913,How to lower the speed of the fans ? (Examined/Solved - I should reboot to find out!),contact,somebody,"On Windows there is a great little freeware called Fanspeed (almico.com), which

allows the user to change the speed of the fans connected to the motherboard.

Will you implement this function or should I or someone else who has the skills

try to code this? Maybe it is not really related to your code?

I wrote to the creator of Fanspeed: he answered that he doesn't plan to port his

program to Linux. Neither does he intend to open source it.

Thank you for your attention and great work!

we don't have such a program. I've often thought of writing one.

One downside is that if it goes bad you could damage someone's PC

so you have to be careful.



The way I'd do it is:

- search /proc/sys/dev/sensors/* for pwm* and fan* entries;

- bind a pwmX to fanY by asking the user or by adjusting pwmX and

  searching all fans for one that changes;

- bind tempZ to pwmX/fanY by asking the user

- run as a daemon, querying tempZ, fanY, and adjusting pwmX.



We need to do a better job of standardizing the PWM interface in /proc;

the drivers have some differences now.
