LSI 9305-24i HBA Fan Shroud / Active Cooling Duct

A 3D-printed fan shroud designed to provide active cooling for the LSI 9305-24i SAS HBA (and similar full-height PCIe cards). These cards run notoriously hot, especially in compact or low-airflow chassis where passive heatsinks alone aren't enough.

The shroud ducts airflow from two Noctua NF-A4x10 FLX 40mm fans directly over the card's heatsink, significantly reducing operating temperatures. The sides feature a isogrid ventilation pattern for airflow exhaust while maintaining structural rigidity.

Features:

• Direct-mount fan shroud for active HBA cooling
• Sized for the Noctua NF-A4x10 FLX (40x10mm)
• Isogrid side ventilation for airflow exhaust
• Designed to fit in standard PCIe slot spacing

Print Settings:

• No supports needed
• PETG or ASA recommended for heat resistance near warm components
• PLA will work but may soften over time in high-temp environments
