Compact 40mm 5V fan for tight builds

This 40 by 40 by 10 millimetre frame fits small-form-factor cases, rack units or embedded boards where larger fans cannot mount. It draws 0.12 amps from a 5 volt rail and connects through a standard three-pin header so speed reporting is available.

5 to 10 dBA acoustic ceiling at full speed

The double ball bearing spins counter-clockwise and stays within a 5 to 10 dBA band, which is audible in a silent room but masked by typical component noise. Rated voltage tolerance is plus or minus 15 percent, so a clean 5 volt supply keeps it inside the published range.

PBT glass-fibre frame

Both frame and impeller use PBT with 30 percent glass fibre and VO flame-retardant grade, giving structural rigidity without metal weight. Insulation resistance exceeds 500 megohms, and the bearing is specified for 80 000 hours at 25 degrees ambient across an operating window of minus 10 to plus 70 degrees Celsius.

How loud is 5 to 10 dBA inside a PC case?

At 5 to 10 dBA the fan is near-silent; most users will not hear it over other components.

What does the 3-pin connector limit for speed control?

The 3-pin header supports voltage-based regulation only; PWM duty-cycle control is not available.
