I never thought of the carpet!  The whole whole is carpeted, all older 
but in decent condition.  Regularly vacuumed but....  OK, another 
mystery solved!

That gets changed about once a month.

Thanks!  I had another issue where the system started shutting down 
'randomly'.  No revving of fans (CPU and an added chassis fan are PWM); 
no revving fans sounds before.  Minimal dust collected at the PSU, 
unlike before.  Did find a collection on the fins of the CPU's heat sink
so air dusted that out -- made sure to wait until the components were 
around room temperature before and after.  Have seen and barely heard 
some  changes in the fan speeds.  CPU's fan rated 800-3000 RPM, PSensor 
says around 2500 RPM, CPU (socket) at 102øF (I knowwww: 41øC sounds cool
to me!).
