Fans MF20C-05LA 5 V 0.06 A 20 mm case fan

SKU CH-49RJ-JQQYR

A 20 mm square, 5 V DC case fan drawing 0.06 A with a three-wire connector for server cooling

  • Compact 20 mm frame fits tight server chassis
  • Low 5 V draw reduces power load
  • Quiet 3-wire operation for stable airflow
  • Light 0.06 A current eases PSU demand

Compact 5 V case fan for tight spaces

This 20 mm square fan runs on 5 V DC and draws 0.06 A through a three-wire connector. It fits server chassis and small-form-factor cases where larger coolers will not mount. The slim 8 mm profile allows installation in narrow ducting or between densely packed cards. It is sold new and ready for immediate use.

Suited to low-voltage cooling in confined bays

Technicians maintaining legacy 5 V backplanes or custom embedded boards will find the voltage and pin-out match their requirements. Builders who need higher airflow, PWM speed control or a larger frame should consider other options.

Questions about this item

How can I confirm the 5 V fan is spinning correctly after connecting the 3-wire plug?

The 3-wire connector provides a tachometer signal so the motherboard or fan controller can report RPM in BIOS or monitoring software.

What comes with the MF20C-05LA and what must I source separately?

The package includes the 20 mm square fan with its 3-wire lead; mounting screws, a 5 V header adapter or a fan controller are not supplied.
