A Maximum processor state setting of 99% will disable Intel Turbo Boost. This will leave a 9750H running at a maximum speed of 2.60 GHz. It is perfectly safe to run a CPU at far below its rated speed. Many games depend more on GPU speed and not so much on CPU speed. For those kind of games, you may not notice any significant loss ofperformance.

Temperatures of 75°C, 80°C, 90°C and even 95°C are all perfectly safe operating temperatures for an Intel Core i CPU. That is why Intel sets the thermal throttling temperature to 100°C. If any of these temperatures were not safe, Intel could easily lower the thermal throttling temperature.

Most laptop manufacturers are using a value called PROCHOT Offset. This will force the CPU to start thermal throttling before it reaches the Intel 100°C spec. No real need to do this but it does provide an additional safety margin.
