The processor is not made out of water so the boiling point of water doesn’t affect it

In fact you will get the best performance at 95C because to decrease it means to decrease the clocks

If you mean to get a better cooling solution that would be better, but then running it at 95C with that better cooling solution would be better again

Once you reach a cooling solution that can take it to the maximum clocks, then there will be no performance benefit between 70C and 95C at the same clocks and you can reduce the fan speed to hit the higher temperature at less noise
