FAN-0163L4 Supermicro 23300RPM Case Fan

High-Pressure 40mm Server Chassis Fan Module for Dense 1U/2U Airflow Maintenance with the FAN-0163L4

The FAN-0163L4 is a Supermicro 40mm high-RPM chassis fan module engineered to restore designed airflow paths in compact 1U/2U server platforms where CPU and GPU boost behavior depends on stable inlet-to-exhaust pressure. In modern dual-socket CPU systems and GPU-dense nodes, memory bandwidth and sustained PCIe traffic can push localized thermal zones; the FAN-0163L4 is deployed to re-establish the static pressure required to keep heatsinks, VRM zones, and mezzanine expansion areas within validated operating limits.

As PCIe Gen4/Gen5 expansion and NVMe storage density increase, chassis impedance rises and airflow margins shrink. The FAN-0163L4 addresses this by operating in a 23,300 RPM speed class with a 4-pin connector for system-managed PWM control, enabling the baseboard management stack to maintain predictable fan curves under mixed workloads such as virtualization, AI inference, and storage-heavy services. The non-hot-swap form factor supports planned maintenance cycles to recover thermal headroom without altering the platform’s mechanical design.

Why Choose the FAN-0163L4?

The FAN-0163L4 provides a direct, service-part route to preserve the density-to-performance profile of Supermicro chassis by returning airflow and pressure characteristics to their original specification. For enterprise operations, the FAN-0163L4 supports repeatable thermal behavior across fleets, reduces risk of frequency throttling, and aligns with scalable maintenance practices where consistent acoustics and control integration matter.

Supermicro designs cooling modules with an emphasis on chassis-level airflow engineering, component longevity, and operational reliability in data centre environments, ensuring compatibility with server management standards and validated thermal envelopes.

Key Applications:

• Planned chassis fan replacement in 1U/2U servers
• Restoring thermal headroom for CPU/GPU compute nodes
• High-density NVMe storage servers with restricted airflow
• Virtualization and mixed enterprise workloads
