Acer NITRO 5 515-53 - CPU overheat when ON charge

Hello to the community,

I have CPU heating issues with my brand new NITRO 5 515-53 (specs below) when I put it ON charge. as you can see in below screenshot (using NITROSENS), I'm getting instant increase in CPU temperature (with erratic peaks) the second I plug the laptop to its ACER original charger (without using any adapter in socket...). CPU temperature return to normal immediately after unplugging the charger.

Plugged (even battery 100% charged): I'm having peaks at 63C-78C with no/little activity and 87C-98C when under load (gaming).
Unplugged: I'm having steady 39C-42C with no/little activity and 45C-50C when under load (gaming).

has anyone experienced such a problem before ??

Thanks

Notice:
- Since I suspected charger malfunction, I tried to change the charger cord (from socket to charger) but saw no difference
- Specs: i7 8750H, 16Go RAM, GTX1050Ti, 256SSD + 1To HDD. I have heard that the i7 8750H suffers from overheat issues but for me seems to happen only when ON charge.

When on AC power your laptop allows the CPU to run at it's maximum TDP level and maximum turbo boost. When you unplug and use the battery, your laptop limits its TDP and turbo boost limit. In essence, your laptop is acting exactly as it should in terms of performance both on and off AC power. This isn't a faulty power brick/adapter.

You can decrease the temperatures when plugged in by undervolting the CPU with software, manually re-pasting the CPU die with better thermal paste, and/or increasing the fan RPM. This is all documented here on the forums and on YouTube for the Nitro 5.

Thank you tobimaru for your answer.

You were right, all I had to do to solve the problem was to limit the CPU "output" in power management settings and now I'm getting a happy 60C even under relatively heavy load.

How did you manage to solve? Could you share? I'm having the same problem with my Nitro 5

I have the same problem today, the notebook worked perfectly before I changed the thermal paste for a better one and then formatted it. Now I have reinstalled two operating systems but I keep the problem of "CPU overheat when ON charge"

sorry for my English

@velocito @abakarov @mvmmarcus hi , I just had the same issue today and this is how i resolved it , go to power plan settings go to power processor management , maximum processor state and the "Plugged in option" i turned it down to 50 and now its perfectly fine , however i think you could adjust this to ur likings enough so it dosent go to a dangerous temprature , my laptop is Acer nitro 5 / "AN515-57"

Hi!

I was having the same issue when my laptop was plugged in, the idle cpu temp was 82-89°C, I was looking at the power plan, and noticed that my "minimum processor state" (Its not english for me sorry, something like that), was set to 100% while charging, and 5% while functioning on battery. I turned it to 5%also and now my idle is 49°c, which is still a bit much, should I do something about it or is it okay?
