120 mm ball-bearing case fan delivering 93 CFM at 2100 RPM with 37 dB-A noise

  • Air Flow30-35 CFM
  • High airflow of 93 CFM keeps components cool
  • Double ball bearing rated for 50000 hours of operation
  • Quiet 37 dB-A noise level at full speed
  • 12 V 2.9 W design limits power draw
  • B-class insulation withstands 155 degrees Celsius

Purpose-built airflow for compact enclosures

This 120×120×38 mm case fan delivers 93 CFM at 2100 RPM from a 12 V, 2.9 W motor. The double ball bearing design targets 50000 hours of operation. It suits builders who need directed cooling in tight server or workstation chassis where space is limited.

Thermals, noise and power in normal use

At the rated 0.24 A draw the fan produces 37 dB-A while moving 30–35 CFM through typical system resistance. B-class enamel insulation withstands 155 °C winding temperature. The anticlockwise rotation and plastic blades keep vibration low during continuous duty.

Behaviour under sustained load

The ball bearing construction maintains speed stability over long runs without the wear seen in sleeve alternatives. Rated life of 50000 hours assumes constant 12 V input at ambient conditions. Buyers who need variable-speed control or PWM signalling should verify compatibility before purchase.

Questions about this item

How do I install this 120×120×38 mm fan and which step do people get wrong?

Mount the fan using the four corner holes with the airflow arrow pointing into the case; the step often missed is wiring the two-pin 12 V lead to a motherboard header or fan controller instead of leaving it loose.

What maintenance or replacement will the double ball bearing need later?

The double ball bearing is rated for 50000 hours at 155 °C insulation class; after that interval expect rising noise and plan a full fan swap rather than relubrication.

What limit shows up first under sustained 2100 RPM operation?

Continuous running at 2.9 W and 37 dB-A will hit the bearing life limit of 50000 hours before thermal or voltage thresholds become an issue.
