CPU & Motherboard temperatures are the same (Asus P7P55D-E LX)

I have Intel QuadCore i5-760 @2.80GHz CPU on a ASUS P7P55D E-LX motherboard and I was wondering why are the temperatures of the board & CPU the same. I went to my BIOS to confirm the readings & the motherboard readings from the Bios & AIDA64 are the same except for the CPU which is off by 9 degrees celsius (AIDA64-=35 ; BIOS=44.5) Why is that? Which of the two readings do you suppose is accurate? I wouldn't want to go to my BIOS everytime just to monitor my CPU temperature, how do I make this right? Thank you for your time. Any help is greatly appreciated. Attached a screenshot of current readings.

Hello,

There is no error in these readings as far as I can see.

During the system startup and when you are in BIOS, the computer always check every components to ensure that it works, thus applying load to the CPU, hence 44.5 degrees. When the Core i5 isn't being utilized, then the temperature would be 35 degrees. Go to the System Stability Test within AIDA64 > Tools and stress the CPU and FPU. Shortly, you will notice that your CPU temperature is close to 44.5 degree or is at 44.5 degrees.

Hopefully this helps!

Hi,

This seems odd. Your motherboard temperature should not adhere to your processor temperature. Please give Core Temp and HWiNFO32 a try (also RealTemp, too!). If all three software, including AIDA64, reports motherboard and CPU temperature are the same, then there might be some motherboard sensor or DMI table error. If it is only AIDA64 that is giving this strange reading, please debug the sensor by right clicking on the status bar and select Debug Sensor [Console] or something like that. Either reply to this thread with the result (copy and paste) or take screenshot of the window (copy and paste is better). Fiery might be able to help you with the next beta release of AIDA64.

Hopefully this clears some things up! I wish I could be more of help to you.

Take care!

Upgraded to latest beta version 1734 and I can see that my motherboard's temp reading's normal. I think this version has fixed it. Thank you for being patient with me along with the fix. Appreciate it. If possible, given the time, could you please in plain simple English post a very simple summary of what caused the misinterpretation of the Mboard reading? Thank you again for the help.

On most motherboards (including most Asus boards) the motherboard temperature equals to the internal temperature reading of the sensor chip that is integrated on the motherboard PCB. On your motherboard however the sensor chip reads the motherboard temperature from a special register that is only used on a handful of Asus motherboards to measure temperature. So we simply had to modify the motherboard-specific sensor code for your motherboard to switch from the usual register to the special register :)
