The fans generate half the noise and use 26% less power than other models from Sanyo Denki yet have similar airflow and static pressure, said EAO. A built-in pulse sensor (tacho) connection monitors fan speed and helps in system fault diagnosis. Power consumption and fan noise can be further reduced with the use of a PWM (pulse width modulation) controller such as the Sanyo Denki 9PC8666X, advised EAO.
The fans’ construction includes dual ball bearings and use Humiseal PCB moisture protection, and have a predicted lifespan 1.5% greater than their predecessors. The 25mm thick variants have a rated life of 60,000 hours (approximately seven years) at 60°C or 90,000 hours (approximately 10 years) at 40°C.
The fans are available with and without mounting ribs to meet a range of cooling and ventilation scenarios.
