x 80 x 25 mm. The related SUNON EE8025 series drawing specifies 71.5 mm mounting-hole center spacing and 4.3 mm mounting holes. Confirm the actual assembly dimensions and cable exit position before installation.

What is the rated current?
An exact-model supplier lists 0.14 A. SUNON's related EE80251S1-0000-A99 catalog model is rated at 0.145 A. Because these have different customer and function suffixes, the complete D170-F99 electrical rating should be confirmed against the supplied fan label.

What is the power consumption?
Multiple replacement-part listings specify 1.7 W at 12 VDC for the complete EE80251S1-D170-F99 model.

What is the rated fan speed?
Commercial exact-model listings report 3200 RPM. This is consistent with SUNON's documented EE80251S1-0000-A99 catalog performance, but a separate exact D170-F99 manufacturer performance sheet was not independently located.

What airflow does EE80251S1-D170-F99 provide?
The published commercial airflow rating is 41.0 CFM, approximately 69.7 m³/h. This also matches the related EE80251S1 standard catalog configuration.

What is the maximum static pressure?
Exact-model suppliers report 0.18 inH2O, approximately 44.8 Pa. The same figure appears in SUNON's related EE80251S1 series performance table.

What bearing system does EE80251S1-D170-F99 use?
The complete model is identified as a sleeve bearing fan by commercial suppliers. The S designation in SUNON's model numbering system also identifies sleeve bearing construction.

What is the acoustical noise level?
Exact-model product listings report 33 dB(A), consistent with the related EE80251S1 catalog model. Actual installed noise can vary with mounting conditions, enclosure design and airflow restrictions.

How is EE80251S1-D170-F99 electrically connected?
Replacement listings specify three wire leads, commonly terminating in a three-pin connector. SUNON defines the F99 suffix as automatic restart with an R-type rotation detector signal on the third wire. This should not automatically be treated as a frequency-generator tachometer output or PWM control input. Confirm the actual connector, wire colors, polarity, output levels and signal requirements before integration.

What should be checked before ordering EE80251S1-D170-F99?
Confirm the complete SUNON model number including D170-F99, 12 VDC supply, 1.7 W rating, 80 x 80 x 25 mm frame dimensions, mounting-hole spacing, sleeve bearing type, three-wire connection, three-pin connector, wire polarity, R-type rotation detector interface, airflow direction and required cooling performance. The related EE80251S1-0000-A99 is a different functional configuration, while EE80252S1 models use 24 VDC. Do not automatically substitute these versions without verifying electrical, signal and mechanical compatibility.
