GEO-S2501B-3 Geometric Future 2501W 3-pack Case Fan

High-Performance 120mm PWM Server Cooling Component for predictable chassis airflow with the GEO-S2501B-3

The GEO-S2501B-3 is a 12V 4-pin PWM 120 x 25mm fan engineered to stabilise server and workstation thermal envelopes where consistent static pressure and controllable acoustics are required. In mixed CPU and GPU configurations, the GEO-S2501B-3 supports fine-grained fan curve control via standard PWM headers, enabling platform firmware or BMC policies to react to rapid load transients without overshooting noise or power targets.

Designed for modern dense chassis layouts, the GEO-S2501B-3 integrates into common fan walls and replacement mounts using the standard 120mm footprint, simplifying service procedures and spares strategy. Up to 2000 RPM provides headroom for restrictive filters, heatsink arrays, and high-density storage zones, while maintaining predictable airflow paths that protect PCIe add-in cards, memory banks, and VRM zones from localised hotspots.

Why Choose the GEO-S2501B-3?

The GEO-S2501B-3 delivers a pragmatic density-to-performance balance for enterprise deployments that require repeatable cooling behaviour across fleets. By standardising on the GEO-S2501B-3, IT teams can improve operational consistency, reduce variability between chassis revisions, and scale cooling capacity through modular fan wall design while keeping maintenance workflows aligned with standard 4-pin PWM control.

Geometric Future focuses on mechanical fit accuracy, stable motor control, and deployment-friendly component design intended for long service cycles. The result is a cooling component aligned with contemporary data centre expectations for predictable integration, serviceability, and system-level thermal governance.

Key Applications:

• Server and workstation fan wall replacement
• Chassis airflow optimisation for GPU nodes
• General system cooling for storage and VRM zones
• Spare part standardisation for fleet operations
