Hello Dann,
I had this very same problem on my Satellite 2505CDS and 2515CDS and
someone was kind enough to port the Linux fan util to FreeBSD so it
works great ;)
I have attached the fan util and here are some instructions on how to
use it. It *may* need to be modified slightly for a new laptop but I'm
not sure (not being a coder myself).
To start run: fan -n
to stop: fan -f (both must be done as root)
HTH
