CPU fried? Excessive High Core Voltage

Hi everyone. I am using Q6600 for several years. Two days ago, I disassembled the whole system and did a cleaning, took out the CPU from the socket for inspection, re-apply thermal paste.

After assembled the system back, it didn't turn on. At last, I figured out one of the socket PIN was bent and touched another PIN.

I managed to repair the PIN. Then the system booted and worked fine, without any hang up or random re-boot during my two-day use.

However, I notice some strange readings of the system. The Core Voltage is 1.98 V, which according to Intel, is way above the 1.5 V limit.

The 5 V, 12 V are also more than 5% more than the rated voltage. I remember before the cleaning, it is about 1-2% variation.

In addition, the temperature of CPU at idle and full load is 10 deg Celsius higher than before.

I am curious whether the CPU or Motherboard or PSU is broken?

I have anther PSU at home, can be used for troubleshooting. But I am afraid of collateral damage, will the PSU be affected and go broken if the motherboard / CPU was already fried ?

What are the full load temperatures? Your temperatures are slightly lower than they are with mine at 23°C ambient. If you CPU VCORE was that high, it would burst in flames before you could load the OS.

HWMonitor obviously has difficulties reading values on your system. Check the PSU voltages in the BIOS or with a DVM.

Thx for the reply! You are right HWMonitor is not reading right. The readings in BIOS look much "normal".

When the ambient is 30'c, the full load temperatures when running Prime95 for 5 mins is about 90'c. Is this normal? thanks!
