What's a safe temperature to run the CPU?

[PA20Pilot]

Hi,

My alarm sounds every now and then when things get real busy, like
rendering 3D models, but I may have my temp limits set wrong. What upper
limit would be considered within normal opperating expectations.

Thanks!

Go to your processor mftr.'s website - it will be either AMD or Intel -
and look up the specs of your particular processor. The temperature
tolerances will be shown there.

There is no standard answer to this.
Not only does it depend upon who made your processor but also the model of
processor you are using.

But bear in mind that the specifications generally refer to die
temperature - the temperature of the actual silicon chip. Newer chips
have on-chip temperature sensing diodes, which give a good
approximation to the die temperature, but many MoBos still sense the
temperature measured by a sensor behind the CPU socket, which will
generally indicate a temperature significantly lower than the real die
temperature.

Please respond to the Newsgroup, so that others may benefit from the exchange.

Hi,

You've all raised some good points, I'll look into them and see what's
up with things.

CPU type is an AMD Athlon XP-A, 1833 Mhz (5.5 x 333) 2500+
MoBo MSI K7N2 Delta-L (MS-6570G)

If I learn anything not too specific to my hardware I'll come back and
slap it here.

Thanks again for the help!

That was too easy.

System Operating Temperatures Will Vary

The operating temperature of a system or processor is highly dependent
on the characteristics of the system as a whole and the combination of
components that make up the system. Consequently, the "normal" operating
temperature will vary from system to system, depending on each system's
make-up. Some of the variables that affect the operating temperature of
a system are: case size, air flow characteristics, installed components,
processor speed, processor heatsink/fan solution, thermal interface
material, power supply, voltage settings, workload, and ambient air
temperature.

Although "normal" operating temperatures are not specified for AMD
processors, there are maximum operating temperature ratings that must
not be exceeded. The maximum operating temperature of a processor may be
determined by the processor's Ordering Part Number (OPN). Refer to the
processor's data sheet for additional information (data sheets may be
downloaded from the Technical Documents page). Typically, the maximum
operating temperatures for Socket A AMD Athlon™ and AMD Duron™ desktop
processors are 90 degrees Celsius for processors operating up to 1GHz,
and 95 degrees Celsius for processors operating above 1GHz.

Note: The maximum operating temperature specification is based on a
measurement taken directly from the top center of the processor die. The
temperature reported by a system's BIOS may not reflect the true
temperature of the processor if the measurement is taken from an
alternative location. Additionally, the reported temperature will be
affected by the accuracy of the thermal probe, hardware monitor, and
analog to digital signal conversion. As a result, some variance should
be allowed when comparing the maximum operating temperature to the
temperature reported by the system's BIOS.

90 degrees celsius would be hot hot hot
The higher the operating temp the shorter the life of the chip.
Normal operating temp for that Barton 11x166 would be more in the range of
38-50 degrees
at least thats what mine used to run at and still does

The max die temp might be 90 or 95C but as you mentioned it is the die temp
not the one measured. If you go thru some more of the AMD material and the
heatsink information, you may end up concluding that those temp relates to
something around 70 degree C as measured. (an estimate).

Thus, I would never want a measured temp much over 60 degree C. Personally,
I like mine in the 40-50 degree range or better but quite a few of the
heatsink fan combination on purchased system would end up above 50 degrees.
