i7 12800HX Thermal Throttling immediatly

[AlejandroAguilar]

Hey there! So I have a Lenovo Legion 7 16IAX7 with BIOS version K1CN45WW.
This machine runs an i7-12800HX and was running perfectly until past July 30th.

Now the CPU temperature practically sticks to the thermal throttle temperature as soon as it heats up, even on idle, with only background apps running and task manager showing CPU usage values under 5%.

I have been thoroughly trying to fix this issue, seeing if there is update, reverting to old graphics drivers, reverting recent Windows Update with no success.
Package temperature is still sticking or staying too close to the Thermal Throttle configuration.

I have tried to undervolt it a bit on Intel XTU, lowered Turbo Boost Power Max and no success either.

One weird thing is that, with Intel's Driver and Support assistant scan, current CPU voltage is "1.8" which is shown nowhere in Intel XTU or HwINFO, CPU-Z or any other tool. Is that voltage reading to be believed?

I have reverted BIOS to default values to avoid any misconfigurations and the behavior is still the same.

You will see that it will thermal throttle at 85°C because that is the max temperature it is set to on Lenovo Legion Toolkit.
