CPU temperature

[Angela]

What is the acceptable temperature range for a CPU? Is
49/50/51 degrees celsius ok?

[Pete Baker]

Hi Angela

Are you talking about a temp of 50 celsius when the CPU is idle or at peak
performance?

If idle I'd be concerned, your CPU temp is likely to rise another 10-20
degrees when under pressure and the cooling off will take longer as well....
as a peak it's fine.

Hope that helps

I "used" to be very worried about the CPU temps. I had 2 monitoring programs
on the computer. Had automatic alarms and shutdowns that were temperature
selectable.

I have thrown all of that crap out the window. If your computer runs, and
doesn't crash, there is nothing to worry about. Open the case and get rid of
the dust bunnies every 3-4 months. Use canned air and a small hand vac in
addition. Make sure the fans are spinning w/o any unnatural noise! If you
have suspected heat problems, remove the side of the case and blow a small
fan into the case. If the problem goes away, then you have something to
worry about!

The fact is, modern silicon is extremely rugged! Look at all the sensors and
microchips in a modern automobile engine. Did you ever open the hood of your
car on a hot August day, after driving for 15-20 miles. Why would one think
that a CPU would be any less rugged? The technology is the same!

And no, 45-55 Celsius is nothing to worry about! An auto engine compartment
is well over 100 Celsius under extreme conditions.

Oh! You say it shortens the CPU lifespan! Just how long are you going to
keep that computer that goes obsolete 4 months after you purchase it?

49C is120.2F and 51C is 123.8F that is kind of hot.

Each CPU has a different specification. Both Intel and AMD
have the temperature limits for each model on their
websites.

Look for "thermal limits"...

Many thanks I managed to track the info down on the AMP
website - normal is generally around 65 degrees, max 70 to
90 degrees dependindg on exact model. 50 degrees seems
well within this.

What a load of baloney! 49°C under load is /NOT/ hot!

[Chris Johnson]

I don't know what celsius means, but I do know that an average temp of
125-140f is moderate, heavy use would raise that somewhat.

There are limits!

It is certainly possible to spend too much time worring about CPU
temperature, but it is also possible to be too blase about it. Your
statement: "If your computer runs, and doesn't crash, there is nothing
to worry about." is rather akin to saying: "if your car runs and
doesn't make unusual noises, you don't need to worry about routine
maintenance", or even "If you feel well, you don't need to have any
routine health checks".

Your routine maintenance advice is good, but by the time overheating
has caused perceptible problems, it has probably already substantially
shortened the life of your CPU (which I might want to keep for 2-3
years and to pass on to someone with less need for raw performance in
his computer after that).

The chips that are used in cars are designed to be rugged and to
survive in that hostile environment. They don't have to be (and
aren't) very sophisticated. Chips used in personal computers are
designed for maximum performance in what should be a better-regulated
environment.

As someone else has said in this thread, a "good" CPU temperature
depends on the CPU (mainly Intel vs AMD) and what it is doing. The
surface temperature of a recent AMD chip _running_ _full_ _out_ is
likely to be around 55 degrees, or even a little higher, unless your
cooling is very good indeed, and this is nothing to worry about. AMD
specs the maximum die temperature (which is, however, always going to
be significantly higher than what you measure at or near the chip
surface) at 90 degrees. If an AMD chip is running at 55 degrees _when_
_idling_, you do not have enough cooling. Temperatures for Intel chips
should probably be 5 degrees or so lower.

>=20

Celsius is just another temperature scale. If you want to convert =
Fahrenheit to celsius, take you F temp, subtract 32=B0 from it, divide =
by 9, then multply by 5. Lloyd Labaw is also completely wrong about =
those max CPU temps also. A decent fan can run a high end processor with =
the 55=B0C range.

The microprocessors in auto engines are very complicated indeed - many being
the equivalent of modern computer processors. Ever hear of Windows Embedded.
Now, I am not saying that Windows runs your car .....

Bill, there's an easier way. For a rough guide 1°C rise = 2°F (it's actually
about 1.8°F). The formula given in my Collins Gem Ready Reference (a very
handy little book that I couldn't possibly be without) is (°F-32)/1.8 -
which just eliminates a step as 9/5 = 1.8. To go the opposite way (C > F)
simply reverse the symbols and figures ((°Cx1.8)+32).

[Jim Macklin]

It is hot for an Intel CPU and probably cool for an AMD. I
have an Intel Celeron and it runs about 37 C/ 100 F because
it is a different design from a P4. Each particular chip
has a design thermal rating.

The cooler the better, but each CPU has its own spec.
