you can change the fan speed with the generic program Speedfan.
I find 2 speeds. One inaudible, one quite loud.

Toshiba laptops , or this one at least, has the Power management icon
in control panel Replaced with a "toshiba power saver" icon.

You can set the Speed to "performance" or "battery optimised"
And the Cooling to "performance" or "battery optimised"

For speed,
That's fast or slow, respectively. (I find that slow yields the same
cpu temp, so no point for me! But maybe battery lasts longer with
it).

For cooling,
Performance is safest. The CPU fan goes audible/fast after it reaches
past 50 degrees.
At "battery optimised", the CPU fan still isn't on. I don't use that
setting. (At one point I wondered why the fan wasn't going on)

The CPU climbs up to 50 and idles around 50 maybe even up to 55 or
more if the fan didn't get to the fast speed.

Note: on my laptop, speed is under a setting called "intel speedstep
technology". My processor is a p4 mobile (not a P4M).
It's 1.9GHz. The intel processorfinder site shows it as low
wattage(so low power, not that much heat). Was < 30W. As oppose to
others that are about 80W. But i'd rather than fan didn't get audible
at all.
