Hi guys, it seems that I have some really strange issue with my CPU temp. Long story in short: Mobo: Asus R6E, bios: 1002 CPU: 7900X - non delided - Water block (EK CPU+VRM combo unit) GPU: Strix 1080 TI - Water block (EK Block) Cooling loop: Full custom loop, 360PE(45mm) + 360SE(30mm) + EK 140 Res + D5 Pump combo (glass) + 6 EK Vadar fans 2200Rpm Case: Be Quiet! Darkbase Pro 900 My temps are all fine, except the CPU. But the CPU is horrible: Under load at Stock(!) the temp goes up to 70°C-75°C. If I overclock it a bit to 4.5 Ghz, at 1.15V (Stable, no issues and still under the recommended 1.2V) CPU package temp goes up to 100-102°C under Cinebench. Additional info: Room temp around 23°C, Water temp at idle 31°C - 38°C under heavy load, GPU at 32°C idle - 45°C in gaming, VRM at 36°C idle - 65°C under heavy load. Pump is always on 100%. Fan speeds are irrelevant since the water temp never exceeds 38°C. CPU 35-38°C idle - load temps...100°C or higher... I know that the Skylake-X CPUs are hot, but I have never seen temps like these for the CPU under this low voltage. I have tried the following things: Reseat the CPU block. Re-apply thermal paste. Do you have any suggestions what can cause these temps?
