I don't know of any such thing. Furthermore, I don't know how you would
be able to generate such a thing without specifying far too much to make
it useful. "Normal conditions" includes things like:
-ambient temperature
-RAM
-HD (capacity, rpm)
-CPU
-surface the machine is resting on
-airflow across machine
-optical drive in use?

If you decide that you still want to do this thing, it's easy enough to
generate the sort of comparison you want: do something to generate a
full CPU load, and take note of how long it takes _your_ machine to turn
on the fan. Report back to us with your CPU load, the time to fan on,
details of your machine, and the local conditions. Someone here with a
similar configuration might agree to duplicate your test, or simply be
able to tell you whether or not your machine is "in the ballpark."


For what it's worth, I'd think it unusual for a hardware problem to
cause the fan to turn on early or late instead of simply not to turn on
at all. If you suspect software problems, then I'd think that you'd
notice other symptoms (though I'm no expert).

Do you have a reason to suspect a problem with your machine?
