Z97 Gaming 7 Not Reading CPU Temps

[iveben.kruzen]

I have had the Z97 Gaming 7 installed since July/2014 and had no issues. Today when I booted up I noticed that the debug LED was not displaying the CPU temp just "00". In the bios it also does not display the CPU temp but the system temp is displayed. In AIDA64 the CPU temp is stuck at 40c but it shows all the single core temps correctly.

I have removed the boards battery, cleared the CMOS and updated the BIOS to 1.80. Still showing "00" when booted up and no CPU temps in the BIOS. Can't understand whats going on here, could it be a dead sensor on the board? Some help would be appreciated.

System Specs:

Windows 8.1 64
Samsung 840 Evo 1TB
i7 4790K
MSI Z97 Gaming 7
Corsair Vengeance 1866 16MB
PowerColor PCS+ R9 290
Creative SB X-Fi Titanium HD
NZXT Kraken X61

Running all current drivers

Hi,

It might be either motherboard or CPU.
I suggest that you speak to a friend (if they have Haswell chipset) or to local IT services/shop and ask for testing each out.

Thanks Nichrome. Unfortunately here where I live, that is not an easy thing to do as there are not to many IT places i would trust to have this done. I guess I'll have to look around to see if I can borrow a Z97 board or a Haswell Processor to rule out with component needs to be RMA'd.

If any one else can add any more insight I would be grateful.

i saw the same such case recently, after has been tested everything it turn out it was the mainboard
RMA and replaced the board and all worked fine again

Was talking to MSI tech and they said to RMA it, so off she goes. Back to the HTPC as the primary
