So I figured out a big part of my problem. You were on the right path with battery management. I was on max performance. So I dropped it to better performance and saw a 18c drop. So now I'm at 80-82c during a 10 minute stress test in xtu. This is with -0.150v core offset. Its the same at -0.130v. However, I still get thermal throttling from the cpu. Ran a GPU stress test with no issues and that runs nice and cool of 70c.
Any recommendations on stopping the throttling on the cpu, or at least reducing the frequency?

So o did a 4 hour stress test through XTU and through Prime95. Both passed. I dont know how to read Prime95 numbers. See the figures on XTU. Only issue is the CPU still throttles. Temperatures stay at about 80-82c. I will remove the graphite pads and use MX-4 and retest.
What else can I do to reduce CPU throttling, if I can at all.

I gave that a go and I'm in the same boat. I've set everything back to factory settings and re-ran the xtu test. Temperatures hover in the low 80's, still throttling.
I ran Cinebench benchmark and my scores are very low in comparison to when I first ran it when I got the laptop. Otherwise the system runs great.
I dont know if I'm overthinking this. I'm going to repaste it today and re-check it. If all else fails, I'll get a hold of Lenovo support and see what they say.

Great news! After removing the graphite pads and applying the MX-4 thermal compound, the X1 is running cooler than a cucumber. This is with -0.125v. While stress testing, the laptop would hover around 65-70c at 99-100% CPU utilization. So I'm really happy with the results. My benchmarks also sky rocketed too!
On the flip side, I am getting Power Limit Throttling. Even with this happening, my clocks are running at 3200-3800mhz while under stress. Any thoughts on stopping the PLT?
Thanks for all you help and input!

The X1 is not designed to be pushed hard like a desktop. The CPU power limit is there for a reason.
If you need a perforamnce machine, go build a desktop and get an i7-9900 CPU etc
