Acer Neo 16 i9 14900HX locked BIOS, overheating, poor thermals and performance throttling?

I know this has been brought up a million times, but for good reason... WHY in God's name are we locked out of all of the useful BIOS config options?

I have the Neo 16 i9 14900HX with the 4070. This thing run incredibly hot at almost all times. The only time it isn't is if I'm not doing anything at all on it.

Today I had nothing other than Steam open downloading a game and my temperature was at 90c+ This is unacceptable when you take into account that if we had the option to undervolt our processors, we could easily lower our temps without much issue. When playing games, I'm almost constantly thermal throttled hitting 100c. This leads to lower performance. This can be proven when running benchmarks. My Cinebench r23 score is a good 5,000 points below what others are getting with the same specifications but with a laptop from other manufacturers.

Why is it that Acer insists on locking it (and please don't give me the excuse that the 14900HX is locked and can't be OC/UV) when other manufacturers like MSI, ASUS, and Lenovo (to name a few) all allow users to undervolt this exact CPU?

We pay over a thousand (some 2-3k) dollars and are locked out of some very helpful and important features. Don't even get me started on Acer locking the XMP profiles for RAM too.

I feel disrespected as a consumer and plan on returning this laptop in favor of one that respects consumers freedom to adjust THEIR laptop.

You can say that you've "optimized" the experience and it is the way it is intended on being used, but why is subpar thermals and performance considered "optimized" or "intended" by Acer?

Then there's the other argument that customers could harm their laptop, while this could be true, you could just put a warning message notifying users and having them accept the risk. It feels like we are being limited for no reason.

I look forward to hearing what a CS representative has to say, because the online chat was no help at all. If its more of the run around, I'm shipping this hotplate back and grabbing something else from somebody else.

    Actually it's same for most of laptop manufactures. Only rare laptops have advanced bios unlocked as

    • Even experienced users can make mistakes or misjudge safe limits when adjusting settings. Manufacturers prioritize safety and stability, which can lead to system failures or hardware damage.
    • If manufacturers unlock advanced features, they may face increased support requests from users who encounter issues after making changes. This could lead to liability concerns if users damage their hardware.

    As for your issue this is intel fault. Intel has identified significant instability issues affecting its 13th and 14th Generation Core processors, primarily linked to elevated operating voltages. This problem arises from a faulty microcode algorithm that causes the CPUs to request higher voltage levels than necessary, leading to system crashes and potential long-term damage to the processors.

    Intel has committed to releasing a microcode patch aimed at resolving these voltage discrepancies.

    Intel and acer has updated microcodes through bios version. You have to update your bios to latest version. Do it carefully.

    Thank you for at least providing a different resolution, but I have already updated my BIOS to v1.16 (the latest according to Acer's website) which has Microcode 129. According to HWINFO. It has not alleviated the issue. THERE IS ALSO A 12B microcode, but Acer hasn't pushed that still.

    I didn't claim that the issue is Acers fault. I know intel released unstable chips for the 13-14th version. And as mentioned, I know of the increased risk when undervolting and overlooking, but contrary to your statement, this is not limited to advanced laptops.

    You can undervolt or overlock a Legion 5i or even a Legion LOQ (both of these are in a similar space price and performance-wise to the Helios Neo 16) provided they come with an HX chip. Heck, I could undervolt my HP laptop when I had one.

    May I also ask why XMP profiles have been disabled from the BIOS? Just a major disappointment that so much is locked out - especially when the solution to my problem is right there, but am artificially locked out of the ability to fix it and am at the mercy of Acer to fix the issue, which I know is not going to happen.

    Both the Acer Nitro and Predator series have good cooling systems. If you are still experiencing heating issues after updating the BIOS, I think you should consider returning and replacing this laptop as return window is open till 7 days.

    Yeah, I believe I will be returning this and going with another manufacturer that isn't so locked down. Most likely Lenovo.

    I have. The LOQ, 5i, and 7 allows for it (for now, at least).

    The PHN16-72 with its 14th Gen Intel i9-14-900HX cpu is designed to work at high temps up to 110°C, your laptop running 90°C-100°C is normal to run monetarily, make sure you have the last bios v1.16 installed for the Intel fix for the MCU to 0x129 microcode, that Intel had cpu problems with the 14th Gen cpu's, also make sure you have all the Win-11 24H2 updates to the last OS build: 26100.3476 and play all supported games through the NVidia GeForce Experience software and also update to the last RTX4060 gpu game ready driver through this software.

    Also, buy a good gaming multi fan tablet cooler as that also helps in crossflow ventilation and overall reduction in heat of these laptops. Doing all this will keep your laptop cooler and make it perform in gaming also. that is what I've done with my PHN16-71 13th Gen i5-13500HX cpu / RTX4050 / 64GB DDR5-4800MT/s CL40 RAM / Samsung 1TB 990 Pro NVMe M.2 boot drive and slave drive laptop, that works great in gaming, editing and all aspects that I use this laptop for.

    Higher temps are not an issue since the i9 14900hx is made to tolerate, the issue is that games are crashing when using Performance mode or Turbo mode with "Access Violation Error", sometimes it restarts directly, and sometimes BSOD.

    I tried many solutions, only thing worked is setting the power mode in Windows 11 to Best Power Efficieny, which drastically lowered CPU temps from above 90 degrees, to around 70s and stopped the errors happening.
