SRF-FAN

The SRF-FAN is a CompactPCI® Serial peripheral card, equipped with an 80x80x25mm long life fan, positioned for lateral airflow. Developed for demanding applications, the SRF-FAN can be inserted into the adjacent backplane slot e.g. of a CPU card or GPU board, in order to improve the overall heat dissipation. The provided fan has been chosen for extreme expected life (180,000h @60°C) and high airflow. It can be operated either permanently at maximum airflow, or pulse width modulated, controlled via I2C. The fan is mounted to the PCB by special brackets for variable height positioning, thus minimizing the SRF-FAN board profile, and allowing optimized cooling of the targeted components. The SRF-FAN is scalable with respect to the maximum forced airflow, and for this purpose available with three different fans, from 1 to 2m3/min. The on-board PWM controller allows flexible configuration via the backplane I2C. The fan can be operated between 25-100% duty cycle, and its speed is permanently monitored.
