Pulse Width Modulation (PWM) Fans

NMB Technologies Pulse Width Modulation (PWM) Fans are high-performance, four-wire fans with a tachometer signal. The energy-saving fans offer efficient motor technology with an aerodynamic impeller design. The fans feature low vibration, low noise, tacho output, PWM speed control, and current spike prevention. The PWM feature extends the life of the fan with a more efficient performance. NMB PWM Fans are designed for demanding applications such as routers, switches, storage, inverters, telecom, data storage, and uninterruptible power supplies (UPS).
