The Server Fan 4056 with a rotational speed of 30000RPM is a high-performance cooling component designed for enterprise-grade server environments where extreme heat dissipation is critical. Measuring 40mm in width and 56mm in depth (following the industry-standard 40x56mm form factor), this fan balances compact dimensions with powerful airflow capabilities, making it ideal for dense server chassis or blade server configurations where space is limited.

At 30000RPM, the fan delivers exceptional static pressure, typically ranging from 80 to 120 Pascals (Pa)—a key metric for overcoming airflow resistance in server enclosures filled with heat-generating components like CPUs, GPUs, and storage drives. Airflow output averages between 18 and 25 cubic feet per minute (CFM), ensuring efficient heat transfer across heat sinks and internal server components. The fan utilizes a brushless DC (BLDC) motor, which offers several advantages over traditional brushed motors: lower power consumption (typically 12V DC with a current draw of 0.8 to 1.2A), reduced electromagnetic interference (EMI) to avoid disrupting server electronics, and a longer operational lifespan (up to 60,000 hours MTBF, or Mean Time Between Failures).

To enhance reliability, the 4056 30000RPM fan often includes features like pulse-width modulation (PWM) control, allowing dynamic speed adjustment based on real-time temperature data from server sensors—this optimizes cooling efficiency while minimizing noise during low-load periods (though noise levels can reach 55 to 65 decibels (dB) at full speed, requiring sound dampening in noise-sensitive environments). Additionally, many models incorporate dual-ball bearings, which outperform sleeve bearings in high-speed applications by resisting wear and tear, even in continuous operation at 30000RPM. Compatibility-wise, it adheres to standard server fan connectors (e.g., 4-pin PWM) for seamless integration with major server brands like Dell, HP, and Lenovo.
