> It's a Gigabyte 770T series mobo. It uses the it8720 chip. You can try writing directly to the pwm control inputs under the platform device node (i.e. /sys/devices/platform/it87.xxx/pwm*); these usually take 8-bit (0-255) values.
E.g. to set pwm1 to a value of 127 you just do echo 127 >/sys/devices/platform/it87.xxx/pwm1 You should take a look at the it87 driver source to find out what the various parameters mean. Note that I don't have a board with a modern it87 chip (i.e. one which can do fan PWM control) at hand, so the device names might be different; these were taken from a board using a Winbond w83627dhg chip. Also, if you wish to control the fans manually you should probably turn off any kind of automatic fan control in the BIOS. andrea
