@frostriz - Download ThrottleStop 9.3 or 9.3.1. It has some useful new features. A minor memory leak that was in TS 9.0 was fixed.
ThrottleStop is a small application designed to monitor for and correct the three main types of CPU throttling that are being used on many lapto

Your undervolt settings are OK. There is probably no way to improve upon these settings without your CPU becoming unstable. If you ever get a BSOD, add some voltage to the CPU cache. Most 9750H are only 100% stable with the cache at -125 mV. Some are stable at -130 mV. Very few are 100% stable with the cache at -138.7 mV. Do a few TS Bench 960M tests at 8 or 10 Threads. Make sure it does not report any errors. If you are stable, leave it as is.
That is a normal operating temperature for an Intel CPU. Any temperature under 100°C is OK. That is why Intel sets the default thermal throttling temperature to 100°C. Intel must have done lots of testing. They seem to be confident that their CPUs can run reliably at these high temperatures.
Lenovo ignored Intel's advice. They decided that 100°C is too high so they have lowered the thermal throttling temperature to a more conservative 94°C. Some engineer at Lenovo has made your CPU extra safe.
The new version of ThrottleStop has a feature in the Options window called PROCHOT Offset. If you do not see a lock icon near this setting, you can adjust the PROCHOT Offset value. This will change the thermal throttling temperature. Many laptops uses a PROCHOT Offset value of 3 so the CPU will start to thermal throttle at 97°C instead of the Intel recommended 100°C. Something new to play with. After you find a setting you like, you can use the Lock PROCHOT Offset option so this value does not change. Some Lenovo laptops are screwing around with this setting based on what power plan you are using. I frown on manufacturers doing stuff like this which is why I added the Lock option to ThrottleStop.
If some specific games are pushing your CPU up over 90°C and that does not make you feel comfortable, I would create a new TS profile and I would lower the turbo ratio limits. This will slow the CPU down so it puts out less heat. I prefer a hot and fast CPU but the slow down option is there if you need it.
