iCoolFAN4
PiCoolFAN4 is an Advanced Active Cooling System especially designed for the Raspberry Pi4® for ease of use independent and autonomous cooling system. However it can also be used with all the former models of Raspberry Pi®. The PiCoolFAN4 provides an enhanced cooling capability based on embedded FAN and external temperature sensor. The used temperature sensor is placed exactly 3.5 mm above the Raspberry Pi 4 CPU. This guarantee accuracy and continuity of measuring of the system temperate as also close to the CPU environment. The PiCoolFAN4 does not need any software installation. In case of hardware, only an extremely simple FAN mechanical mounting process is needed. Thus make it very easy and useful for any application.
When the user need to have a very accurate temperature control and more advanced features, PiCoolFAN4 can be used also with provided Daemon. The Daemon reads the exact Raspberry Pi® CPU temperature. Write it via I2C to PiCoolFAN4 via I2C adjusting the FAN speed exactly to the Raspberry Pi® CPU temperature. The PiCoolFAN4 is not using any GPIO pins, and all communication with Raspberry Pi® is done only via I2C. The PiCoolFAN4 is compatible with heat-sink. With an additional 8mm header, if used, the user can have benefits of double cooling system – passive and active – working together.
The driver for the FAN is PWM controlled, and allows user, to set the FAN speed depending of the temperature, dramatically decreasing the possible noise generation to absolute minimum. Due to special PCB construction – thanks to theAir Circulation Technology– the injected by FAN air bounces of the CPU, and by absorbing its heat, escapes through special circle shaped openings above. This design guarantees proper air circulation and maximizes the cooling efficiency even in a low FAN speeds (very low noise generation). The PiCoolFAN4 FAN speed is adjusted automatically to temperature threshold.
The PiCoolFAN4 is standard equipped with:
– Battery Backed Hardware RTC DS1307 (coin battery 1220 optionally ordered),
– 2 user LEDs (RED and Green),
– 3 System LEDs (Cold, Hot, FAN – running)
– ESD Protected 1-wire interface (5/3V),
– Infra-Red Receiver interface,
and optionally:
– with High Current Relay Kit,
– and programmable sounder.
PiCoolFAN4 has embedded temperature sensor and Ιnfra-Red Receiver and there is no need to install software. For these reasons, the user can easily adopt PiCoolFAN4 to a Media Player like KODI.
