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?

[Edited the thread to add model name and issue detail to the title]

    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.

    Check TaskMgr to see if you can spot the process(es) consuming so much CPU time at idle.

    same any fix?

    Mihraj Gotta know what processes are consuming so much CPU time before we can make an educated guess on the fix. So check TaskMgr to see if you can spot the process(es) consuming so much CPU time at idle.

    The problem is - there is none.

    Do you mean no problem of the CPU getting hot anymore or no processors running in the background? If the latter, dozens of Windows system and related processes must be running in the background even while Windows is idling with no user initiated processes or apps running in the foreground.

    Of course I mean the later. And of course there are dozens of Windows processes. None of them is irregular and none uses more CPU power than it should, i.e. 0-5%.

  • JackE

    Yes, but then how many are actively running at greater than 0% that would cumulatively add up to the total percentage needed to account for those high temperatures. If they don't add up, then this might suggest a coolant leak or air blockage has occurred in the CPU's thermal module.

    I bought this exact computer recently and I dont unfortunately have access to it till Christmas. But I would suggest looking at the windows power profile and seeing what the minimum and maximum cpu percentage is. It also seems to me that windows may have broken predator sense and the pc is operating at maximum performance all the time. I think if you bring up the process manager on one of the tabs you can see the percentage use on the processor and see if idling is a problem. I suggest you maybe uninstall and reinstall predator sense in the first instance and see what that does. The other thing you could do is make a new windows profile and see if the machine still gets as hot on the other profile if it doesn't then it means that something on your profile is constantly taxing the pc. Hope this helps my answers for now can only be very generic. I hope you sort this out. Especially as I may be facing that same problem in a week or so. Let me know how it goes

    I'll look further into this.

    And yesm the Acer support for this particular laptop is awful. Not at all what I've expected from Acer (I have 3 more laptops from them in my family). PredatorSense is seriously outdated. I've already tried updating it to the newest version, but it is currently incompatible with our model and updating it created a whole bunch of problems, so I had to roll back.

    I see there is new OFFICIAL version, 5.0.1429. I will try it later today.

    The PHN16-72 laptop is designed to run hot and at 90C temp this laptop even at idle is not a high temp. The Acer tested temps at idle and at 90C the laptops fans should be spinning at between 2300 / 2600 rpm at 34db and at 110C the fans were tested in turbo mode at 5200 / 5800rpm at 54db, so that is what you should expect from this laptop. Its OS shutdown is at 110C so you can never ever damage this laptop as the Intel 14th Gen cpu’s are know to overheat also.

    I suggest that you buy a good gaming tablet laptop cooler and sit this laptop on top of that and not put the laptop flat on a desk, I’m using one with my Nitro laptop especially in my neck of the woods where its summer and todays temp were close to 100F. Good luck and hope this helps you out some more.

    Yes, I have a laptop cooler and I never use my laptop on any other surface even if I dont always turn the cooler on.

    Nevertheless, I disagree that 90 is normal. Because I clearly see it can be idle at 60-70 without problem, those spikes at 90 are absolutely random and I cannot see what causes them.

    I will report back after PredatorSense update.

    90°C is too hot for no user controlled processes running. So what problems were you having with the old PredatorSense that you thought a newer version would fix?

    I had none before upgrade to 24h2. And, as Rammstein said, maybe current/previous (March) version is broken in 24h2 and forces CPU to work at max frequencies for no good reason.

    If you're talking about my previous attempt to update - I didn't do it on purpose, Microsoft Store just updated it along with other apps. I've noticed it after problems began and then rolled back and made sure Microsoft Store won't update it again.

    5.0.1429 version, however, is provided by Acer itself and specifically for this laptop, so it should be good.

    5.0.1429 version works correctly, all functions are present.

    And I think I finally see the reason - this is indeed CPU frequency. It doesn't drop below 4000 (and it seems to mostly be at >5000, at least when PredatorSense or CPU-Z is monitoring), at least I've never seen it below this. I've checked the power plan - the minimum for CPU is set to 5% both plugged in and battery. But I believe power plan doesn't do much - in this system everything is governed by PredatorSense.

    Maybe I just have to uninstall it altogether.

    OK. Reasons why I try to avoid Microsoft accounts, their store. Yes, it'd be interesting to see what happens if you uninstalled it.

    Hi again it seems to me from whats been said that predator sense is not telling the laptop to change the processor state. I think this is especially likely seeing as Windows has seen to install random updates. When I get my pc I'm going to disable automatic driver updates I think. Please let me know if uninstalling predator sense makes a difference but I also wanted to alert you to a youtube post I have seen regarding fixing predator sense that might work for you. I hope link posting is allowed but here we go https://youtu.be/TaGjKTwbysM?feature=shared it seems like the installer is not installing all the dependencies of the program and therefore the predator app may not be controlling the processor state correctly. Please try this and see what your findings are. I look forward to helping you more when I get access to my own system.

    ^Thanks. Weird, but I will try it tonight.

    But uh, his CPU is around 98 degrees, not sure if his method really worked for him :D

  • Faust
    Faust Member Posts: 36 Devotee WiFi Icon

    So I've tried the method from the video above.

    It changed absolutely nothing. CPU still won't go below 4000.

    Has this been tried yet to see what happens?
