I've tried to follow the directions on this thread: How to control fan speed?

But at the end of the day, pwmconfig gives me this error:

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

Is there anything I can still do to control my cpu fan speed?

I have the same machine so here the output of the request:

As it seems your computer (is it a Mac?) has not got any controllable fans. You can try to run

sudo pwmconfig

another time and try to answer all Did you see/hear a fan stopping during the above test (n)? with yes.

Also, it would be helpful for me if you give us the output of
