Question When plugged in, cpu draws 11W and Laptop heats to 101C on idle

[MileFamilija]

Hello, recently when I plug in my laptop to charge CPU (Ryzen 5 3550H) starts drawing 11W, and heats to 98-101C on idle, on idle CPU draws 3-4W and heats to 40-50C. I have tried

• Changing the power plan
• Changing the default GPU (Nvidia control panel)
• Setting Maximize Battery instead of Maximize Peformacne

Any help?
Thanks.

Is it getting to 101 under load? or Idle? That CPU has a max operating temp of 105 degrees so if that is the temps under load that might be normal (for a laptop's cooling solution anyways). It's a relatively new CPU so the laptop that it was placed on should be at most 4 years old. You can try to clear some dust from the system to unclog airflow, that will surely help if it has never been cleaned. A repasting might also help if you feel qualified enough to do it, I know thermal pastes usually have a life span of 6-8 years but factory pastes are typically cheap junk compared to third party solutions like Arctic Silver 5.

You can also try undervolting your CPU, but be careful.

AMD CPUs report the hottest thing as the "CPU" temperature. It's probably a good 15C cooler than what's being reported.

You could try disabling turbo boost if you don't really need it, or change the behavior. See https://forums.tomshardware.com/threads/something-to-consider-for-laptops.3737865/

No under heavy load (example flight sim 2020) it stays in 90C sometimes it spikes to 101C

I don't have boost in advanced power settings

Someone may correct me if I am wrong but that seems normal. That is a hot CPU and consistent 90s with occasional 100 spikes sounds fine. Do you want to try to clean the dust from the system and attempt a repaste? That can help drop you a few degrees if your system is dirty. Undervolting the CPU will also definitely help lower temps. Do you have quiet fan profiles enabled? That typically sacrifices thermal performance for a quieter fan speed.

You have to modify the registry, the instructions are in the post.

Alternatively, open up PowerShell as an Administrator and input the following: powercfg -attributes sub_processor perfboostmode -attrib_hide

nope fans are at full speed all the time

its on aggressive (on battery & plugged in) on what should I put it?

Either Disabled to turn off turbo boost, or try one of the "Efficient" settings.

Personally I create a separate power plan to disable turbo boost if I'm not doing anything heavy like playing a game.

Tried everything and still nothing 95C on idle

Look at the temperature using HWiNFO. It's usually more reliable and provides more information

You are sending mixed messages, are you experiencing 95 degrees on idle or under load?

min. 95C, max. 102C
avg. 100C, Cpu drawing: 11W
on idle these are the temps while plugged in

sorry for late reply, everything is the same, it jumps to 101-102C, throttles and reduces the temp to 95C and going in a loop
to add on that cpu clock is constantly at boost clock (3GHz - 3.7GHz)
