Small square 7cm PWM case fan black frame four wires

Fans

Fans 2806KL-04W-B56 7015 12V 4-wire PWM case fan

SKU CH-4XSB-XPN9N

A 7 cm 12 V PWM case fan with double-ball bearing runs from 600 to 3300 rpm delivering 45.0 cfm at 15–28.5 dBA

  • 7 cm compact frame fits tight chassis builds
  • Double ball bearing extends operating life at 3300 rpm
  • PWM control adjusts speed from 600 rpm for quiet idle
  • 0 cfm airflow at full speed cools demanding components
  • 15–28.5 dBA noise range keeps acoustics low under load

Compact 70 mm PWM case fan

The Fans 2806KL-04W-B56 7015 is a 7 cm square, 1.5 cm thick frame that fits standard 70 mm mounting holes in small-form-factor chassis. It runs on 12 V DC and draws 0.28 A, making it suitable for tight builds where a low-profile axial cooler is required.

Four-wire PWM speed regulation

The 4-wire connector enables motherboard-controlled PWM duty cycles so the fan spins between 600 and 3300 rpm ± 5 % without manual switches. Airflow reaches 45.0 cfm at full speed while acoustic output stays between 15 and 28.5 dBA across the range.

Double ball bearing durability

NMB double ball bearings reduce wear compared with sleeve designs, supporting continuous operation in industrial or medical environments listed by the manufacturer. The 7015 footprint and standard screw pattern allow drop-in replacement on existing 70 mm mounts without adapter brackets.

Questions about this item

How long will the double ball bearing last before it needs replacing?

The double ball bearing is rated for continuous operation across the full 600 to 3300 rpm range and typically outlasts sleeve-bearing alternatives by a wide margin.

At what point does the 0.28 A current draw become the limiting factor during sustained load?

The fan draws a steady 0.28 A at 12 V, so the motherboard header or fan controller will reach its current limit before the fan itself does.

How loud is the fan when it runs at 3300 rpm all day?

At maximum speed the noise level is 28.5 dBA, dropping to 15 dBA at the 600 rpm minimum while maintaining 45.0 cfm airflow at full speed.
