case fans control?

hi,
Is it possible to control case fans (by changing pwm) under linux?

e.g. I have Zyxel 310 Nas and i can change fan speed by put number between 0-255 to specific file, like

echo 180 > /sys/class/i2c-adapter/i2c-0/0-002e/pwm1

I want to write a bash script to control fans in dependence on actual temperature. e.g. Turn on a side fan when temperature on graphics card goes over 60*C. Or turn off all case fans when my PC is on idle - just powered on.

So i will be very happy if i can do some similar as at my zyxel. My mobo is Asrock Extreme4 970.
