FAN-0154L4 Supermicro 22500RPM Case Fan

High-Performance 40mm Server Fan Module for Chassis Airflow Integrity with the FAN-0154L4

The FAN-0154L4 is a Supermicro 40mm high-speed fan module engineered to maintain deterministic airflow in dense rack server chassis where CPU, GPU, memory, PCIe, and storage thermals converge. By sustaining controlled pressure and localized cooling, the FAN-0154L4 helps protect platform stability under sustained compute and I/O loads, including multi-core CPU nodes, accelerator-enabled configurations, and memory-intensive systems that run continuously at high utilization.

In modern server architectures, higher PCIe lane counts, NVMe backplanes, and compact heatsink designs increase thermal density and reduce tolerance for airflow variance. The FAN-0154L4 supports a 4-pin control interface for predictable fan management policies and integrates as a non hot-swap module for fixed, service-window maintenance models. With a 40 x 40 x 28mm assembly and a nominal 22,500 RPM speed, the FAN-0154L4 is suited to chassis zones that require high static pressure to move air through restrictive fin stacks and tightly packed component layouts.

Why Choose the FAN-0154L4?

The FAN-0154L4 delivers targeted airflow where chassis impedance is highest, enabling consistent thermals that preserve CPU boost behavior, GPU clock stability, and storage reliability during sustained workloads. For enterprise operations, the FAN-0154L4 supports scalable deployment across homogeneous racks, simplifies spares planning, and aligns with service practices where non hot-swap parts are replaced during scheduled maintenance to protect uptime.

Supermicro designs cooling components with a focus on system-level compatibility, validated control behavior, and reliability under data centre environmental constraints. Built to integrate with Supermicro chassis airflow channels and management logic, the FAN-0154L4 supports consistent operation in standardized rack deployments and helps maintain compliance with facility temperature and acoustic planning.

Key Applications:

• Rack server chassis cooling and airflow maintenance
• High-density compute nodes with restrictive heatsink zones
• NVMe and PCIe expansion cooling in compact enclosures
• Edge racks requiring high-RPM localized airflow
