Hello all, System specs (Purchased Feb, 2017): BIOS: EVOC 1.06.09EVOC v2, 04/12/2017 CPU: 7700K RAM: Kingston 2400 MHz (2x8GB) GPU: 1070 MXM SSD: Samsung 850 EVO 1TB WiFi/BT: Intel 8265 Approximately 2 weeks ago, I received the Windows 10 Creators Update (10.0.15063 Build 15063) and attempted to use disk cleanup to delete the old Windows installation folders that were created after the fact because I felt comfortable with the stability. Upon deletion, I was noticing some random freezing/lagging, so I decided to load my BIOS defaults because I felt that maybe my down-clocked 7700K might have something to do with it. After resetting the BIOS, things still felt wonky, so I decided to wipe the machine and re-install Windows. After doing so, things smoothed out with all my applications re-installed, but I was still experiencing issues with games. Upon loading a game or OCCT GPU benchmark, the system will function normally until it reaches ~70ish°C. After that, it powers off, as if it were a thermal protection scenario. To take better precautions, I went ahead and re-pasted the GPU/CPU and replaced the thermal pads. Thermals were down from previous testing, but I'm still experiencing power downs after thermals reach ~70ish°C. CPU/RAM Benchmarks/stress tests can run without issue. I found this to be an odd aspect to the issue, and wanted to further inspect what might be causing the power-downs. I noticed in event viewer that the Intel 8265 was crashing repeatedly on boot after these power-downs, so I ordered a replacement to troubleshoot. After testing the system with all the different RAM configuration and WiFi card configurations, I found no correlation, and that the power-downs would still continue to happen regardless. On a side note, I couldn't complete the built-in Windows Memory Diagnostic, as it would power-down mid test regardless of percentage. I also noticed that when I run the GPU load tests, that if I limit the load, the test would run fine without issue. After updating drivers and further testing with HID Evolution technical support, we noticed the issue still existed, and will be picking back up on troubleshooting today. This morning, I downloaded HWInfo64 to further inspect temperatures and logging, and found an interesting issue. My PCH (Platform Controller Hub) temperatures at IDLE ARE +100°C..... During a stress test of the CPU, the temperatures reach somewhere near 110°C. I swear I read somewhere that the maximum thermal limit of the Z170 Clevo motherboards was 111°C. When I run the GPU load test, the PCH thermals go above 111°C and I experience a power-down. I have no idea which IC package mounted on the motherboard, but I REALLY want to mitigate this issue with a heat-sink/thermal pad. So, does anyone know of the position of the PCH? Thanks in advance!
