  • Precise speed monitoring via third wire tachometer signal
  • Compact 80 mm square frame fits tight case spaces
  • Rated 50000 hours operating life for long-term reliability

80 mm 5 V magnetic-suspension fan

The SXDOOL MF80250V4-1Q03A-F99 is an 80 mm square frame fan built for low-voltage cooling in compact enclosures. It draws 0.122 A at 5 V for 0.61 W and spins at 2100 RPM on a special magnetic-suspension bearing rated for 50000 hours. The three-wire lead provides power and a yellow speed-sense line for monitoring.

5 V three-wire interface limits

Operation is restricted to a 5 V supply, so the fan cannot be connected directly to standard 12 V headers without a step-down or adapter. The third wire reports rotational speed only; it does not accept PWM control, so the motor runs at its fixed 2100 RPM whenever powered. Voltage regulation is the only way to alter airflow or noise.

0.61 W headroom and bearing life

At 0.61 W the unit suits tight spaces such as small-form-factor cases, NAS boxes or industrial chassis where a single 80 mm slot is available. The magnetic-suspension bearing extends service life but the fixed speed and single-voltage design leave no margin for higher static-pressure demands or variable thermal curves.

Questions about this item

Should I pick the 3-wire version or a 4-wire PWM fan for my motherboard?

The 3-wire design uses black, red and yellow leads for ground, 5 V power and speed signal; it runs at a fixed 2100 RPM, so choose it when your header does not support PWM control.

What does 2100 RPM actually deliver in a live system?

At 2100 RPM the fan moves air quietly through the 80 mm frame while drawing only 0.122 A at 5 V, giving steady airflow for compact chassis or heatsink cooling.

How does the special magnetic suspension bearing affect longevity?

The magnetic suspension bearing is rated for 50000 hours of continuous operation, reducing friction and wear compared with traditional sleeve or ball bearings.
