John,

If you blow down the inside of the computer with compressed air, put 
a finger on
the fan on the CPU.  You don't want it to turn.  The compressed air can spin up
the fan a lot faster than it is supposed to run.  So a DC motor being turned
externally becomes a generator, and spinning faster then design speed causes it
to output a higher voltage than it runs on.  This overvoltage is 
being applied back
to the mother board and can back feed the CPU and cause it to fail.

John
