Predator Helios Neo 16 i9-14900HX-after update to Win11 24H2-CPU-boiling abnormally hot while idle.

Acer Predator Helios Neo 16 i9-14900HX/32/2TB/4070/240Hz

Yesterday Microsoft offered me to upgrade to 24H2, which I did.

The system works great and faster than 23H2, however, today I've noticed that CPU (14900HX) is abnormally hot while idle. The temperatures are around 90°C. Fans are on auto, PredatorSense app is set to Balance. Both PredatorSense and Aida64 confirms this temperature.

Now I have to turn fans to max to bring temperature down, but this model is super-noisy so I cannot keep it like this all the time.

Does anyone else also noticed this behavior after Windows update? Or maybe you have the same problem with other systems?

Ok, I found the reason.

Looks like some bugged Custom power plan that somehow appeared in my Win11 installation. Called "Custom plan 1" and I'm sure I didn't create it.

I've changed it to "balance" power plan just for the test and this "Custom plan 1" simply disappeared! I have no other power plans currently.

Most importantly, at last I see my CPU behaving adequately, it adjust frequencies as it should, ranging from around 800 Mhz.

Thank to everyone who tried to help. Looks like some Windows glitch unrelated to the hardware.

^Nope, already tried it. It looks like there is something hard coded, as CPU frequency and temps remains the same, and fans also are working in the same range (which is adequate for that temperature).

In the same time, now I have less than 60C in Windows.

Yeah. Sounds that way. Good to know. Thanks.

Also remember that not installing the Intel® DPTF / DTT component can prevent the system from:

improve battery life;
performing Thermal management correctly;
prevent the correct use of Adaptive Performance modes;
optimize performance for CPU and iGPU dynamically.

Bold emphasis sounds like a double-negative. So does that mean installing it can???😀:

Dear sirs,

I'm glad you're having further discussion here, but I'm even more happy with the current numbers of my fixed system 😍

JackE

Well that looks more like it for an idling CPU. What happens when you fire up the GPU?

Faust

^After idling at 90C this is quite an achievement, I would say.

I'm not playing games without fans on Max. So it never hits 90 either.

so glad you seem to have sorted out your issue. ive had no problems with my machine so far (touch wood) its been a nice quiet machine and very fast. i hope you continue to have good temps with everything. i came back here to see if you had the fan speeds on auto. seems all is good now though for you.
