Stef,

I have my laptop downloading updates, running a vm and installing clunky windows software therein.  The fan just started, so my reduced load theory seems to hold water.  Something in what has been done in the image and/or vm has allowed things that once would cause my laptop to heat up to run w/o need of the fan.  The fan *could* have quit, but that is now clearly not the case.  Pharo is getting better.
