Hi Ian,

I am a member or the I2C & LM Sensors development team. We recently
heard about your Varyfan project. Since it is closely related to our
project, I'd like to discuss with you about some points.

How live is your project? Are you still working on it?

How does it compare with our own PWM programs? See here:
http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/prog/pwm/pwmconfig
http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/prog/pwm/fancontrol

We have a "useful links" page and could add a link to your page there if
you think that your project is of general interest for our users.

Thanks!

I'm no longer working on this project, and I was only developer.  (Want
to take it over?). I now have a quiet PC that doesn't require the
software to keep the noise down.  And anyway, I'm using kernel 2.6-test,
which isn't yet supported by the sensors package.  I was thinking that I
should put a note on the web page about it now being abandonware.

There were user-interface things on my wishlist (Qt, scrolling graph,
etc.), but basically, the only functional improvement would be in the
equation.

Pretty much the only advantage would be the fact that varyfan is written
in C, it would have a smaller footprint, and wouldn't need to execute
other programs every cycle.  The equation to propose a new fan speed is
different (mine is linear, yours looks like it might better fit the
speed vs airflow curve).

When I started the project, I couldn't find a Linux version of the
Speedfan program.  Now you've got an actively maintained program and
I've got a more or less abandoned one, it might be best not to bother. 
Of course, if you still think it might be interesting to others, go for
it.

Thanks for the interest.

Yes, I do think so. Link added. Maybe someday someone will be interested
in taking over maintenership and improve your program, who knows.

You're welcome.
