Okay ,
I was told this was the best place to ask for information regarding the
amd64 cpu average temperatures
I have the amd 64 3200+ 2.2Ghz newcastle
I was wondering what temp it should run at normal operation and under a load
???? please any information or direction  about this subject would be most
appreciated , I currently have asuse probe 2 and also speed fan and everest
ultimate and they all read about the same  average normal operation 30
degrees celcius and 36 degress celsius under extreme 4 hour gaming session

Temperature questions can get you a "frosty" answer :-)

We could try walking through an example here - page 30, rightmost column.

This is not your processor, but this will do as a worked example:

       ^   ^
       |   |
       |   +---identifies the revision of the core - I think Newcastle is
CG rev.
       +--- A = socket 754

Tcase_max    = 70C (temp as measured by a thermocouple "glued to the lid")
Tcontrol_max = 70C (temp as measured by the CPU diode - as seen in Windows)
Tambient     = 42C (the computer case air temperature assumed, and this would
                    be a reasonably poorly cooled case, or the room temp would
                    be something like 35C.)
Thermal_resistance (theta_R) = 0.31C/W (thermal resistance of the boxed
cooler ?)
Thermal_Design_Power (TDP) Max_Pstate = 89W
Thermal_Design_Power (TDP) Min_Pstate = 35W

To work out the temperature of the CPU (Tcase), it is ambient + theta_R * TDP

If you were running Prime95, in a fairly hot computer case,
Tcase = 42 + 0.31C/W * 89W ==> 70C
In other words, if you used the stock cooler, and the air inside the computer
case was 42C, the processor would hit 70C. That is the max allowed, and
is at 100% CPU load.

In an air conditioned room, the ambient in the computer case will be
closer to 32C, so the CPU will be 60C or so.

When the processor drops to Min_Pstate (like idle in Windows desktop),
the equation becomes 42 + 0.31C/W * 35W = 53C.

If the computer case air was a bit cooler, like 32C, then the processor
would be 43C.

Now, in your case, if you use an aftermarket cooler, the theta_R will definitely
be better than 0.31C/W. Your processor will likely be a bit better (consumes
less power than the spec says) so that will make the temperature drop a bit.

Summary: I haven't a clue :-)

Your temperature is so low, you have nothing to worry about. Human
body temp is 37C, so your processor is cooler than you are.

Alright not that i can make heads or tails out of half of what you said the
main thing is that my temperatures are fairly normal and safe , i sincerly
appreciate the input and data ( even tho its over my head ) but i appreciate
the summary comment thank you

As a first step you can always use AMD's processor comparison page
( /) to get the basics.  There are 5
939 3200+s but this one is the CG stepping so it should be the Newcastle

Max temp 70C.

It's not as comprehensive as Paul's answer but it gives you the single most
important figure, the upper temperature limit.  Your load reading of 36C is
so far below 70 that you probably needn't bother with the rest.

Once again i thank you for your input and help ,
i guess i am worried about nothing i read all this stuff and now i feel abit
silly worrring about about my cpu temp

Au contraire.  It's an important thing to know.  Your temps may be good now
but what about in a year or two when your fan becomes clogged with dust or
whatever and they start to rise?  It's important to know what your system
limits are and what constitutes normal behaviour, so if and when things
start to change you know what's going on and can do something about it
before something fries unnecessarily.
