Alphacool ES and SL-15 fans support PWM speed control

Alphacool introduced the 80mm ES fan and the 120mm SL-15 fan. Both support speed control using a PWM signal applied to a four-pin connector.

Alphacool ES fans are specially designed for use in servers and workstations. Unlike classic plain bearings, they use a double ball bearing, which results in longer life at full load. These fans have several protection circuits. The rotation speed is adjustable in the range of 600-6000 rpm. The starting voltage is 7 V and the power consumption is 7.92 – 10.2 W. The maximum speed corresponds to a flow of 30.83 m³ / h and a noise of 50 dBA.

Fan Alphacool SL-15 is a special slim fan for radiators. With a thickness of 15 mm, it is well suited for use in small-sized PCs. It also uses a ball bearing. The rotation speed is adjustable in the range of 600-1800 rpm. The starting voltage is 7 V and the power consumption is 7.92 – 10.2 W. The maximum speed corresponds to a flow of 71.36 m³ / h and a noise of 32 dBA. MTBF is 50,000 hours.
