Supermicro 40x28mm Fan Holder

The Supermicro MCP-320-81302-0B is a dedicated CPU fan adapter designed to secure a single 40x28mm fan. It serves administrators maintaining SuperChassis 504-203B, SC505 203B, or SuperServer 5017A-EP systems. This new component ensures correct fan alignment within compatible server enclosures. Builders needing different fan dimensions or chassis mounts should select an alternative bracket.

Thermals Noise and Power Draw

The passive holder adds no electrical load and generates no acoustic signature of its own. Thermal performance and noise levels depend entirely on the specific 40x28mm fan installed by the user. The adapter simply provides the mechanical interface required for standard airflow paths in the listed Supermicro platforms. No power connectors or control circuitry are present on this accessory.

Questions about this item

How do I install the MCP-320-81302-0B fan holder and what step is often missed?

Mount the holder onto the chassis fan bracket using the existing screw holes, then secure the 40x28mm fan inside; the step often missed is orienting the fan airflow arrow toward the CPU heatsink before tightening the four corner screws.

What maintenance will the MCP-320-81302-0B fan holder need later?

The plastic holder itself requires no maintenance; plan to replace the 40x28mm fan when its bearings become noisy or airflow drops, typically after several years of continuous server operation.
