========================
Detailed description:
Hi, a couple of days ago I performed a clean installation of Windows 10 from an USB, an operation that I do about every 6 months to keep the OS running at maximum.

Unfortunately since the computer has restarted I have noticed a noticeable decrease in CPU performance.
In fact, the temperature monitoring software shows that the CPU never rises above 70 degrees, while before, at full load, it reached without problems more than 90 degrees. In addition, the fans run at a much lower rotation speed than they did before (and I believe that the rotation speed depends on the number of WATT absorbed by the CPU at a given moment as well as on the temperature).

These two elements may not be a problem in themselves, but this obviously translates into a significant drop in performance. To be clear, the CPU-z benchmark gives me a value of about 1000 points while before I got more or less 2000. In addition, the greater slowness is perceptible in all operations that require a considerable CPU load.

I therefore lost several hours trying to uninstall the CPU drivers, change the settings in the energy managment and set different values ​​in the system registry, asking the CPU to always go to the maximum but I have not reached the goal and the result has not changed.

I have the impression that after the reset, the CPU TDP has dropped to 15W, while from what I know on this laptop it is set to 25W by the manufacturer (and this would also explain the production of less heat and less use of the fans).

I therefore ask to be helped to find a solution since I often use the PC at full load and having half the power is a considerable inconvenience.

Thank you, have a nice day

Conform the tdp power in cpu z

Okay, thanks, but how can Ichange the TDP with CPU-z?

You cant change TDP power. Because asus has not modified the TDP in processor .
So no use. There are the softwares claiming it changes TDP , but in general it's not possible.

Moreover is seen almost users wants to their processor should uses Less temperature. But only you wants to more temperature.

Thank you for the time and responses.

So do you think there is nothing I can do to get the processor back as fast as before?
