Confusion regarding CPU temperature

Postby qrious786 » Mon Oct 06, 2008 1:10 pm

Hi Support,

I've been using another software (Lavalys Everest Ultimate Ed.) for temperature monitoring until recently but now I'm switching to Hmonitor due to its simple interface and convenience (it does exactly what I want and nothing more).

I have a confusion regarding CPU temperature being reported by Hmonitor software. The Hmonitor reports CPU1 temperature value as 54*C which is quite high (I have no issue of heat in my room etc.). The other software (Lavalys Everest) reports the CPU temperature comparable to Mainboard temperature i.e. 40*C. Could you please help me understand the ambiguity?

There is another temperature reading being shown as Temp3; what does this correspond to? Could it be the CPU temperature because this value is comparable to Mainboard temperature?

I've pasted the report below for your review. Thanks in advance for your kind help.

Actually, 54C degrees looks much more reliable for your CPU model (Intel(R) Pentium(R) D CPU 3.40GHz).
But If you prefer to see 40 degrees as CPU temperature, just change default caption ;-)

Also, you could perform stress test for the CPU:
1. Enable data log in Hmonitor with minimum period (2 sec);
2. Enable Plot for temperatures in Hmonitor;
2. Run some CPU-heavy application (ie Primes or Seti) for 5-10Min and watch the temperatures;
3. Stop it and wait another 5 mins;
The value that is most changeable is the CPU temp!

By the way, how about register your copy?

Thank you for your reply.

I've been monitoring the CPU temperature closely from last few days and noticed that CPU1 temperature raises very quickly when CPU is under stress (50% - 90% utilization) even briefly (10-20 seconds). The temperature raises to 66*C easily and this is bothering me since the maximum temperature listed for Pentium D 950 is 68.4*C at Intel's site. Could you please tell me if I'm missing something? Are these values of temperature (66*C - 68*C) normal?

I definitely would register it after checking my employer in couple of days.

Thank you.
