FAN-0138L4 Supermicro Case Fan

High-Density Rack Cooling Fan Module for Chassis Airflow Continuity with the FAN-0138L4

The FAN-0138L4 is a Supermicro 92 x 92 x 38 mm 4-pin rack cooling fan module engineered to restore designed airflow paths in enterprise server chassis where sustained CPU and GPU boost states depend on stable inlet-to-exhaust pressure. In dense 1U/2U enclosures, fan performance directly governs thermal headroom for modern multi-core CPU platforms and accelerator-equipped nodes by preventing VRM, memory, and PCIe switch hotspots that can trigger frequency throttling.

Designed for systems using 4-pin PWM control, the FAN-0138L4 integrates with platform BMC fan curves to maintain predictable thermal behavior across mixed workloads such as virtualization, analytics, and AI inference. At up to 7500 RPM, it supports high static pressure needed for restrictive drive cages and heatsink fin stacks, helping preserve memory reliability under continuous load and safeguarding PCIe Gen4/Gen5 expansion zones where add-in cards raise localized heat density. As a non-hot-swap service part, the FAN-0138L4 is best aligned with planned maintenance windows to maintain fleet consistency and keep chassis airflow balanced.

Why Choose the FAN-0138L4?

The FAN-0138L4 provides an architecturally correct replacement path for maintaining original chassis thermals, enabling consistent density-to-performance operation without retuning datacentre thermal policies. It supports scalable deployments by standardizing airflow modules across identical server populations, reducing variance in fan control behavior, acoustic profiles, and component junction temperatures.

Supermicro designs service components to match chassis airflow engineering intent, prioritizing reliable operation under continuous duty cycles and compatibility with datacentre management standards. This approach helps ensure that replacement parts preserve platform validation boundaries and minimize unexpected thermal regressions after service events.

Key Applications:

• Chassis airflow restoration for rack servers
• Planned maintenance and service part replacement
• High-density compute node cooling support
• Virtualization and mixed workload clusters
