G4FanControl | useful application which enables you to program

G4FanControl is a C library typically used in Internet of Things (IoT), Raspberry Pi applications. G4FanControl has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

G4FanControl is a software I've developed more or less 10 years ago, when I faced overheating problems with my old PowerBook G4. I sold it for some years and now I decided to make it free and opensource. The code is available on GitHub. As anyone who has put their hands on this wonderful laptop can confirm, the operating temperatures quickly climb and it soon becomes practically impossible to touch, especially on the bottom under the display. What makes this situation truly crazy is that this laptop actually has two powerful FANs which are not used at all by the operating system, probably to save battery power. This utility enables you to manually program the hardware fan controller of your iBook/PowerBook G4 laptop, increasing the temperature threshold and the fan RPM. The G4 Powerbook and IBook cooling system is managed by the ADT7467 controller from Analog Devices. The ADT7467 chip has one integrated temperature sensor (Local Sensor) and two more remote sensors and everything can be controlled using a convenient I2C interface.
