Im running 2 AMD Opteron 244's on the MSI K8D Master FT motherboard.

Chip #1 65C
Chip #2 66C
Fan #1 3553
Fan #2 3750

Everything else in Speedfan is varies from the temp being low or right on.

Notice Fan #1 Running Slower yet Chip #1 is cooler then Chip #2.

These chip Temps are the equivelant of 149F and 150F. Now its said that if you touch the side of the FAN and it doesnt burn your finger that your chips are fine. Well i touch the side and it feels warm at most, the only thing is I have had some system stability problems. Once in awhile the system will just reboot, its odd because it will run fine for hours. I shut it down manually and start it up and sometimes 5min into a free reboot it will restart on me.

I have not overclocked my Server or atleast no intentionally. I've read somewhere about a sensor possible being screwed up and giving me the wrong Temp Readings, is there anyway to replace or repair this sensor? The BIOS gives me the same readings pretty much as speedfan.

Here are my Voltage readings, looks fine to me but im not an expert

VCOREA: 1.49V
VCOREB: 1.55V
+3.3V: 3.26V
+5V: 5.00V
+12V: 11.73V
-12V: -11.54V
-5V: -5.20V
+5VSB: 5.48V
VBAT: 0.38V
VCOREA: 1.52V
VINR0: 1.78V
+3.3V: 1.18V
+5V: 5.11V
+12V: 9.61V
-12V: 2.20V

I do unstand that the V's are related to the power supply, just seeing if you guys have any input on this either. Im using a JGE 465W PWS.

VBAT: 0.38V ???? That's too low. It should be something like 3V or 3.3V

Well, everything below VBAT seems to be strange. +12V at 9.61V? .... +3.3V at 1.18V?

The CPU temperature difference is also explained by your voltages: The first CPU is powered by just 1,5V while the second gets 1.55V. Higher voltages = higher temperatures. But that small difference of 0.05V is nothing critical. Don't worry about that.
BUT: 65 and 66°C is already pretty warm for the CPUs. Are these the temperatures at full load or idle? What is your systems temperature? Maybe you should improve the airflow in your case and/or add an exhaust fan at the back of your case.
Sometimes there are bugs in early BIOS revisions that read out too high temperatures. Do you have an actual BIOS revision or still the initial that was shipped with the board?

No, you can't fix the temp-sensors if they are damaged. The CPU-temperature should be detected by a sensor INSIDE the CPU. It's just important how the mainboards reads out the signals and translates them into the temperature. If one of these sensors fails it will be unrecoverable.
But with readings of 65° and 66°C it does not seem to be damaged.


Back to the Voltage-readouts:
From the top of your list down to +5VSB everything seems to be OK. Some values may be a little bit low (3.3V and 12V), but still OK. At least IF they are constant even under high system loads!
But the remaining values are weired. It does not make sense to read out 3.3V and 5V again. There are no split planes for these rails! There are PSUs available that have up to four independend 12V rails but none has split 3.3 or 5V rails. So a doubled read out does not make any sense AND even if it is read out twice the values should be identical.

I hope that the values at the end of the list are just nonsense and do NOT represent the real values of your system. If they are real they give you the reason for the reboots and stability problems.
