I'm worried for the sensor results.
-----------------------------------------------------------
My system is:
Athlon xp 2000+ overclocked to 2600+ 2100 mhz
Kingston HiperX 512 3200 ddr
Asus A7N8X-X
Geforce 6600 AGP 128 MB
Windows XP SP2
-----------------------------------------------------------
Temperatures:
Motherboard 37 C
CPU 39 C
CPU Diode 72 C


Note: My pc works just fine but I don't want my CPU burn.

"CPU" temperature means the temperature measured around the CPU socket, whereas "CPU Diode" temperature means the temperature of the CPU core.

On Asus boards make sure to use Asus PC Probe to check if the measured "CPU Diode" temperature means anything. In the case that temperature is not displayed in Asus PC Probe, then you can simply ignore it and use "CPU" temperature only.

Thanks for the help. I'll download the asus probe and test it

I tried with motherboard monitor and the CPU diode temp is the same as the everest. Should I be worried?

Check Asus PC Probe.

Hmmm. I have the latest version of Everest Ultimate and an Intel Quad core QX6700. Everest is reporting 37C for the CPU, and 58, 51, 52, and 49 for the CPU cores. Asus PC Probe only reports the lower 37C. Are you saying I can ignore the four core temps?

Thanks,

you could. although it is good to monitor as it allows you knowledge of how well your heat sink is performing. if your pc is running 5-10C hotter idle than it normally does normally, and the temp of the air going into your pc isnt hotter than normal, it is a good sign that your heat sink and case fans, and your pc entirely for that matter, could use a cleaning with a can of air or two.

does the "cpu" not the cores, raise in temp during the system stability test?

No, both the CPU temp and the core temps go up.

In the case you have core temperature for all 4 cores, then they're the more important values, since they're read directly from the processor, using the built-in temperature diodes of each core.

rich. those temps are fine if they go higher than say 50c it wouls be worth checking the.you can install a better fan on cp and an case fan . dont forget to ''grease'' the cpu when u fit another fan.. luck

[RichardI]

Thanks roughrider and Fiery. I've been trying to find out what are acceptable temps for those cores with no luck. I have seen them as highas 70 deg. C. and that's with an aftermarket fan. Nothing is overclocked on my system. Is there a link somewhere that will show me what the acceptable ranges are?
Thanks

Core 2 Duo processors tend to have either 85 Celsius or 100 Celsius Tjmax (max. junction temperature) range. Hence anything under 85 Celsius is just fine.

Pentium 4 processors start to slow themselves down (a.k.a. throttling) to protect from overheating at around 80 Celsius. Hence CPU temperature should never exceed 80 Celsius, and actually under 70 Celsius it's normal.

CPU fans tend to spin between 800 RPM and 8000 RPM, so 2400 RPM is again normal.

athlon x2 4800

mb Asus m2a-vm

pc probe shows cpu temps between 37C-71C

everest UE 4 shows

core I till 37C

core II till 60C

core always 25-27C

AUX always in coincidence with asus Pc Probe 37C-71C

by the way - the system is always stabil (nothing's wrong)

shoud i worry about something?
thanks!

71 Celsius is a bit too high for CPU temperature. The rest should be fine.

Why the "CPU Diode" temperature is lower than "CPU" temperature?

"CPU" temperature is measured by the motherboard sensor chip, whereas "CPU Diode" is measured by the CPU itself. Such difference is absolutely normal.

Does it mean that CPU has instruction which returns the value of CPU Diode temperature
even if the motherboard has no sensor chip?

I have another computer with K6-2+ CPU which has CPU Diode
but the motherboard has no sensor chip and Everest didn't show
neither CPU or CPU Diode temperature.

(I was about to think that AMD Athlon 64 3500+ AM2 has Peltier inside
if the core "CPU Diode" temperature is lower than the outside "CPU" temperature! )

Yes, it works exactly like that.

I have another computer with K6-2+ CPU which has CPU Diode
but the motherboard has no sensor chip and Everest didn't show
neither CPU or CPU Diode temperature.

K5, K6 and K7-class processors do not have a built-in temperature diode.
