Bug Report: Abnormal CPU Power Behavior After Clean Install of Windows 11 on PHN (16-71)

⚠️ Bug Report: Abnormal CPU Power Behavior After Clean Install of Windows 11 on Acer Predator Helios Neo 16 (PHN16-72)

🔧 Issue Summary:

After performing a clean installation of Windows 11 (version 24H2) on the Acer Predator Helios Neo 16 (PHN16-72), the CPU (Intel Core i7-13700HX) begins drawing abnormally high wattage (~100W) consistently during gaming — even in titles that are not CPU intensive.

This causes excessive overheating (100°C) and potential thermal throttling. This behavior was not present on the factory-installed Windows 11 OS or when upgrading to Windows 11 through Windows 10.

💻 System Specs:

Model: Acer Predator Helios Neo 16 (PHN16-72)
CPU: Intel Core i7-13700HX
GPU: NVIDIA RTX 4060
BIOS Version: 1.18
Windows Version (Affected): Windows 11 24H2, Build 26100
Installation Method: Tried both Media Creation Tool and ISO (via Rufus)
Drivers: Installed automatically by Windows Update
Power Plan: High Performance (same as before — not the issue)
Monitoring Tool: MSI Afterburner

🎮 Affected Games & Behavior:

God of War (2018)
Need for Speed Unbound
Valorant
Resident evil 2 and 3 remakes
Forza Horizon 5

In these titles, the CPU ramps to 100W power draw even when unnecessary, giving higher FPS but causing dangerously high temps (~100°C). This happens consistently after clean installs, regardless of power plan settings.

✅ Workaround Discovered:

If the user first installs Windows 10 and then upgrades to Windows 11, this issue does not occur.

In this case, the CPU behaves correctly:

Draws power according to actual game load
Temperatures stay under control
No performance or thermal issues

🧪 Steps to Reproduce:

Perform a clean install of Windows 11 (24H2 build 26100) using the Media Creation Tool or ISO.
Allow Windows to auto-install all drivers.
Launch games like Valorant or God of War 2018 or any cpu intensive fps games.
Observe CPU power draw ramping to ~100W and temperatures hitting 100°C.
Reinstall Windows 10 → upgrade to Windows 11 → test the same games → issue is gone.

📣 Request:

Please investigate the cause of this power behavior discrepancy between:

Clean-installed Windows 11
Windows 11 upgraded from Windows 10
On this specific hardware model.

It appears that power management, firmware configs, or thermal limits are not being properly configured during a clean Win11 installation.

📝 Postscript (P.S.):

This is not a hardware issue. The CPU, thermal paste, and fans are all functioning correctly — this is purely a software or firmware-level power management problem. I'm reporting this because other users with the same laptop may unknowingly put their systems under unsafe thermal load after a clean install of Windows 11. I hope this helps surface the issue and lead to an official fix. I'm happy to provide logs, screenshots, or reproduce the issue again if necessary.
