Got ya beat Brad. 1949-????, 65 years so far, and still counting. As a
friend says, beating the odds every day. ;-)

I have tended to look at that strap as a way to get
executed/electrocuted, but you can bet the whole farm that I have a hand
ON the chassis of anything I am also about to be touching chips in.

I would suggest that A, not a strong enough blast of air was used, and
B, that the fans bearings were damaged by overspeeding from the air
stream. The fire siren whine as it spools up to 10x its normal running
speed is a cool sound, but to be avoided, I usually put a finger on the
hub & only let it turn a turn or two. I regularly clean with compressed
air, but both of my compressors can make better than 100 psi. And I have
never had a PSU go south that I can connect with a good D&C. YMMV of
course.
