FAN-0133L4 Supermicro Case Fan

High-Density Rack Server Cooling Fan Module engineered for controlled chassis airflow with the FAN-0133L4

The FAN-0133L4 is an 80x38mm high-speed PWM fan assembly designed as a direct-fit server component to sustain engineered airflow paths in Supermicro rack platforms. In modern CPU- and GPU-dense nodes, thermal stability depends on maintaining front-to-back pressure and predictable fan curves; the FAN-0133L4 supports this control model through a 4-pin PWM interface that enables closed-loop regulation from the baseboard management controller.

As server architectures shift to higher core-count CPUs, persistent memory footprints, and PCIe expansion for accelerators and NVMe storage, localized heat density increases around VRMs, DIMMs, and add-in cards. The FAN-0133L4 targets restricted airflow environments with high static-pressure capability at up to 11,000 RPM, helping preserve component operating limits under sustained load. In chassis designs with multiple fan zones, using the FAN-0133L4 as the specified replacement helps keep acoustic, thermal, and power characteristics aligned with the platform’s original qualification.

Why Choose the FAN-0133L4?

The FAN-0133L4 provides a reliable, serviceable path to restore manufacturer-intended cooling performance without redesigning airflow or retuning platform policies. For enterprise deployments, the FAN-0133L4 supports consistent density-to-performance operation by enabling precise PWM control, predictable ramp behavior, and fast recovery during thermal transients, making it suitable for standardized spares and field replacement at scale.

Supermicro engineers cooling assemblies to match chassis impedance, sensor logic, and long-duration datacenter duty cycles. The FAN-0133L4 follows this qualification approach, supporting modern serviceability expectations, connector standards, and integration with platform management for dependable operations in continuous workloads.

Key Applications:

• Rack server system fan replacement
• High-density chassis airflow maintenance
• Datacenter spares and field service inventory
• Thermal stabilization for PCIe and NVMe expansion nodes
