Hi,
I have a AMD 2200+, the bios revision is 1010.
When i switch on my computer and go in the bios setup, the CPU temperature
shown is 75°C ... quite high ...
When i boot, the Asus Probe utility shown me a temperature of 45°C ... which
seems more acceptable ...
Can someone tell me temperature are shown ... i wonder wich one of the CPU
or my motherboard maybe be deficient ...
 
Asus probe takes the temperature on the socket. Obviously 8 to 10 °C below
the CPU die. This means that the CPU temp is around 83/85 °C too hot, place
a cup <joke> in the case, the CPU is gonna melt !!!!

Install Mother Board Monitor instead. It monitors the diode inside the CPU,
on the die. Pretty much accurate.
Provised as well fan and voltage monitoring, adjustable thresholds, mail
capabilities, ... and __audible__ alarms.

Keep the temp well below the ratings. If my memory doesn't deserves me, the
limit is 85 °C (Please verify on AMD site).
At 55 °C you should consider that it's the limit you stay below for
reliability reasons and CPU life span.
Also this will give provision in case of any unexpected event. Sometimes
when the computer freezes, it happens that the temp raises of more than 15
°C.

If you're not able to keep the temp around or below 50 °C (at 23°C room
temp), add a side fan in front of the chipset.
Dunno where it is on the X version but on the regular one it's located below
and close to the CPU, the influence is great.

A two-fan equipped PSU is also very useful. If not, add a fan on the rear to
extract the hot air sucked by the HSF.

I won 15 °C with the two fans. Worth to do it.

check if your fan is installed properly I got the same issue with this mobo

Are you certain the heatsink is installed properly ?
The heatsink can be rotated 180 degrees and installed.
When installed in one orientation, the contact area of
the heatsink lines up with the die - if you rotate the
heatsink, the heatsink is no longer lined up with the
die.

So, take the heatsink off, and verify the alignment.
Use a thin application of thermal compound on the die,
to fill the gap between the heatsink and the die. When
you reassemble the heatsink on the CPU, I think the
temperature will measure a lot lower.

Some of the A7N8X boards have a diode temperature sensor
chip. This chip amplifies and measures the small
voltage developed across the temp diode on the CPU die,
and will turn off the computer if the die temp reaches
around 85C or so. That is the circuit placed on the
board, to prevent the Athlon from burning up. If your
CPU was really that hot, it would probably crash.
