Compact 40 mm case fan

The BI-Sonic BS401012M is a 40 mm square DC cooler designed for tight case spaces. It runs on 12 V and draws 0.09 A through a three-pin connector. The straight-blade design delivers focused airflow without LED lighting. Its 10 mm thickness keeps the profile slim for restricted clearance.

Suits small-form-factor builds

Builders assembling compact chassis or replacing a noisy 40 mm unit will appreciate the direct-fit dimensions and three-pin speed control. Systems that require larger fans, PWM regulation or RGB illumination should consider other options. The fixed voltage rating also limits use in 5 V or variable-voltage headers.

Three-pin connector simplifies installation

The bundled three-wire plug connects straight to standard motherboard or controller headers, enabling basic speed monitoring. No additional adapters, mounting screws or software utilities are included, so cable routing and hardware fastening remain the builder's responsibility.

Questions about this item

What voltage header does the 40 mm BS401012M need on my motherboard?

It runs on a 12 V DC supply through its three-pin connector.

Will the 4010 cooler fit in the same 40 mm cut-out as my old fan?

Yes, the frame measures 40 by 40 by 10 mm, matching the standard 40 mm mounting pattern.

How can I confirm the BS401012M is spinning after I connect it?

The three-wire lead includes a tachometer signal so the BIOS or monitoring software will report its RPM.
