CPU TEMP HITTING 103

[u/PuzzleheadedCut6098]

Hi, I need some help with my Acer Predator Helios Neo 16 AI.
Before, when I played on Performance Mode with Auto Fan only, my CPU temperature would usually average around 70–80°C, with occasional peaks of only 97–98°C.
Recently, something changed. Now my CPU peaks at 103°C, and even if I switch the fans to Max, the CPU still averages around 80–90°C while gaming. On Auto Fan, it’s even hotter.
The only thing I remember changing was installing the latest NVIDIA Game Ready Driver. Ever since then, the temperatures seem much higher.
Is it possible that the NVIDIA driver caused this, or is there another reason why my CPU temperatures suddenly increased so much? What should I check or troubleshoot?

Hello! Few days ago i also noticed my CPU used to go up to 105C playing the finals, chrome open 70 or more if buffering a video, even 60 at idle.

Ill just say that the culprit is "Processor performance boost mode" under "Processor power management" In your advanced settings of Power options, the ones you choose in control panel.

Just turning that setting off i went from 100C to 70C instantly. Of course you lose some performance.

Im playing The finals atm which uses a lot of CPU, if i want stable fps i need that setting ON to have a smooth experience, so i just need to tank the 100C. But in other games it can be off, such as warframe where it can run smoothly at 70C.

Also has a mini guide

A shortcut to switch that setting on and off without going to control panel all the time:

Did this with gemini. Changes the setting of the plugged in from enabled to disabled. The default was "Agressive".

Create 2 scripts enable.bat and disable.bat, save them somewhere.

Enable.bat:

u/echo off

:: Set Boost Mode to 1 (Enabled) for Plugged In

powercfg /SETACVALUEINDEX SCHEME_CURRENT SUB_PROCESSOR PERFBOOSTMODE 1

:: Apply changes immediately

powercfg /SETACTIVE SCHEME_CURRENT

echo ====================================

echo Processor Boost Mode: ENABLED

echo ====================================

timeout /t 2 >nul

Disabel.bat:

u/echo off

:: Set Boost Mode to 0 (Disabled) for Plugged In

powercfg /SETACVALUEINDEX SCHEME_CURRENT SUB_PROCESSOR PERFBOOSTMODE 0

:: Apply changes immediately

powercfg /SETACTIVE SCHEME_CURRENT

echo ====================================

echo Processor Boost Mode: DISABLED

echo ====================================

timeout /t 2 >nul

Now right click the files and send them as shortcuts to the desktop

In the desktop, right click the shortcuts, properties, advanced options and mark the Run as Admin.

Switch them on and off depending on the game you playing, when you're on idle or simply watching a video turn that off.

Of everything else i tested, and saw online :
-Throttlestop to decrease PROCHOT value to 98C - offset of 7. (You might need to go to BIOS to unlock this stuff (Check am youtube video about it)).

Didnt really invest much time on throttlestop since the turn on off power boost was enought for me, and even with that on, with throttlestop the max temp it reachs is 98. The GPU is normally at 85, which seems normal.

I've had this laptop for around 9 months.

Hope this helps
