140 mm AC 100 V case fan
This 140 mm axial fan operates on AC 100 V mains power and draws 0.15 A at 60 Hz or 0.17 A at 50 Hz. It is intended for builders who need direct mains-driven airflow inside enclosures that already provide a 100 V supply.
Mains voltage and fixed speed
The fan runs at line frequency, so its speed is tied to 50 Hz or 60 Hz mains and cannot be PWM-controlled or voltage-regulated by a typical motherboard header. Builders who need variable speed control or low-voltage header connection should look elsewhere.
Double ball bearing rated 50 000 hours
A maintenance-free double ball bearing provides an L10 lifetime of 50 000 hours at 25 °C, making bearing durability the key specification for continuous-duty cooling in industrial or server chassis.

Questions about this item
Which voltage version should I pick for a 100 V AC supply?
The MU1428S-11 is rated for AC100V at 50Hz or 60Hz, drawing 0.15A at 60Hz and 0.17A at 50Hz, so it matches a standard 100 V line directly.
What does the 42 dBA noise figure mean once the fan is installed in a case?
At 42 dBA the fan produces a moderate hum audible in a quiet room but typically masked by other components inside a closed chassis.
How does the double ball bearing and Class B insulation affect long-term use?
Maintenance-free double ball bearings are rated for 50,000 hours L10 life at 25 °C, while Class B insulation withstands higher operating temperatures for reliable continuous running.
