The San Ace 60CR measures 60-mm square and 76 mm and is said to have the highest airflow (2.26 cu m/min) and static pressure (550 Pa) in the industry. It uses two axially aligned fans rotating counterclockwise to each other. Power consumption is as low as 32.4 W, minimum noise is 64 dB, and L10 life expectancy is 40,000 hr at 60°C. The cooling fan is also RoHS compliant. Optional features include tachometer sensor and lock rotor sensor outputs, and pulse-width-modulation control, which lets the fans' rotational speeds be controlled to lower noise and power consumption.
