R124020BL(4) high-speed 4020 axial cooling fan is built for 1U and 2U server thermal management and industrial cooling projects. Powered by DC12V, the 4-wire PWM design dynamically adjusts rotational speed to balance cooling power and noise level according to real-time internal temperature. Equipped with dual ball bearings, the fan maintains stable high-speed airflow, withstands continuous vibration and supports 24/7 nonstop heavy-duty operation. The compact 40x40x20mm footprint is ideal for densely packed server chassis, CPU heatsink assemblies and small industrial power hardware. Simple direct fan swap restores thermal performance, prevents component overheating and thermal throttling, and extends the lifespan of your server and industrial equipment.
