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.
