Compact 40 mm 12 V case fan

The SunnyStar SHBC0412SH is a 40 mm square case fan designed for tight spaces such as small-form-factor PCs, routers or network switches. It runs on a 12 V supply and draws 0.11 A through a two-pin power connector. The sleeve bearing keeps the acoustic profile low for noise-sensitive builds.

Sleeve bearing limits at low RPM

The sleeve bearing and sub-1600 RPM ceiling mean airflow is modest and suited to spot cooling rather than high-static-pressure radiators. Noise stays between 15 and 20 dBA, but the bearing type can develop wear faster than ball or fluid-dynamic alternatives if the fan is mounted horizontally or run continuously at elevated temperatures.

Verify voltage, connector and clearance

Confirm the target device supplies 12 V on a two-pin header; the fan has no PWM lead for speed control. Measure the mounting holes — 40 mm centre-to-centre — and ensure 10 mm depth fits inside the chassis or router enclosure. The black frame carries no LEDs, so it suits stealthy or industrial aesthetics.

Questions about this item

Which bearing type suits a quiet 40 mm build?

The sleeve bearing keeps noise between 15 and 20 dBA at speeds below 1600 RPM.

What airflow can I expect from the 12 V 0.11 A motor?

At under 1600 RPM the fan moves enough air for tight router, switch or CPU cooler spots.

Will the 2-pin connector limit speed control on my board?

The 2-pin DC plug runs at fixed 12 V; PWM control is not supported.
