Normally, the CPU fan of my HP Tower PC just functions pretty
noiselessly and only speeds up in exceptional cases. Suddenly, since
this morning's start up, it immediately switches to high speed with an
increased level of noise as a result.
So, what might be the problem? I opened the case and controlled if any
amount of dust was present but that seems not to be the case.
I suppose there must be a sensor controlling the temperature. Could that
be broken?
I am using CPUID Hardware Monitor, and I am concerned about the
Temperature 1 value; is that normal?:
Hardware monitor Fintek F8000
Voltage 0 1.67 Volts [0xD1] (VIN0)
Voltage 1 1.66 Volts [0xCF] (VIN1)
Voltage 2 1.63 Volts [0xCC] (VIN2)
Fan 0 4587 RPM [0x147] (FANIN0)
Fan 1 2521 RPM [0x253] (FANIN1)
The four core temperatures however, are all around 31 degrees Celsius.
Any idea is welcome. Thanks in advance.
I am switching off for the remainder of the day though and shall be back
tomorrow.
Thomas

About a year or so ago, I was having temperature problems with my
laptop. (There was a broken fan blade which was jamming the fan.)
TThrottle helped me, keep the temperatures reasonable, until I found
out the problem and get it fixed.

My previous PC had the problem of a very noisy CPU fan. If room temperature
was anything above chill, it would make the fan go wild.
A technician on a shop suggested I check the computer's BIOS settings.
There was some setting along the lines of "try to keep the CPU always
at a temperature less than X" that was turned off. When I turned it on,
the CPU fan went amazingly quiet. I monitored the CPU temperatures, and
they never went up even when I couldn't even hear the CPU fan almost at
all. Only when the weather was really hot it would speed up.
(My new PC has a similar setting, but it was on from the get-go.)
I don't know, however, if this would be the the case in your situation,
especially given that it just happened suddenly, after having worked ok
in the past.
I don't know if, for instance, some Windows update or something like that
could mess up with the BIOS or other hardware settings. (Was there
something like a system update, or something similar, just previous to
the appearance of the problem?)
But check your BIOS settings just in case. There might also be a similar
setting somewhere in your OS (especially if some hardware control software
was installed alongside your motherboard/cpu.)

Thanks Stephen!
This is just what I need. Here in Sunny South Africa I can't render when
it's hot unless I set Pov-Ray to use only 2 or 3 cores.
Hmm BOINC. How about someone doing a BOINC patch for Pov-Ray? =D
That would be awesome!
Getting a little off off-topic here :)

Ditto here, I think the battery was duff because if I unplugged the
machine the settings would go back to default (including setting the fan
to 100% all the time).

Thanks Warp, I am going to investigate the possibilities you mention.
In the mean time, this morning, it started up ok, without problems, and
all temperatures are at normal levels. I really wonder what might have
happened.
Latest Windows update was on wednesday; the problem on sunday. I don't
think that would be related. Room temperatures are around 20 degrees and
even lower at day's start up, so that seems to be ruled out too.
It might have been a small piece of dust stuck on a vital part that sent
temperatures soaring up to 99 degrees (and that is now totally burned
up). Puzzling.
I'll keep my eyes open.

Thanks Stephen. I shall look at TThrottle in any case. This morning the
machine behaved like it should so I am wondering what happened. It
probably needed its Sunday Rest. I am again thinking that maybe a piece
of dust was stuck at the wrong place and needed to be burned down. The
fan is whole and rotating correctly.

rely on the duty cycle to throttle PovRay. When in hot countries.

Yeh!Show me a Pover that has spare CPU ticks to give to someone else. ;-)

It used to be a "hanging offence" at one time. ;-)

It is worth having a look at. It will log your core temperatures and CPU usage
for at least 12 hours. Then send you an email if they go over a limit, if you
want. I see that there is a newer version out, I should give it a look over.

It might have been a core stuck in a loop and it just needed a re-boot. You
never can tell.

Good and PC fans are easier to change.

Indeed. They should do what they are told though ;-)

Not sure about controlling fan speed. It seems to happen automatically
in situations where external temp (for instance) is high. I shall have a
look at speedfan too. Thanks!
