Biostar TA75A+ wrong temps

Recommended Posts

Hi.

 

So, as the title says, wrong temps. My BIOS reports the correct temps I think (37-40 celsius) but then, when I start AIDA in Windows, I see values like 11-25 celsius... I think that is not true since I am using air cooling..

 

As said, my motherboard is TA75A+. I saw there is another topic too with same problem. 

 

Also, there is one thing. When i run stability test, AIDA reports my CPU is 46-48 celsius while doing that. The thing is that, is this reliable value then when CPU is under load or should I try to reset my PC and go to BIOS fast and look the "right" temp?

 

CPU is AMD A8-3870K.

 

Here is temps before stability test.

And here is while stability test is running.

The question is that, are those values while CPU is under load any reliable or  are they wrong? While idle or normal using they are clearly wrong like you see in first picture. But under load temps, are they any correct?

 

What could this problem be?

 

It is not anything serious, since BIOS reads it correctly and controls the fan correct too. So nothing wrong in hardware, only something is wrong in software. BIOS knows the right temp, controls fan good so no overheating happening. (as you see the CPU fan raised from 800 to 1200rpm in pictures) Software just doesn't read temps correct.. 

If it does matter what cooler I use, my cooler is Thermalright True Spirit 120.

 

If more info needed, I will give them.

 

Edit:

I decided to do reset while running stability test and go to BIOS and BIOS showed CPU Temp as 45 celsius. I reseted my PC when CPU was at 48 celsius. Sure CPU cools few celsius' down while it's not on load while going to BIOS. So it looks like while CPU is on load, the temp is quite correct like it should in AIDA... But while in normal usage, it is wrong in AIDA. But BIOS knows always the right temp. When I start my computer when it has not been used, BIOS reports temps about 29-35 celsius usually when starting up (It's quite warm in my room) and I'm quite sure this is correct. But then AIDA reads temp wrong in normal use/idle. While CPU is on load it looks like AIDA reads temp quite correct.. What causes this?

 

And sorry for my bad english..

 

This story in short: BIOS reads correct temp always, AIDA doesn't. (Except when CPU is load maybe?)

Please right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> ISA Sensor Dump.  Copy-paste the full results into this topic.

 

Using that data we may be able to calibrate the AIDA64 sensor module to better support your motherboard.  But please note that the core temperatures are measured via the on-die temperature diode of your processor.  And most FM1, FM2 and AM3+ socket based AMD processors feature a hardware issue in their temperature diodes that yields to very low temperature readouts at idle -- usually way below ambient (room) temperature.  The measured core temperatures only make sense when the CPU is under load.

 


Thanks,

Fiery

There is ISA Sensor Dump. And yes, that what you said happens. Way below ambient room temp like you said and makes sense when under load.

Thank you for the feedback.  As I wrote above...

 

"But please note that the core temperatures are measured via the on-die temperature diode of your processor.  And most FM1, FM2 and AM3+ socket based AMD processors feature a hardware issue in their temperature diodes that yields to very low temperature readouts at idle -- usually way below ambient (room) temperature.  The measured core temperatures only make sense when the CPU is under load"

 

... core temperatures are independent from motherboard sensor calibration, and the issue you experience cannot be fixed from software, since it's a hardware issue.
