You can check the temperature of the processor on the BIOS of the motherboard, that should be the most acurate temperature for the processor.
Sorry for not being clear in my initial question, BIOS shows exactly the same thing - CPU temp around 8.0C
Is this temperature always the same one? or does it changes depending on the processor load?
It changes - when I tested the cpu under 100% load it went up to 13,5 -14,0.
In this case I would recommend testing this processor on another motherboard to see if it has the same behavior, make sure that you are reading the CPU temperature not the cores temperature.
I wish I could... this is dual core Intel Atom D510 (Pineview) - it is soldered to the motherboard. Bios calls this reading "Processor Temp".
I have similar problem. Boot it up cold and the BIOS will show either (approx.) 30 Deg. C or 70 Deg. C. Reboot and the BIOS might show 30 Deg. C or it might show 70 Deg. C. Reboot and it algain and it's anyone's guess; pick one 30 or 70.
And the BIOS temps. do not correspond to readings taken by Core Temp or System Information for Windows (SIW), even taking into consideration the additional heat build up during 20 seconds of booting.
My other problem (possibly related) is the fan header. No matter whether the BIOS is set to control the fan automatically or set to a specified %age of maximum, when it resumes from sleep the fan goes into overdrive (faster than "normal 100%" which means it's probably getting too much voltage after resume) and stays there until a hard boot. Burned out one fan already. I'm running a fan mainly out of fear of overheating since nothing seems to report the correct temp. That's scary on a system designed to be fanless; not being able to even have a clue how hot it is. With no accurate way of telling the temps I felt it would be better safe than sorry so I use a fan. It's ironic that the fan control can't control the fan which I added because the BIOS temperature sensor can't sense the temperature.
Finally, after about 5 days of use, now the fan header is dead. Well not totally dead. Some boots it will turn the fan real slow (and report some crazy speed in the BIOS). So I RMA'd the board to Newegg. I'll have the new board in tomorrow so I'll report back if I learn anything.
The same problem with my board.. It looks like the temperature is half of the actual temperature...
I can't find any info from intel...
Today i did update the bios, this didn't solve the issue..
Well, I hope that this is a problem that can be solved by bios update. I hate to be forced to return the board...
I will try to do that, but who should I contact for my country: Poland? it is not listed on the page provided.
If your country is not listed there, then you need to call the closest one to your country.
I contacted Intel in the Netherlands, but was connected to the UK.
The "technical support" guy told me this whas NOT the CPU temperature. but he could not explain me what it was then....
I tried to explain him that the CPU temperature showed by the hardware monitor in the Bios normaly is the CPU temperature.....
It is stated in degree Celcius... what else can it be....
This guy really had no idea..
I still think my board is not ok since the cpu temperature reading is half of the actual value. Or do all D510MO have this issue? It even is far below room temperature when i start the pc.
I have checked my other computers and the CPU temperature reading in the bios is normaly quite accurate.
I worry most about the temperature shut down function on the atom board. If the temperature reading is incorrect, will the overtemperature shutdown work properly?
If somebody else can tell me where to get some real technical support. Please let me know.
What should i do?
I would recommend contacting the local support and let them know that since the processor is embedded on the motherboard, the motherboard needs to be repalced.
You can refer the local agent to this forum, so he/she can check the trad of this conversation.
