Hi,

I recently bought the new helios 16 neo with the latest 14900hx cpu, like the previous model it still runs hot as hell. 90-100c in turbo mode, 85-90 in performance mode(still hit 100 sometimes). The bad thing is you cant change processor state to 99%, u cant unlock cpu undervolting in bios either. fn+tab dont work either with the latest. Hitting 100 and above seems fine some say because its meant to handle it..but sure it will kill the chip longterm..

Is there someone who have find some settings that work for the latest version? :(

    There are no mods for these laptops as they are made to run in those temp ranges, if you have any high temp laptop turning off issues contact Acer as that should not be happening, contact Acer in your country and work out a solution with their technical support. Good luck.

    Hi Bro/Sis, I also have the same model. Apparently it is supposed to be hot most of the time (based on what people said online and the fact that the keyboard doesn't get really hot even when cpu is 100c.) But I would still prefer my laptop cool. So, I did read some things about turning turbo boost off in BIOS (which I did not manage to do) but, I also read that it is not suggested for people who play games. Anyway, what I do to reduce temperature is put fan mode on custom and increase it manually. Don't know if doing so is bad for the device but it sure does help. Please let me know if you find better ways of cooling. good luck.

    I am using Core Temperature (free app) to log the temperature, and have been observing that BSOD is getting more common, sometimes even when I am not doing anything. am a photographer, using Lightroom. Even on low load, it hit 100 degrees (above 80 to 100 often), and the load is always showing below 20%.

    My acer Tech seems to blame it on the 3rd party ram and NVME (Samsung Evo Plus) for the crashes, seemingly saying that if all these BSOD are due to these, my Acer warranty will be void. Later when I point out that it's been running hot (show video proofs of rendering and non rendering), he tries to say there's many other users saying Lightroom is to blame, and it's mentioned often in online forums.

    Everything seems not to be Acer's fault -_-

    I got a feeling this is going to be my first and last gaming laptop from Acer. Didn't have this BSOD issue from Asus Gaming series since their 10th Gen Intel and 12th Gen. Thought I give Acer a try and it's even heavier for a smaller screen (16" at 2.9kg while Asus is only 2.2 kg at 17.3"), not to mention about Acer's monster adaptor weight 1.2 kg for 330W, which throttles the performance for overheating anyway.

    I hope they come up with another BIOS update soon to limit the power, I will gladly choose slightly lower performance over BSODs which throttles anyway, and it will cause so much data corruption.

    After 3 years warranty, will change out of it with my extended warranty as the BSOD is unsolvable. Just poor Harvey Norman who chose to take up their product for coverage.

    Hey, I had the exact same overheating issue with my PHN16-71 (i9-13900HX) and I found a solution that actually works without undervolting or BIOS hacks.

    Just go into Predator Sense and enable Turbo mode permanently. Even though it sounds counterintuitive, in Turbo mode the fans stay active constantly, even at low loads. That alone keeps the CPU from jumping to 90–100°C for no reason.

    In my case, idle temps dropped from 90°C to around 60–67°C, and even the hot zone near the Numpad got much cooler. CPU clock also stays lower when idle — I’ve seen it drop to 1.5–2.2 GHz, which never happened in Balanced or Performance.

    It’s stable, quiet enough, and works even with bad electricity (like in student dorms). Try it — let me know if it helps.

    The Predator Helios 16 Neo, particularly models with the 14900HX CPU, can experience high CPU temperatures, sometimes reaching 90-100°C during normal use, especially under heavy load like gaming. This is within the CPU's operational range, but prolonged exposure to such high temperatures can potentially impact long-term performance. Some users report on Acer Community that disabling the dedicated graphics card for a while can help reduce temps.

    Here's a breakdown of the issue and potential solutions:
    1. Understanding Normal Temperatures:
    The CPU in the Helios 16 Neo is designed to operate up to 100°C, but sustained high temperatures can lead to thermal throttling and impact performance.
    While 90-100°C might be normal under heavy load, temperatures consistently in this range, or even higher, could indicate a problem or warrant further investigation.

    2. Causes of Overheating:
    Poor Ventilation:
    Insufficient airflow around the laptop can trap hot air, raising the CPU temperature.
    Dust Buildup:
    Dust accumulation on fans and vents can restrict airflow and impede cooling.
    Fan Problems:
    Failing or malfunctioning cooling fans may not be able to dissipate heat effectively.
    Thermal Paste Issues:
    Poorly applied or dried-out thermal paste can hinder heat transfer between the CPU and cooler.
    Power Settings:
    High-performance power modes can push the CPU to its limits, leading to higher temperatures.

    3. Solutions and Troubleshooting:
    Improve Ventilation:
    Use a laptop stand or elevate the laptop to allow for better airflow underneath.
    Ensure the laptop is placed on a hard, flat surface, not a soft surface like a bed or lap.
    Clean Dust Buildup:
    Regularly clean dust from the air vents and fans using compressed air.
    Check Fan Functionality:
    Ensure all fans are working correctly and not making unusual noises.
    Adjust Power Settings:
    Consider using a balanced or power-saving power plan in Windows.
    Explore options to limit the CPU's TDP (Thermal Design Power).

    Use a Cooling Pad:
    A cooling pad with fans can help dissipate heat from the laptop's underside.
    Monitor Temperatures:
    Use tools like Predator Sense or other monitoring software to track CPU and system temperatures.
    Consult Acer Support:
    If temperatures remain high or you experience other issues, contact Acer support for assistance.
    Repaste the CPU (Advanced):
    If you're comfortable, consider reapplying thermal paste to the CPU, but this requires disassembling the laptop.

    4. Specific Recommendations:
    Check PredatorSense: Review temperatures in PredatorSense, particularly during gaming or other intensive tasks.
    Consider a Cooling Pad: A good cooling pad can make a significant difference in temperature management.
    Don't block vents: Avoid placing the laptop in a position where the vents are blocked.
