Regardless of the advertising hype, making electrical connections with the
power on is always risking. Take the time to turn it off and do it right.
Why gamble?

Great advice. Plugging a 12v fan in with the power on "probably" wouldn't
hurt anything, but just a spike from anything that you may bump against
inside the case could cause damage. I have been working on electronics since
the military in the late '60s and if you can do it with the power off, do
it.....

You could mess up a device connected to the same cable.
The original poster should have provided a reason for wanting to do
so.

Thanks all. I will kill the power before experimenting with fans.
if your careful it can be done

NO. Only "Hot Swap" designed harddrives can safely do that.

Agreed - I've just done it myself, to add an extra fan for the recent
95F weather here.
But there is still the small risk of putting a spike on the 12V line if you
fumble the connection.
_Most_ times, other circuits on that line will shrug it off. . .
