My Tektronix 2445 'scope that I got 3 years ago has a fan whose
speed varies.  What is also a neat benefit is that it makes it
easier to maintain a semblance of *constant* rather than some
arbitrarily low temperature.  Quite a good thing for analog things
that drift in calibration with respect to temperature.  That scope
has taken some remarkably rough treatment and stays quite stable.

I agree; Apple should have learned about fans in, say about 1979 or
so.  I've replaced more Apple power packs in machines here than I
like to think about.  You'd at least think they could have put some
ventillation slots in those chintzy Apple ][ power packs.  I
suppose their lawyers advised them to seal the power pack to
prevent some kid from probing it with a paperclip or whatever.
Those Kensington System saver aftermarket fans help some, but
there still isn't any air circulation inside the power pack.
