Question How to properly limit cpu usage in power options ?

[PeyoteFTW]

My laptop use ryzen 5 3500h cpu, and i want to limit the cpu to reduce temp because its reach 80-88c and sometimes 90c when gaming.
I look at the power options you able to limit the cpu state maximum and minimum.
Let's say i want to limit my cpu usage to 80% only. What percentage should i put in maximum and minimum state ?

Keep minimum to those 5% and set maximum to whatever gives you satisfactory performance without heating too much.
Do you know you can have multiple Power saving plans and you can instantly switch to any of them ?

Hey Mike, So i have to change plugged in from 100% to 5% in minimum state and change maximum state to whatever i want, correct ?

yes i do know how to make another power plan.

Correct, you can do it for battery operation too because it's not going to heat up any less.

 

[Does it work]

Cpu is safe upto 105, you could also potentially just undervolt/underclock the cpu in bios and work it that way

Is this right setting ?

Yes, that should work, just check if performance and temperatures are satisfactory. If youhave to change something, change only maximums.

I doubt that this will change the temps since everything auto adjusts nowadays,the laptop will take the lower CPU power to reduce the coolers RPM to make it quieter so it will still hit the same temps.

just closely monitor what service is using how much of your computer's resources and then take actions, manage that. Task manager is your friend, my mate

Cooler speed is adjusted by temperature, not load or CPU frequency.

Cooler speed is adjusted by temperature, not load or CPU frequency.

Then it will stay quieter for a little bit longer until it will hit the same temps and be the same amount of loud,same thing.

This whole exercise was to lower temperatures, so if it temps stay low so will cooler's RPM and sound with it.

The temperature lower drastically from 80c to 60c after i set to 80% because its only use 1,7ghz and also games run little bit stutter.
Is there a way to limit the ghz instead the cpu state, so i can limit it to 3ghz only because in full load my cpu reach 3,7ghz ?

Might be able to do it in BIOS if it supports the feature but CPU state also limits the frequency

Yeah but cpu state can't set exact number. i change it to 99% but it limit to 1,7ghz only.

I will check in bios later.

Has anything worked for you yet?
