The PiCoolFan is an Advanced Cooling Fan System for the RaspberryPi®, one that offers total temperature control over the RaspberryPi®. It is addressed to all RaspberryPi® users whose board reaches a high temperature, for whatever reason.
There is no need for any additional cabling or Power Supply, as the PiCoolFan is powered by the same Power Supply of your original RaspberryPi® board; just insert the PiCoolFan controller on top of the P1 connector of your RaspberryPi®. The PiCoolFan is equipped with an embedded temperature measurement system that continuously checks the RaspberryPi® PCB temperature with a dedicated sensor, and according to the measured temperature, the PiCoolFan micro controller starts, stops, or regulates the rotational speed of the embedded micro-fan. Thanks to the Air Distribution Plate, the PiCoolFan cools not only the microprocessor on the RaspberryPi® board but all the heat-generating devices, as well as the whole RaspberryPi® PCB. The embedded microcontroller is easily accessible by the user trough the I2C PiCO interface and allows reading of the measured temperature, setting of temperature threshold, as well as starting/stopping the embedded micro fan. In addition the PiCoolFan offers on the same PCB a battery backed RTC and Real Time Powering Voltage Monitoring.
