Z77 PCH Diode shows 43 °C always!

Recommended Posts

(Asus Maximus V Gene) Z77 PCH Diode shows 43°C always... any process, any loading, any environment temp. - no change, 43°C ... I think, it`s impossible :)

 

(AIDA 2.85.2406, Win7-64 SP1)

I have an Asrock Z77 Extreme4 and my PCH Diode has never changed once from 43C. That doesn't seem correct. Not even one degree up or down.

Still same issue with Win 7 and Win 8

I always run the latest beta.

We found Intel 7 Series Chipset PCH Datasheet

The PCH incorporates one on-die Digital thermal sensor (DTS) for thermal
management. The thermal sensor can provide PCH temperature information to an EC
or SIO device that can be used to determine how to control the fans. The normal
readable temperature range of the PCH thermal sensor is from 53 °C to 134 °C. Some
parts can read down to 43 °C but this is part to part dependent.

Is it true?

It's not useless at all.  You just have to keep in mind that "43C" means "under 44C" ;)

      Hi again Fiery. Got this new Maximus XI Extreme Z390 . All sensor readings appear to be there  except for the vrm and pch sensor.  There is a sensor reading for the motherboard but the other two are missing. I have attached the isadump and ecdump files for you to work your magic. Thanks in advance for any help.
