Adds the same fan and temperature cooling functions to our CFA631, CFA635 and CFA735 intelligent USB displays that are available natively in CFA633 displays.

  • Four fan connectors with RPM monitoring and variable PWM fan power control
    NOTE: Not recommended for use with 4-Wire fans
  • Temperature Monitoring: up to 32 channels (16 channels on the CFA-FBSCAB) at up to 0.5°C accuracy
  • 4 GPIO lines on the System Cooling Accessory Boards allow:
    • ATX power supply control functionality. Use keypad buttons on the display as "power" and "reset" buttons for your system.
    • Hardware watchdog that can reset the host in the case of host software failure.
    • Advanced digital GPIO control with PWM output
  • Compatible with our free software for controlling all display functionality, including these temperature and fan features.
