Key Features
Compact 40 x 40 x 20 mm Frame
The 40 mm square frame and 20 mm thickness provide a compact cooling format for compatible electronics. The manufacturer specifies four 4.3 mm mounting holes with 32 mm center spacing.
8200 RPM Rated Speed
The fan is rated at 8200 RPM with a ±15% tolerance. The documented air delivery is 10.8 CFM, making its performance suitable for evaluation in compact forced-air cooling designs.
Vapo Bearing Technology
The manufacturer specifies a precision Vapo bearing system, PBT thermoplastic housing and impeller, and a published acoustical noise rating of 27.5 dB(A).
Three-Wire Tachometer Signal
The third yellow wire provides an open-collector frequency generator signal for rotational speed monitoring. This is a monitoring signal, not a documented PWM speed-control input.
Automatic Restart Protection
The manufacturer documents automatic restart when a locked rotor condition is removed. The product specification lists 70000 hours of life expectancy under defined laboratory conditions, which is not a guarantee for every installation.
Applications
- Compact industrial control electronics cooling
- Network switch and router ventilation
- Telecommunications equipment thermal management
- Embedded computing equipment cooling
- Electronic power supply ventilation
- Small electronic enclosure airflow management
- Cooling assemblies requiring fan speed feedback
- Replacement of compatible 40 mm three-wire DC axial fans

Frequently Asked Questions
What is SUNON MB40201VX-000U-G99?
It is a SUNON MagLev MB-series DC brushless axial cooling fan with a 40 x 40 x 20 mm frame and a three-wire electrical connection.
What is the rated voltage of MB40201VX-000U-G99?
The manufacturer specifies 12 VDC, with an operating voltage range of 4.5-13.8 VDC and a starting voltage of 4.5 VDC at 25°C.
What are the dimensions of MB40201VX-000U-G99?
The frame measures 40 x 40 x 20 mm, with four 4.3 mm mounting holes on a 32 mm square mounting pattern.
What is the rated current?
The manufacturer specifies 0.115 A rated current and 0.133 A maximum current.
What is the power consumption?
The rated power is 1.38 W, with a manufacturer-specified maximum power consumption of 1.60 W.
What is the rated fan speed?
The specified rated speed is 8200 RPM, with a tolerance of ±15% at rated voltage.
What airflow does MB40201VX-000U-G99 provide?
The SUNON datasheet specifies 10.8 CFM, equivalent to approximately 0.302 m³/min.
What is the static pressure rating?
The documented static pressure is 0.27 inH2O, equivalent to approximately 67.3 Pa.
What bearing system does the fan use?
It uses SUNON's precision Vapo bearing system. The manufacturer specifies 27.5 dB(A) acoustical noise under its test conditions.
What are the three wire connections?
The manufacturer's mechanical drawing identifies red for positive power, black for negative power, and yellow for the frequency generator speed signal. The yellow output is open collector and must be connected using a compatible sensing circuit.
Does MB40201VX-000U-G99 support automatic restart and PWM control?
The manufacturer confirms automatic restart after a locked rotor condition is cleared. A PWM speed-control input is not specified; the datasheet advises against using power-line or ground-line PWM for speed adjustment.
What should be checked before ordering MB40201VX-000U-G99?
Verify the complete model number, 12 VDC supply, 0.115 A rated current, 40 x 40 x 20 mm dimensions, 32 mm mounting spacing, Vapo bearing, wire length, red-black power polarity, yellow tachometer signal and required airflow. Confirm connector termination and compatibility before replacing another 40 mm fan. The MB40201VX-000U-G99 is listed as discontinued by major electronic component distributors, and a suggested similar model is not automatically an electrically or mechanically identical replacement.
