I'll be doing some testing and passing on the findings here as well as to PCS Support. Step 2 DID bring back Processor Power Management, so I should be able to drop down my maximum processor to 99% or even lower to 90% to see if that brings to temps down, doing some research online seems to point that turning this down 1%-10% makes huge differences supposedly on HP Omen laptops while still keeping the performance at the level one would expect, so hopefully works the same on the PCS Machines. Step 2 did, as well as PCS tech support enabling a few other things in the registry. Seems Windows/Microsoft DOES hide these options which isn't ideal for users like us who want to manage this ourselves.

I got a tech who investigated more as well as me doing my own investigation and we found this. You can then modify it in the Advanced Power Options as you see fit. You would have to modify the registry to enable it. The options are there in the registry but are not enabled for view.

I re-installed Windows 10 on SSD1 in my device to see if that automatically brought back in my missing options - it didn't. I had a few questions and I raised this with PCS. Although PCS say this is in operating temperature, I wasn't fully happy and I researched more about how to bring temps down. I played Cyberpunk 2077 the other day and while in a menu the CPU temps were at 95 degrees, even with a cooler, I know Cyberpunk isn't fully optimised and is a fairly intensive game.
