Living near the home of WD40, I would like to point
out that while it is an excellent penetrant, it is a
lousy lubricant.  A drop of 10W30 motor oil is a much
better lube.  And just partially peel off the cover label.

If everything else is quiet, one might hear varying load
on the switching power supply as the processor utilization
changes.
