That's exactly how the machine was run for many months. FreeBSD was
added only recently to this machine. I usally start 2 seti sessions when
I'm done for the day on this machine. Under Linux it never..ever reached
even 100F.(still the same) That's whats so baffling about this.(I only
overclocked it very recently out of curiosity)
Tommorow I am going to run the programs Peter suggested. On the sessions
between Linux and FreeBSD I usually shut it off for a moment the
temperatures took a while to stabilize it was not immediately cool as
someone questioned.

I want to stress it again this is only with the SMP kernel. The standard
kernels do indeed run cool.
