I just can't stop screaming enough from that statement.
- there's 120 - 240 volts in the power supply.
Why is /that/ safe?
Because it is isolated inside a metal box, and without prying the box
open it's hard to electrocute yourself.
- mainframe and midi computers used 120v Boxer Fans all over.
I've never seen them 'zapping' anything, mostly because
they used higher quality wiring and connectors than today's 12v fans.
Use a pre-molded fan connector and there are no exposed connections anywhere.
They were also opened only by people who knew what they were doing.
(There are exceptions, like the one I know of who laid a metal tool
across some low-voltage rails on the backplane--in the days when these
rails really were rails--and fused the tool to the rails before the
power supply blew.)
On the other hand, only low voltage fans offer the
yellow tachometer wire to monitor them,
not that you're running any program that'll monitor and report that anyway.
It's hard to find software that will successfully find and monitor
fans and temperatures.
