Overheating of ACER PREDATOR HELIOS NEO 16S AI notebooks (HOW I SOLVED IT, FOR NOW)
I bought the aforementioned laptop about 7 months ago, and from the beginning, I noticed overheating problems. The temperatures fluctuated between 90-100 degrees Celsius. This caused black or blue screens on my machine. As you know, many of the CPU settings on this version of laptops are locked. Below, I'll explain how I solved it, so to speak. Now, my machine runs at a stable 50-60 degrees Celsius, without a cooling pad.
SOLUTION
I recently bought the same laptop and was looking for a solution to lower the temperature without undervolting my processor, since it's crazy to have the CPU reaching 75°C just watching a YouTube video on an external monitor. Luckily, I found a solution that's practically a hidden option in the power plan editor, which I'm going to share. I think it might work for any laptop, and I'm leaving it here for anyone who needs it:
Steps: Go to the Registry Editor and run it as administrator. Paste this: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7 Then go to Attributes, change the value from "1" to "2", and save.
Now, in the power plan editor, specifically in the advanced options, under "Processor Power Management," you'll find a hidden option called "Processor Performance Boost Mode." This mode forces the processor to exceed its maximum frequency as soon as possible, which is what causes overheating. If you're using an Intel processor, this option is usually set to "Aggressive," causing the processor to constantly exceed its maximum frequency. Simply disable it or switch it to "Enabled," as it instantly lowers the temperature (I disabled it).
My laptop was at 74°C at that moment, and after disabling it, it instantly dropped to a stable 50°C. Keep in mind that I don't have a cooling pad, and I have the maximum processor usage set to 99% in both cases, and the minimum processor usage set to 0% in both cases, as these were tricks I already knew and had modified before due to the same temperature problem.
It's also important to mention that, in my case, I had already performed several additional system optimizations and Windows configurations to improve performance and reduce CPU and GPU load, so I can't guarantee that it will work exactly the same for everyone or that they'll achieve the same temperature reduction.
Now, I'll have a laptop for many more years without any problems.
