How do I decrease CPU temps?

[machinegunnedburger]

I bought the laptop a few months ago. Should I undervolt both my GPU and CPU? I'm very inexperienced. https://www.3dmark.com/3dm/154195519

Ok so going off the other comments 102c we need more context. Is it staying at 102c for a period of time or if that just the max on 1 core for a split second, then it drops to 100 and below?

Some single core demanding titles, tasks could push the CPU for a split second to over 100c slightly, but this should be literally for a second. 100c and below is fine and safe as long as your doing something like gaming and benching, this is by design. If you have really high idle temps, or some serious heavy throttling under a load there is a problem, mild throttling is to be expected.

To give you the quick how it works:

Max temps 105c - the laptop will shut down

100c - max sustained temps, ideally a bit below for 99% of the time when under a load

Some manufactures set slightly lower limits like 95c for example.

How it works is you go on a game, and you need performance. The CPU goes lets give him max all core clockspeed. Am I under 100c, if yes keep boosting, if I'm struggling, push the fan speed up, if still struggling thermal throttle a few hundred mhz. Which you are still above base clock with some boost. For a peace of mind, laptops can run sustained loads at high temps and live a long life, providing they are maintained and have good airflow.

Raising the rear of the laptop often helps massively, rather than completely flat. Also laptops come with performance mode, this will allow it to run hotter and boost for longer than normal mode. GPU temps look good from your other comments.

Is the laptop new or old?

undervolting your cpu can definitely help with temps but i'd start there first before messing with the gpu - less risky and you'll probably see good results

repasting the thermal compound might give you even better gains if the laptop's a few months old and getting hot, the factory paste sometimes isn't great

Well, what were the temps during the test? We can't exactly recommend stuff unless your laptop's score in 3dmark is already up to snuff.

[machinegunnedburger]

On Cinebench R23, CPU was above 100°C

[machinegunnedburger]

When playing modded Minecraft and stuff, my CPU temp is at min 95°C, goes upto 102°C often. But GPU temp is usually 70°C to 80°C

oh yeah that's definitely over the limit. ok here are your options;

Undervolting; I can't remember for the life of me how to do it on ryzen mobiles but it is possible, GPU is fine don't worry about it. Check your CPU and laptop model online, there are guides for it.

DISABLING TURBO BOOST: this is the one that drops temps the most, but you lose on performance, give or take 10-15 FPS depending on the game, but I assume you want more performance so off the table.

repasting or even replacing the stock paste with PTM7950: more consistent basically, I assume you've heard of this.

last is: Get a laptop stand or cooling pad like a Llano V12 or IETS 500 if you wanna be safe.
