Adjustable PWM Fan with LED Display and Thermostat
Quiet continuous operation at 20% speed – ideal for acoustically optimized server cabinets
Automatic increase to 100% performance from approx. 35 °C – for reliable temperature control
PWM control with thermostat and sensor – no motherboard required, fully autonomous operation
LED display and temperature module – visual monitoring directly at the rack
Connection for up to 4 PWM fans – perfect for expansion or retrofitting
Axial fan with vapor bearing – durable, low-vibration, and especially quiet (28.3 dBA)
High airflow (101.24 m³/h) – efficient heat transfer with minimal noise
Compatible with all Lehmann acoustic variant cabinets – ready for immediate use
PWM Fan Control Settings:
The PWM fan runs continuously at 20% speed and reaches 100% speed at approximately 35 °C.
