Product: Spectre x360
Operating System: Microsoft Windows 10 (64-bit)

I received a replacement work laptop which is an HP Spectre x360 a few weeks ago. This morning the laptop is extreamely hot, I had noticed this a few times when the laptop was plugged in, but never to this extent. 

 

It appears to me that the reason behind this is that the CPU is contantly turbo booting to 3.8 GHz, obviously that is producing alot of heat. There is nothing running on the machine however which is causing this, the CPU is running at 8 - 10 % with web browsing yet it is running at a constent maximum overclock. Its doing this from startup, not just in Windows. I believe that even in a high performance mode the CPU should only clock up to the speed required, not constently sit at the highest clock speed. 

 

I've read some forums post about changing the power options to limit the clock speed, if the clock speed is supposed to be dynamic based on usage I don't see why I should need to. This may have always been occuring but I hadn't noticed as I usually run it on battery.

 

This is a fresh Windows professional build straight from the ISO. I have updated all drivers and bios. I have not applied any updates this week as of yet and all I have running right now is a browser and a couple of MS apps like Skype / Teams.  CPU is currently around 12 % and the CPU is at 3.8 GHz. 

 

Has anyone else experienced this issue?

Ok think I found the reason for the turbo boost being pegged to maximum, it seems to be the high performance plan which does it.

 

I turned it to high performance this morning after the heating issue began to see what difference it made.  Now I have turned it to balanced it no longer seems to be 100% turbo boost.

 

I had the heating issue this morning but seems fine now. One difference from this morning to now is that the battery is now 100%. Not sure if this could explain the additional heat being produced. 

 

I'll keep and eye and see how things progress.

I have the same issue as you.

 

I've been searching around why my notebook is very hot when charging and i found your post that helped me identify the problem.

 

It's the same as yours. When energy plan is at Better perfomance, CPU stays around 3 and 3.4ghz and CPU Temp goes to 70° C and even 80° C. When changing plan to Best Performance, CPU instantly slows to 1.6Ghz and temperature to 50° C.

 

Now I have to find why it heats like that and why cpu goes so high.
