Who ya gonna call? Ghost Busters!

I don't have a suggestion, but I would note that it's
not always something racing that ramps up my fan.
We're having a heat wave lately. Sometimes it seems
to speed up just to catch up. Or I might just start a
program and that's enough to trigger it.

If it were me I'd check task scheduler and services to
make sure nothing unnecessary is set to run. Also check
Autoruns. For instance, if you use Everything.exe then do
you really need indexing enabled? I use Agent Ransack and
haven't enabled indexing for many years. Since
everything.exe has its own indexing, that seems like all
the more reason to turn off the indexing service.

In general, unless you have a lot of self-updating going
on, there's rarely any reason for things to start of their
own accord.
I don't think I have anything at all on XP or 7 that
runs without me starting it. (I guess AV scans would
do that, but I also don't have AV installed.) On XP
I've even disabled Task Scheduler, though 7 doesn't
seem to allow me to do that. I have to do wacky things
like schedule an unwanted task for 3 AM when I won't
have the computer on.
