Middle Cooling Fan for SC813MF Chassis

This 40 mm axial fan is designed as a direct replacement for Supermicro SC813MF chassis. It draws 1.05 A through a standard 4 pin connector and spins at 22,500 RPM to deliver 28.6 CFM of airflow.

Fits CSE-113MFTS, CSE-801LTS and CSE-813MFTS Series

The 40 x 40 x 28 mm frame slides into the middle cooling position of the listed chassis families without adapters. Its four pin connector plugs straight into the board header, freeing builders from sourcing custom brackets or cables.

Sustained Operation at 61 dBA

At full speed the fan maintains 22,500 RPM continuously, moving 28.6 CFM while emitting 61 dBA. The Nidec motor is rated for constant duty in server environments where airflow must remain stable over long periods.

Questions about this item

At 22,500 RPM, does the 40 mm fan hit its thermal limit before the chassis airflow can keep up?

The fan delivers 28.6 CFM at its rated 22,500 RPM and is certified for the SC813MF chassis, so airflow matches the chassis design envelope.

Running at 61 dBA and 1.05 A continuously, how much heat and noise should I expect in a populated rack?

At full speed the unit draws 1.05 A and produces 61 dBA; thermal load scales with the chassis population and rack airflow.

Beyond a 4-pin header, what mounting points or chassis brackets must my system already have?

It fits the 40 x 40 x 28 mm middle-fan bay in CSE-113MFTS, CSE-801LTS and CSE-813MFTS series chassis.
