My acer nitro AN515-57 have overheating and thermal throttling to 300HZ

Lemespnbio · November 22

The GPU is hitting 80 degrees and throttling power/clock down to 300. I checked via MSI Afterburner, and that’s all I can find. I can’t undervolt because this model is locked for such adjustments.

Things I’ve tried:

Changing power plans
Adjusting power management in NVIDIA settings
Tweaking the NVIDIA control panel configurations
Cleaning (the last cleaning was in March at a top-notch, authorized service center in my city)
Reinstalling Windows
Enabling and disabling virtualization
Other tweaks I can’t remember (and yes, MSI shows the thermal limit).

What should I do? I’m thinking of cleaning it again, replacing the thermal pads, and applying the best thermal paste available on the market.

My PC can’t even run Minecraft with satisfactory performance without stuttering every three seconds, whereas it used to run everything—even Red Dead Redemption 2—with excellent performance on high settings.

My pc hardware:

AN515-57

Intel i5 11400H

GTX 1650 4 gb

16gb de ram

SSD 1 tb NVME

Windows 11

Overheating can be caused by poor ventilation, dust buildup, or failing cooling fans. Prevention: Ensure that your computer is well-ventilated, regularly clean the dust from your components, and check that all cooling fans are functioning correctly.

To help reduce the temperature, you can place the Laptop on a hard, flat surface, clean the air vents and fans, adjust power settings, use a cooling pad, or turn off the Laptop when not in use. If necessary, monitoring the temperature and consulting a professional is also recommended.

Get a powerful 5-fan cooling pad the size of your laptop and reduce the Max. Processor Power state to 95% when on power. Also use Balanced Power Plan instead of Maximum Performance Power Plan. Up to 95°C. under heavy load no issues, the CPU can sustain 100°C.Disable NVIDIA/AMD Dedicated graphics card for a while and test your temps.

Also boot in safe mode and open task manager with GPU ENABLED and see if you can check the temperature. If its hot, then graphics is the issue. Undervolting means to decrease power draw for better cooling and higher clocks of the cpu and can be done using Throttle stop.

My problem is the GPU and not CPU…

Why should I disable exactly what I want to work as it should? If I use the balanced power plan, it only increases the interval between the micro stutters shown in the screenshots. Yes, I already use my PC on a cooling pad, and as I mentioned, it was cleaned in March and the thermal paste was replaced, so it's clean.

My model doesn't allow undervolting without a BIOS mod; it's blocked even in ThrottleStop. I wanted to undervolt the GPU, but Acer didn’t allow it due to this horrible factory lock that even prevents unlocking the undervolt.
