  Socket 5 was the early Pentium socket.  Most Pentium fans hook onto tabs
that were added with Socket 7.

  The AMD DX5-133 is a clock-multiplied 486-class CPU, designed to run in
486 motherboards with a 33MHz bus speed.  [Intel's DX4 ran at 3x bus speed,
or 100MHz, so AMD's 4x was named "DX5".]

  So the fan you need is to fit a 486.  Note that some 486 models could get
by with a very modest heat sink, but the 4x multiplier is going to put this
CPU on the high end of 486 heat output, and so I'd insist on a fan.

  Most 486 fans (and heat sinks) I've seen were attached to the CPU with an
adhesive -- do you have a good way to remove the old one?
