Motherboard pushing excessive voltage (ASUS MCE / Gigabyte Enhanced)
Default motherboard firmware disables Intel/AMD factory power limits, pumping upwards of 1.45V into the CPU and generating over 300W of heat.
Internal desktop parts run on harmless 12V DC voltage and cannot shock you. Simply unplug the wall power cable first, then touch the unpainted metal case frame to ground static electricity.
Common Symptoms & Tells
- CPU pulls 250W-320W in benchmarks and hits 100°C on a 360mm AIO cooler
- CPU Vcore voltages spike above 1.40V in HWiNFO
- System crashes in Cinebench or rendering after 30 seconds
Interactive Fix Checklist
0 of 5 steps completedSafety power-off and discharge
Shut down the PC, turn off the power supply rocker switch (O), and unplug the AC power cord from the wall outlet. Press the front power button once while unplugged to discharge residual capacitor energy before touching any internal components.
Disable ASUS MultiCore Enhancement / MSI Enhanced Turbo
In under Ai Tweaker / Overclocking, find 'ASUS MultiCore Enhancement' and change from 'Auto - Enforce All Limits' to 'Disabled - Enforce All Limits'.
Apply Intel Baseline / Default Power Profile
Update to the latest version containing the Intel Default Settings profile. CRITICAL SAFETY: Never turn off, reset, or unplug the PC while the update is flashing to avoid corrupting the motherboard EEPROM. Ensure PL1 (Long Duration) is set to 125W or 253W according to Intel specifications.
Apply negative voltage offset (Undervolt)
In , set CPU Core Voltage mode to 'Offset Mode', select '-', and enter a conservative offset of 0.050V (-50mV) to drop temperatures by 5-10°C with zero performance loss.
Configure AMD Precision Boost Overdrive Curve Optimizer
On Ryzen processors, enable PBO Curve Optimizer → All Cores → Negative → start with 15 or 20 for cooler operating temperatures.
