There's something wrong with my PC, and I don't know what to do about it.
The CPU fan is really, really, really picky about the room temperature.
At something like 20-22 degrees celsius it's really content, and spins at
a moderately silent 2500-2700 RPM.
Elevate the room temperature just by a few degrees, to something like 24
or 25 celsius, and the CPU fan immediately jumps to at least 3000 RPM, even
when the CPU is completely idle, and starts being annoying audible.
A few degrees more, to something like 27-28 celsius, and the CPU fan goes
completely crazy, reaching speeds even exceeding 4000 RPM, which sounds like
a jet taking off. I'm afraid of keeping my PC running in this situation.
At this moment the room temperature is 31 degrees celsius, the computer
case is open, the case fan is rotating at full speed (I have a case fan with
three speed settings), and I have a regular electric fan blowing air directly
inside the computer at full speed, yet the CPU fan is running at 3900 RPM,
even though the CPU is completely idle. I wouldn't even dare to try what it
does in a *normal* situation.
In none of these situations does the actual CPU temperature exceed 50
degrees celsius. For example at this very moment it's 44 degrees. Yet the
CPU fan is going at 3900 RPM. I'm afraid of keeping the PC on for much
longer because it sounds like it's going to break at any moment.
This isn't normal. A friend's PC runs almost silent even at these high
room temperatures. My Xbox360 runs very silently.
I have no idea what the problem could be. Any suggestions? I can't use my
PC because I'm afraid it will break.

The fan/BIOS is probably designed to run "silently" at CPU-idle and only
speed up once it gets loaded. They are probably doing this by triggering at
speed trigger temperatures?
Anyway, those temps and fan speeds seem completely normal to me (on my older
PC the CPU fan runs at 5000 rpm the whole time). What CPU temp do you get
at full load?
You can buy a quieter fan if it's just the noise that's a problem.

I would imagine the fan bearings are worn out. That's usually the cause
of excessive fan noice.
The good news (??!) is that if the fan does in fact stop spinning, the
PC should turn itself off before your CPU fries.

Not necessarily. If the fan just sounds like a jet engine, it's probably
just a small fan spinning relatively fast. You may be able to get a
quieter fan, or if your case has a spot for it, a larger fan.

Yup. Thank goodness for automatic thermal shutdown.
Heh. The other day my wife's computer (a notebook) shut down
automatically, and she couldn't get it to come on again. I picked it up,
and noticed two things immediately. The bottom was scorching hot, and a
receipt flitted away as I picked up the computer.
Yeah, a receipt blocked the fan's input port. What really worried me was
the fact that the computer had gotten so hot that even the pins on the
VGA connector were too hot to touch! Scary... no permanent damage that I
can determine was done to the computer.

Some years ago it happened to my (old) Dell laptop. The fans started going
at full speed when they shouldn't have and the CPU slowed down for no good
reason. After some googling I found that someone had developed an utility to
control the fans manually and it worked perfectly. This utility is only for
Precision/Dell laptops (http://www.diefer.de/i8kfan/ ) but possibly
something like it exists for other brands.

I use the free program Speedfan.

Get a Zalman cooler, run it at lowest fan speed settings and enjoy a silent
computer that doesn't over heat.

From the way Warp phrased it, I got the impression that this PC *was*
working fine, and now it's suddenly started doing this.
Usual reason for that is worn out bearings.

I tried to install Linux on my dad's laptop, and had an interesting
experience. The installer kept crashing at random points with random
error messages. Tried several times and it just wouldn't work. Then I
noticed that the underside of the machine was scalding hot. The fan
wasn't spinning at all. We assumed it was broken.
Then we rebooted the laptop, and immediately the fan started spinning
like crazy. I left it on the BIOS screen, and the fan's spinning away,
and I'm watching the temperature stats. Eventually the fan starts to
slow down, and eventually it completely stops spinning.
So I load up the Linux installer and start again. Same deal. Eventually
it crashes, and the laptop is once again burning hot, with no fan activity.
So I reboot it, and the fan starts spinning like crazy. I immediately go
back into the Linux installer, and start installing. Here's the thing -
the fan stays spinning at maximum speed, even long after the laptop is
stone cold.
Yes, that's right. THE FAN IS CONTROLLED IN SOFTWARE! How retarded is
that? Surely this is a serious fire hazard...
Still, it was a very old laptop. (Actually, it still is.)
