That would only be the case if there is some bigger fault at play, such
as having a 5V fan wired to 12V. I'm not aware of any PC-grade fan that
would be capable of running beyond its design limits in normal use.

More likely is that the fan is thermally controlled, but on halt the
control is being set to full speed which might be annoying but is not a
problem for the fan per se.

I suspect that you're just not accustomed to hearing the fan run at full
speed. Some can be very noisy, not to mention irritating - like the one
in my laptop.
