Fatal1ty Z170 GamingITX/ac turns-off. PCH problem?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi again,
Recently I have noticed some automatic switch offs in my system. After monitoring everything I have found that PCH temp is not stable. It jumps more than 10ºC in just one second and also the min temp registered is too low (even lower than ambient temperature which is approximately 20ºC). I have not found very high temps, so I believe that a low temp could have cause the power off.

You can see in the following pictures what HWInfo monitors. 

My config:
- Fatal1ty Z170 Gaming-ITX/ac
- Fractal Design Node 304.
- i7 6700K (no overclock yet)
- Noctua NH12S
- 2x8GB Gskill F4-3000C15-8GVR (no overclock yet)
- 960 Pro NVMe SSD.
- WD HDD.
- Be Quiet Pure Power L8 500w.
- MSI geforce 970 gaming
- Windows 10 Pro.

I hope you can help me to fix this problem.

Cheers, 
Marcos

	There is no way those reported temps on the PCH are accurate. More than likely HWinfo is misreading them or, less likely, the sensor is not working properly. There is no possible way anything on the motherboard could be that far under room temp without external influence (chilled air, LN2 etc). Check your event logs for more info on unscheduled shutdowns, it should provide more information as to the cause.
