PWM Fan Upgrade Now Available for Silent and Acoustic Server Cabinets
by Andreas Fischer
Lehmann IT introduces a new PWM fan upgrade designed for silent server cabinets and acoustic racks. The system provides quieter operation, improved cooling performance and more precise temperature regulation for environments where low noise levels are essential.
The PWM fan system adjusts its speed automatically based on the internal temperature of the cabinet. When the thermal load is low, the fans run at reduced speed, keeping the cabinet extremely quiet. As the temperature rises, the fans increase their speed smoothly and precisely, ensuring reliable cooling without sudden noise spikes. This makes PWM cooling ideal for office racks, studio racks and mixed‑use rooms.
The integrated PWM controller continuously monitors the cabinet climate and regulates the fans without requiring manual adjustments. This controlled ventilation improves temperature stability, prevents heat buildup and protects sensitive IT hardware during long‑term operation.
Another advantage of the PWM fan upgrade is reduced energy consumption. Because the fans only run as fast as necessary, power usage remains low, contributing to a more efficient overall system.
The new PWM fan system is available for several Lehmann IT cabinet models and can be installed in both new and existing configurations. Customers benefit from quieter operation, better temperature control and a more reliable long‑term cooling solution.
