Key Features
50 mm Compact Frame
The fan uses a nominal 50 x 50 mm square frame. Documented suffix versions and commercial listings show different thicknesses, so installation depth must be confirmed before replacement.
0.6 W Listed Power Rating
Multiple replacement-fan listings identify a 0.6 W power rating for KDE1205PFV4, corresponding to a calculated current of approximately 0.05 A at 12 VDC.
Magnetic Suspension Design
Commercial product descriptions identify magnetic suspension bearing construction for this KDE-series fan. Confirm the exact bearing designation where required by maintenance specifications.
Two-Wire Power Connection
The documented B4177 and B1566 suffix assemblies use two-wire, two-pin connections. Their cable lengths and mechanical dimensions differ, making exact suffix matching important.
Compact Equipment Ventilation
The axial fan format supports localized forced-air cooling in compatible computer and electronic equipment. Airflow, operating speed and acoustical values should be checked against documentation for the actual supplied configuration.
Applications
- Compact computer chassis cooling
- Small server fan replacement after compatibility verification
- Embedded computing equipment ventilation
- Compact industrial control electronics cooling
- Network communication equipment thermal management
- Small electronic enclosure airflow management
- Localized forced-air cooling of circuit assemblies
- Replacement of compatible 50 mm DC axial cooling fans

Frequently Asked Questions
What is SUNON KDE1205PFV4?
KDE1205PFV4 is a SUNON KDE-series DC brushless axial cooling fan identified in compact computer and electronic equipment replacement applications.
What is the rated voltage of KDE1205PFV4?
The documented rated supply voltage is 12 VDC.
What are the dimensions of KDE1205PFV4?
The fan has a nominal 50 x 50 mm square frame. Documented B4177 and B1566 suffix configurations measure 12 mm and 15 mm thick respectively, while some commercial listings specify 10 mm. Confirm the complete suffix and physical dimensions.
What is the power consumption?
Multiple supplier listings and replacement-part records identify a 0.6 W power rating.
What is the rated current?
Dividing the listed 0.6 W power by 12 V gives approximately 0.05 A. This is a calculated figure rather than an independently confirmed manufacturer current specification.
What is the fan speed?
Some commercial listings specify 5200 RPM, but a manufacturer speed rating for the exact KDE1205PFV4 suffix configuration has not been independently confirmed.
What airflow does KDE1205PFV4 provide?
Certain suppliers list 6.3 CFM. Confirm the manufacturer's airflow specification for the complete fan version before relying on this figure for cooling calculations.
What bearing system does the fan use?
Commercial product listings describe a magnetic suspension bearing. The precise bearing specification should be checked against the full product designation.
What is the acoustical noise level?
Some supplier descriptions list 18 dB(A), but an exact manufacturer noise specification for the complete KDE1205PFV4 configuration was not established.
Does KDE1205PFV4 use a two-wire connection?
Documented replacement assemblies commonly use a two-wire, two-pin connection. Verify wire polarity and connector dimensions before installation.
Are all KDE1205PFV4 fans mechanically identical?
Not necessarily. Documented suffix configurations include 50 x 50 x 12 mm and 50 x 50 x 15 mm versions with different cable lengths. Matching only KDE1205PFV4 is insufficient to guarantee mechanical interchangeability.
What should be checked before ordering KDE1205PFV4?
Verify the complete model and suffix, 12 VDC supply, 0.6 W rating, actual frame thickness, mounting-hole pattern, cable length, two-pin connector, electrical polarity and cooling requirements. Do not assume that KDE1205PFV1, KDE1205PFV2 and KDE1205PFV4 have interchangeable performance or dimensions.
