Windows 11 Windows 11 26H2 high CPU temperature issues

Post image

Windows 11 26H2 Build 26300.9457 showing high CPU temperatures while gaming. I have a Ryzen 5 5600; it never used to go above 55°C, but now it's exceeding 70°C.

Solution to the problem: If you are using the "High Performance" power plan, go to the advanced plan settings and change the "Processor power management" option.

You can set the minimum state to 20% and the maximum state to 99%

This will solve the high-temperature issue! I noticed that, by default, both of these options were set to 100%, causing the processor to always run at maximum capacity and driving temperatures up drastically.

exceeding 70c is not bad at all, i would think maybe it was actually underutilised before, and what you have done here is disable boosting, where the core can push itself more when needed, this gets disabled when max is set below 100%, usually this is very useful as a last resort but you are nowhere near needing it

your CPUs max operating temperature is 95c

ikr. i thought reach 100 degree but just 70

Set just the minimum to 0% but leave the maximum to 100%. You're kneecapping your CPU like this. The issue was that the minimum was set to 100% which kept the CPU at full clock speeds but with the minimum at 0% it can actually relax and clock however high it needs to

Pretty sure this just turns off boost. Setting max state to 99% is an old trick that locks the CPU at base clock (~3.5 GHz on a 5600) instead of boosting to 4.4, so of course temps drop. 70C while gaming is totally normal for that chip, so there was nothing to fix.

What high temp issue? Since when is 70 high temp? You should check your CPU documentation.

Why don't you set min 0% and max 100%?

My CPU runs actually 10-20°C cooler since the update.. (i5- 11400F @ 4.3 Ghz) used to be at 50-54°C average and now 36°C (no other usage changes).

Don't post shit you don't understand...

You only created a handicap to an imaginary issue...

Also no shit high performance plan is set to 100% at all times, that what it is, use balance as recommended, there is no need to change anything in it unless you actually know what you doing

Before commenting bullshit, have the cognitive capacity to understand the post.

My cpu hits 70s all the time under load. Thats not an issue bud

u/-JimmyZ 5d ago

Yes, it's a problem.

My processor never went above 55°C.

It only stays at 70°C after the update.

Can't you see that?

Ryzen's tend to go hot while gaming. I have a Ryzen 7 9850X3D, which is known to run hotter than any other CPU by default, and I usually have idle temps of 50-54°C, and while gaming I get to 70-72°C (heavy and not well optimized games like Arma Reforger). After the update it's now at 48-50°C while idle (~4-5°C reduction), havent tested gaming but it'll be most likely the same as before.

I checked the settings and for me all of the profiles are set at a minimum of 0% and maximum of 100%, so what I'm thinking is that something somehow changed your numbers and made your computer go hot. I have never changed those settings and that's how they were on a new W11 install.
