CPU Heat?

[Jethro]

C = (F - 32) * 5 / 9.

Thanks

But I knew that. I was wondering what 'temp1' was and whether it was
the CPU. I didn't ask the question right. Sorry. Old age syndrome.

Not that I've heard of.

I don't see where Speedfan will shut my machine down at a threshold,
Did I miss it?

Configure -> Events. Define an event that checks if a temperature
exceeds some threshold. Define its action to "execute" and have it run
the shutdown.exe program (use /? to see its parameters). However, your
BIOS should already provide an auto-shutdown function; i.e., you set the
threshold temperature and the BIOS will power down the system (since any
software that detects over temperatures and then performs a good
shutdown of Windows will probably be too long to protect the hardware,
unless you set the software's threshold much lower than the critical
power-down temperature in the BIOS).

OhOh

Speedfan says temp1 is on fire at 130F.

Hardly. It depends on WHICH brand and model of CPU that you have that
you never mentioned. The AMD Athlons go to 80C (some to 85C) for their
maximum *working* temperature but most users like to keep them under
60C.

80C = 176F
60C = 140F

So your CPU is just fine for temperature - but remember that if 60C is
its idle temperature that it will get hotter when playing games or
running anything that heavily exercises the CPU. I have SpeedFan
configured to up the CPU fan speed (for AMD Athlon XP 3200+) at 55C and
warn when it gets to 60C. In the BIOS, I have it power down at 75C.
Because of the BIOS-controlled thermal protection, I don't bother
defining events in Speedfan to run programs to shutdown the OS (I
haven't run into corruption problems because Windows XP wasn't shutdown
properly, and I do data backups).

At 130F (54.4C), that isn't your case temperature. Case temperature is
probably much lower, like between 20C to 45C depending on how good is
airflow, how noisy are all the fans, what is producing heat, efficieny
rating of the PSU (which equates into how much heat it produces), number
of memory sticks, drives, daughercards, high-end video card, etc.

Could be you need a better HSF (heatsink + fan) on your CPU. The stock
unit is okay but not if you overclock or run heavy CPU programs all the
time. I overclock my Athlon XP Barton 2500+ to be a 3200+ by upping the
FSB to 200MHz (which the memory sticks support) so it produces more
heat. So I put on a Thermalright HSF. I also lapped the heatsink to
make a very flat and shiny surface to mate to the CPU and used better
thermal paste (not ArticSilver but 2nd to it), but most users never go
that far. Unfortunatly most end users glop way too much thermal paste
on the heatsink. Thermal paste has a higher thermal transfer rate than
air but is nowhere close to metal-to-metal contact. It should be
applied thinly so it is translucent to fill in the microscopic air gaps
in the surfaces that will never perfectly mate together. It is not used
as the only transfer medium so don't use it to compensate for a warped
heatsink or think it should be globbed on in mass. Put on a translucent
layer, twist the heatsink onto the CPU, and then affix using the clips.
Although end users jobbing up their own computers are usually the boobs
that screw up by putting on way too much thermal paste, I've seen
computer shops do it, too.

I have a ASUS P4B533-VM MOBO, and don't see any mention of temperature
monitoring. Fan speed either.

page 90 of manual

 

[darklight]

Thanks

I downloaded MBM and installed it. So far I don't see that it will
shut my machine down if temp reaches a temperature level - nor do I
see a place to set that to be done. Am I missing it?

Jethro

have you read page 101 of your manual?

Hmm

My manual's pages are chapter # - page #. No page # is as high as
101. I do see page 4-30 however - now anyway.

Thanks

mind you i did download your manual

 

[Davy]

I alway's thought CPUs (or some at least) had a over temperature
sensor built in them so you get shut down to prevent thermal damage.

There should'nt be any cause for concern if you are not overclocking
and using the correct fan and heatsink. There's no software I know
off, but that ain't saying there is'nt any.

Why not drop a post in CPU section..? Here's the link

Oh - my manual came with the MOBO, pre-printed. So maybe the on-line
manual is different huh? I'll have to take a look.

Thanks

Intel CPUs have internal temperature-protection systems that monitor
heat. If an Intel CPU begins to overheat it will shut itself down.

As far as I know AMD CPUs do not have this protection. (The company
may have added it to its newer socket 939s, but I have not heard about
it.) AMD chips will cook themselves to death if they start to
overheat.

This is different from the circuitry that detects the CPU fan. Current
CPUs will not run unless the heatsink is properly mounted. However,
AMD CPUs will still power up without a heatsink fan (learned that one
the hard way; if it's too quiet, beware!).

Motherboard Monitor or Speedfan might prove useful... but I no longer
use either one. I keep my systems cool with good airflow and frequent
cleaning.

 

[anniewarbucks]

You do not need to worry about the heat on the CPU. About the only
thing you do have to worry about is keeping the fans inside the case
running. Your power supply fan should keep the top cool the heatsik
fan should keep the proccessor cool and some computers also have a
case fan to disapate heat effectively. You might though pop open your
case and place a drop of a very fine oil on the bearings of your fans
and vacuum the dust out of your case. This realy should be done at
least twice a year.

Interesting.

I just vacuumed and otherwise cleaned the insides before I close up
the case. Let's see what the AM brings.

They do now.

You need to get out more.

Not anymore.

Current CPUs will not run unless the heatsink is properly mounted.

That is overstated,

However, AMD CPUs will still power up without a heatsink fan
(learned that one the hard way; if it's too quiet, beware!).

The world's moved on on that.

but I no longer use either one. I keep my systems cool

Wont help if the fan fails.

.... will throttle itself slower, in some cases. This is
almost unfortunate as many people then wonder if they have a
virus or somesuch, it leaves them spending a lot of time
wondering. Even so, I would rather have a CPU slow down IF
it remains stable the entire time (If the threshold is set
low enough that no errors were occuring from overheating
yet) rather than whole system/operations terminated
abruptly.

As far as I know AMD CPUs do not have this protection. (The company
may have added it to its newer socket 939s, but I have not heard about
it.) AMD chips will cook themselves to death if they start to
overheat.

False. The motherboard shuts it down, this is a feature on
all boards adhering to AMD's specs, meaning any properly
designed board you'd want to use will do so, only some
generic counterfeit might not.

This is different from the circuitry that detects the CPU fan. Current
CPUs will not run unless the heatsink is properly mounted. However,
AMD CPUs will still power up without a heatsink fan (learned that one
the hard way; if it's too quiet, beware!).

Nonsense. There is no distinction between AMD and Intel
CPUs when it comes to heatsink fan. Any settings relating
to fan shutdown are chosen by the motherboard manufacturer
independent of which CPU is used.

Motherboard Monitor or Speedfan might prove useful... but I no longer
use either one. I keep my systems cool with good airflow and frequent
cleaning.

What would prove useful is for you to buy more hardware and
check these things yourself so you see it isn't an issue.

Fans that need oil (sleeve bearing type only) should have
medium to heavy oil added, never "very fine" oil.
If you took a fan that works fine and added very fine oil,
you can even make it worse than if you didn't add the oil.
Adding light oil should only be seen as an emergency measure
if there wasn't anything else available (stranded on an
island?) and your fan was chewing up the bearing. The
resolution then would be to relube with thicker oil as soon
as possible.

The first form is the correct one |-)

Actually, the second is grammatically correct, though its use is
archaic. Most of us would say: "It's me" instead of "It is I," even
though the latter is grammatically correct.

 

[Rod Speed]

Irrelevant to his MORE CORRECTLY.

Most of us would say: "It's me" instead of "It is I,"
even though the latter is grammatically correct.

Different matter entirely to the sentence he actually used.

'Me' is the object of a verb. 'I' is the subject.
