System Specs
Model: ASUS ROG Strix G17 (G713PI)
CPU: AMD Ryzen 9 7940HX (16 cores / 32 threads)
GPU: NVIDIA RTX 4070
RAM: 32 GB DDR5
SSD: 1 TB NVMe
BIOS Version: 336 (latest as of Nov 2025)
OS: Windows 10 Pro 64-bit
I bought my laptop in December 2024, and it ran perfectly fine until about a week ago — that’s when I started facing serious heating issues and random shutdowns.
I didn’t install or update anything major before it started happening (no BIOS update, no new drivers, nothing noticeable).
Suddenly, the laptop began shutting down randomly without warning.
After checking Event Viewer, all I found was the usual “Kernel-Power 41” message.
So I started digging deeper and noticed my CPU temperature was extremely high — sitting between 95–105°C, even while idling with only Brave and Discord open.
When I checked Task Manager, everything looked normal except for one thing:
to be honest, I don’t know the behavior of the CPU in its normal state, but I’m sure the speed wasn’t fine because it was stuck above 4.6 GHz at idle and there was no heavy load running.
What I Tried So Far
- Changed Windows Power Plan:
Set Maximum processor state = 99% → disables Turbo Boost. - Uninstalled Armoury Crate completely and deleted all ASUS background services.
- Installed G-Helper and created a custom fan curve (fans ramp up earlier).
- Undervolted the CPU by -15 mV in BIOS.
- Checked fans and cleaned dust from vents.
- Completely reinstalled Windows 10 (clean format).
Current Situation
I use 2 profiles in G-Helper:
1- Silent
In the Silent option, I disabled the Boost mode, and as a result, the CPU speed decreased down to around 2.35 GHz and didn’t go higher.
The temperature became much better than before (60–80°C), but I still faced one random shutdown during a heavy load in this mode.
2- Balanced
In the Balanced option, I enabled the Boost mode to Efficient Aggressive.
Here, the CPU speed fluctuates around 3.9–4.7 GHz, and the temperature in idle reaches up to 95°C.
What I’m Planning Next
I’m planning to replace the thermal paste (my laptop came with factory liquid metal) and use PTM7950 as my next step.
Any thoughts or better suggestions before I go ahead with repasting?
Could this still be a power delivery / EC issue, or does it sound like a clear thermal contact problem?
