Supermicro FAN-0165L4 Counter-Rotating Fan

Supermicro FAN-0165L4 is a counter-rotating cooling fan engineered for demanding server and professional IT infrastructures. It is intended for use as a dedicated replacement or spare fan module in compatible Supermicro systems, where reliable airflow and stable thermal conditions are critical for hardware longevity and performance.

Counter-rotating fan architecture typically enables higher static pressure compared with standard single-rotor fans, which is particularly important in high-density chassis with restricted airflow paths, densely populated drive bays or high-power CPUs and memory modules.

• Application: designed for integration in selected Supermicro server and workstation platforms as a system cooling component.
• Construction: counter-rotating design to support efficient airflow in constrained server chassis environments.
• Operational profile: suitable for continuous operation in data center, enterprise and lab infrastructures, subject to chassis compatibility.
• Reliability: intended to maintain stable cooling performance to help protect components against thermal throttling and overheating.
• Warranty: 12‑month manufacturer warranty for added assurance in professional deployments.

Key benefits:

• Thermal stability: supports consistent system temperatures, which can contribute to sustained performance under high workloads.
• Service continuity: as a replacement fan, it helps restore or maintain proper airflow in existing Supermicro configurations, reducing potential downtime.
• Predictable integration: using an original Supermicro-designated fan module helps ensure mechanical and electrical compatibility with supported chassis models.

Before purchase and installation, verify compatibility of the Supermicro FAN-0165L4 with the specific server or chassis model using the official Supermicro documentation or system configurator.
