Project Description
Review this project Web Page Developer Dashboard

Automatic VGA fan duty cycle controller for a Linux system with Fintek F57373S or F57375S/SP sensor chips.

Some nvidia VGAs (ex. my Asus V9570 (Geforce FX 5700)) have F57373S as fan controller. If you have any trouble with controlling duty cycle (fan speed) with the nvclock, this program could be an alternative.

System Requirements

Hardware requirements:
VGA which has a sensor chip of Fintek F57373S or F57375S/SP.

Software prerequisites:
1a. You must install nvidia driver.
1b. You must enable both i2c_dev and f75375s modules in the /etc/modules before using this program.
2. If you install nvidia driver and enable those modules correctly, you can know device number and slave address by using sensors-detect command of lm-sensors tool.
