s/strongly suspect/definitely know/ ;-)

Reason being that my machine suddenly dropped dead (2 or 3 times maybe),
and when I then reactivated it, the fan made a nice tick....tick....tick noise
as if it tried to start but something blocked it a bit too much.
Shook and rocked the box a bit (not too difficult with a netbook after all ;),
then it worked again and ever since.
Probably a slightly wonky fan, but I'm not sure whether I should care
all that much at the moment.
I _am_ using the shell script currently, but within pretty safe limits
(I'd hope that I'm not insane after all), thus I don't think this negatively
affected fan health or machine.

I cannot really testify that those had been "properly triggered"
emergency shutdowns, but from the looks of it they definitely were,
nothing melted or smoking or whatever.

BIOS v0.3109 (ooold)
