Yes.  But of course, if the "fan never kicks in", then that is the
same thing as disabling the fan, correct?  Will the temperatures ever
get too high?  If not, then disabling the fan is safe.  But really
this is just speculation on my part, based on my surprise that my
little experiment seems to be working.

It seems to me that most of the time when the fan is running it is
doing so not because the laptop needs to be cooled internally, but to
maintain *externally* "safe" temperatures.  And my T61 does feel, at
times, much warmer externally but this does not seem to correlate with
the internal temperatures, which remain mostly steady.
