Ultra-quiet 40 mm case fan

This 4010 form-factor fan runs on 12 V and draws only 0.04 A, making it suitable for compact builds where low noise is a priority. Its ultra-quiet design targets systems that need steady airflow without audible distraction.

Sustained low-speed operation

Under continuous load the fan maintains its rated voltage and current without ramping to higher speeds, so acoustic output stays consistent. It is not intended for high-static-pressure scenarios or builds that demand maximum thermal throughput.

  • Ultra-quiet operation for low-noise builds
  • 12 V 0.04 A draw keeps power use minimal
  • 40 mm 4010 form factor fits tight spaces
