Memory fan assembly HP 809055-001 for server/motherboard cooling

Replacement memory fan assembly HP 809055-001 designed to provide targeted cooling for memory modules and adjacent board components. Intended for installation in compatible HP server systems, this assembly helps maintain stable operating temperatures for DIMMs and nearby circuitry, reducing the risk of thermal throttling and supporting longer component life. The part is a direct-swap style fan assembly for repairs and routine maintenance where the original HP memory fan module is required.

Advantages

The memory fan assembly delivers focused airflow to memory slots and surrounding components, enabling more consistent thermal performance under load. Its form factor and connector type match compatible HP system layouts to simplify replacement. Using a correct OEM-style fan assembly minimizes installation time and reduces the likelihood of compatibility issues compared with generic cooling parts.

Suitable for

• Replacing a failed or noisy memory fan assembly in compatible HP servers
• Routine maintenance or preventive replacement to ensure stable DIMM temperatures
• System repairs when restoring original cooling configuration after component upgrades

Key specifications

• Function: targeted cooling for memory modules and adjacent motherboard components
• Compatibility: designed for use in compatible HP server/motherboard configurations
• Form factor: compact fan assembly suitable for slot‑adjacent installation on server board
• Airflow: directed airflow profile to concentrate cooling over DIMM locations
• Connector interface: board-mounted connector matching HP server power and control signals
• Mounting: designed for direct replacement with matching screw or snap points

How to use

Power down the server, disconnect power sources and follow ESD precautions before beginning. Remove any chassis covers necessary to access the memory fan area, then disconnect the fan assembly power connector from the motherboard. Unscrew or unclip the existing fan assembly and lift it free. Position the replacement memory fan assembly in the same orientation, secure it using the original fasteners or clips, and reconnect the fan power connector. Reinstall chassis covers, reconnect power, and verify fan operation and system thermal monitoring during initial boot.

Recommendations

Inspect fans and airflow channels periodically for dust buildup and replace the assembly if bearings become noisy or rotation is unstable. Use the matching HP-style fan assembly for reliable electrical and mechanical fit; avoid modifying connectors or mounting points. When servicing multiple cooling components, document connector positions and cable routing to maintain correct airflow paths after reassembly.
