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)
Temperature 0 27°C (80°F) [0x1B] (TMPIN0)
Temperature 1 99°C (210°F) [0x63] (TMPIN1)
Temperature 2 23°C (73°F) [0x17] (TMPIN2)
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.

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.

It is a nice bit of software even if you don’t use the Boinc feature. I used to
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 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.
If you fan’s speed can be controlled then you might want to look at speedfan.

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!

You can get task manager to show the CPU usage for each core
(Performance -> View -> CPU History -> One Graph Per CPU), it should
then be obvious if any of the cores are stuck in a loop.

I did not mean it literally. :-)
One of the irritations with my current, i7 laptop, is. Regularly the system'
process will use 13% ~ 25% of the recourses and the machine will be very
sluggish. But you never see a core maxed out.
You do with PovRay, though. :-)

Of course. I forgot to check that yesterday. Stupid. ;-)

My i7 PC does that too sometimes. It seems to have to do with some
arcane Windows process... I checked with the task manager and one or
another process was active.

I don’t know if it would be that useful to you. Having just read the
instructions, it looks like it would be suitable for slowing down noisy fans.

Btw, did you check that something wasn't consuming CPU time? Was the CPU
at 100% load?

Arcane indeed.
I downloaded Process Explorer to see if I could find out what was
causing it. Cyber-man's magic. Whooo! :-)

IIRC, he said that the temperatures of cores were fine (and low) when
the incident happened. Of course, if it was at start-up of the computer,
they hadn't had the time to heat yet. (I guess they have that big
inertia of a block of alu-copper attached to them, something the other
chip might not have)

Well, that I forgot to check indeed. But I am pretty sure it was not the
case. The system was neither slowed down at all.
@ Le_Forgeron: the temperatures of the cores remained low the whole day.
Only the TMPIN1 of the motherboard showed an abnormal temperature of 99,
according to the CPUID Harware Monitor.

svchost, SearchIndexer, taskmgr, are some of the arcanes (to me)
although normally they do not take up much cpu time.

Of course they were because the fan was spinning so fast. It doesn't
mean the load wasn't at 100%.

The CPU load being high doen't necessarily mean that the system becomes
sluggish.

True indeed. However, what set off the fan seems to have been the
extreme high temperature (99C) somewhere on the motherboard. Related to
a core? I don't know. I do not pretend to understand the works ;-)
There is a huge lot of confusion on the web about what TEMPIN0, TEMPIN1
and TEMPIN2 are referring to. Nobody seems really to know. So, examples
given, some say:
TEMPIN0=System Temp
TEMPIN1=North Bridge
TEMPIN2=South Bridge
others guess:
TMPIN0 = SYS
TMPIN1 = CPU
TMPIN2 = MCH
and others, comparing HWMonitor with Everest Ultimate come to:
BIOS - HWMonitor - Everest
SYS = TMPIN0 = Motherboard
CPU = TMPIN1 = CPU
MCH = TMPIN2 = Northbridge
I cannot bake any bread from that :-(

Which leads of course to the expected question of 2.50 Martian Dollars:
/where/ is that manual? I have none; I cannot find anything on the web
resembling docs.
