Unfortunately we know that most Gamer Notebooks have temperature issues with the factory settings which is absurd. As we have to live with this, the best way to solve the problem is to undervolt and underclock.

In the image below I made a comparison between two settings in Fortnite.

Default: CPU clock with no restriction running at ~3.9GHz and average temp 90º, GPU core clock ~1.6GHz and average temp 72º.

Custom: CPU clock limited to 3.5GHz and average temp 68º, GPU clock limited to 1.4GHz and voltage limited to 0.7v and average temp 62º.

Regarding performance, the difference is almost imperceptible, but the gain in temperature reduction is absurd.

Yes thats because intel cpus heat up like crazy and throttle like hell when on turbo boost speeds and to me the best solution its still to repaste it with kryonaut or similar and then optimize and undervol on top of it and all the issues are completely gone also the manufacturers will never limit anything because they could be sued for it as if someone would complain why the cpus do not hit turbo boost speeds but hands up to acer that was the first manufacturer to undervolt some earlier predators on stock but thats alwasy a risk of getting sued by someone so the end user is free to do whatever they want/need to to get it working as they wish thats my personal view one thing all manufaturers should improve would be stop using rubbish thermal paste and start to use proper paste like for ex kryonaut even if they had to charge a bit more for it would be really worth it and avoid 99% of the thermal issues complaints

Latest Fix:

Intel 8th Gen: BIOS 1.15 has been released to fix the screen flickering on the Intel 8th Generation laptop. 

1. Common Information (CPU, GPU, Temperature Specifics)

Temperatures & Solutions

If temperatures reach the following (under intense situations), these are your options:

97-100C (Throttling below base clock speed)

• Contact Acer for repair (they will re-paste your CPU/GPU)
• Re-paste your CPU and GPU yourself (not advisable due to warranty complications)

90-96C (CPU turns off Turbo at 90C)

• Using Predator Sense, turn fans to max speed
• Undervolt the CPU (guide below)
• Purchase a laptop cooling pad (paid less than $15)
• Limit the CPU performance via Windows Battery Options
• Re-paste your CPU and GPU yourself (not advisable due to warranty complications)

~89C

• If temperatures never go above 89C, you do not have to worry about CPU throttling. 

CPU Undervolting

If you would like to learn more about modifications and tweaks to our Helios and Predator laptops, please take a look at the Facebook group in the credits.

Thermal Pasting Guide

(I suggest sending it to Acer support first.)

If you are encountering high temperatures and would like to re-paste your CPU yourself, read below.

• I recommend a nonmetal-based thermal paste with no electrical conductivity, such as Arctic MX-4.
• Video Guide: 

*Note* 
Re-pasting your CPU will void warranty if you damage something, so proceed at your own risk.

GPU Temperature Information

It seems that it is rarely the GPU that is the problem when it comes to overheating in these laptops. However, the GPU still has some limits that you should keep your eye on.

We only have estimations for the GPU limits from feedback on the forum. It seems that the GPU will near maximum, or maximum performance so long as the temperatures stay below 80C. If temperatures are above this number, these are what can be done:

• Using Predator Sense, turn fans on max speed
• Turn down game settings (only temporary/crappy solution, skip to next)
• Re-paste the CPU and GPU (either via Acer Support or yourself)

2. FPS Drops/Lag

Desktop Right-Click Lag

This problem is generally caused by the Intel Graphics Control Panel Desktop Context Menu option. To fix this, we will need to disable the Intel Graphics Control Panel in the desktop context menu. If you have already tried updating the Intel drivers via Device manager or installing the drivers from Acer's web site, follow these steps.

Steps:

1. The easiest way to disable this is using the program 'ShellExView' that be found at: http://www.nirsoft.net/utils/shexview.html
2. After downloading and launching the program, you will need to find the two items to disable. These both are under the Extension Name 'TheDesktopContextMenu Class' with the description 'igfxDTCM Mod' as shown in the screen shot.
   
3. Disable these two items.
4. Restart your computer.
5. Give feedback to let us know if this solved the problem.

Possible FPS Drop Solutions

These are solutions you can do to either: stop FPS drops, or improve FPS/Performance. Do one step and test until your FPS drops stop. 
Post below which step fixed the FPS drops.

1. Go to Windows Settings > Gaming, and disable Game bar, Game DVR, and Game Mode.
2. Update NVIDIA Drivers, and Uninstall GeForce Experience.
3. Update your BIOS to the latest version.
4. Update the Intel Graphics adapters to latest by: right-clicking the start menu, opening Device Menu, expand Display Drivers, and right-click the Intel(R) HD and update drivers.
5. Uninstall any 3rd-party screen recording/overlay software.
6. Uninstall any 3rd-party anti-virus software (e.g. Norton, McAfee, etc.) or cleaning/monitoring software (e.g. CCleaner, Glary Utilities, etc.)

Windows Update Caused Crashing

It has been found that when Windows 10 updates, it installs the latest drivers in the Windows Update Database. These drivers seems to be causing some issues.

A possible fix is reinstalling all drivers from Acer's web sitefor your device.

Windows Update Failure

The biggest reason Windows updates fail is due to an anti-virus. If your laptop fails to update. Uninstall any anti-virus you have on your machine, and retry the update.

3. Battery Gaming

It is not advisable to game while on battery for multiple reasons: 

• Laptop is self-throttled; 
• Degradation of battery; 
• Poor game play.

The battery throttle settings can be found/changed in the GeForce Experience Settings. As stated above, it is not advisable to game on battery.

4. Predator Sense Information & Overclocking

Predator Sense has a habit of not working correctly with the new updates to Windows 10. There are some things that you can try to get Predator Sense working again.

1. Uninstall Predator Sense, restart your laptop, and reinstall Predator Sense from your laptop's support page.
2. Right-click the Predator Sense icon and run the 'Compatibility troubleshooter.'
3. Uninstall or shut down MSI Afterburner if installed.
4. Try re-enabling hibernation/hyberfil.sys if you disabled it when GPU shows idle when being used.

@Red-Sand has found a way to enable the overclocking feature on the G3-571.

***Warning***
Will cause the laptop to run hotter. Do so at your own risk. 

You can follow the video to manually enable this, or you can download the zip file from the description and go as follows:
1. Download file
2. Unzip contents
3. Run preferred .bat file as administrator
4. Restart Predator Sense



*SUBSCRIBE*

I will explain further. What this does is change the device that Predator Sense reads in the registry. Red-Sand uses the PH317 in his video. The batch file I created uses the G3-572. Both work.

5. Sound Modifications (EqualizerAPO)

EqualizerAPO

-*-WARNING - READ BEFORE CHANGING PREAMP-*-
Always keep volume at middle range (50%) when changing the Preamp, as high Preamp could damage your speakers, headphones, earbuds and/or ears. By default, the Preamp is lowered to -3. Increasing it until +3 is relatively safe but be cautious of increasing it more than that without taking the previous precautions mentioned. High Preamp may also distort sound quality.

-*-The drivers must be reinstalled after every major Windows update.-*-

This is the first posting. Details and screenshots will be added and refined in the future. We will be able to post our own equalizer profiles for best audio settings as well, as we mess with it. The settings are stores in *\EqualizerAPO\config\config.txt.

Basic Device Setup:

1. Make sure the audio device you want to use/modify/test is connected.
2. Download Equalizer APO
a. https://sourceforge.net/projects/equalizerapo/
3. During installation, I set the location to C:\EqualizerAPO because they do not give you desktop shortcuts.
4. After the installation, you will be prompted for which audio devices you wish to use Equalizer APO for. You can choose one, or all. This can be changed later.
5. When you choose the device(s), it may require a restart, and all Windows will disappear.
6. Configuration:
a. To modify the equalizer and Preamp settings, launch C:\EqualizerAPO\Editor.exe
b. To change what devices use Equalizer, launch C:\EqualizerAPO\Configurator.exe

Laptop Speakers (includes headphone jack):

I had some difficulty getting it to change my Helios 300 (G3-571) speakers, but I found out how. Follow below:

1. After Equalizer APO installs, open the Configuration.exe.
2. Highlight Speakers, and check the 'Troubleshooting options' button.
3. Uncheck both 'Use original APO' buttons, and change Install as to 'Install as SFX/EFX (experimental)'
4. Restart and it should work.
5. Feedback is appreciated.

Questions, please let me know.

Frequency Table (to help with tweaking the equalizer):

Sub-Bass - 62Hz and lower
Mid-Bass - 62-125Hz
Upper-Bass - 125-250Hz

Lower-Mid - 250-500Hz
Middle-Mid - 500-1kHz
Upper-Mid - 1k-2kHz

Lower-Treble - 2k-4kHz
Middle-Treble - 4k-8kHz
Upper-Treble - 8kHz and higher

6. Meltdown, Spectre, and Intel ME Vulnerability Information

There are 3 major vulnerabilities that affect our Intel laptops and I will post some information about these issues.

Acer Meltdown/Spectre Link

Meltdown

• On Intel CPUs and any CPU with Speculative Execution (Apple CPUs)
• Meltdown is probably the most serious of the three vulnerabilities. It allows processes to bypass security checks and execute code/read data stored in the CPU's memory.
• Fix: Microsoft Windows patch KB4056892 (OS Build 16299.192 on Windows 10 Version 1709 or later)
• Running Windows without this patch makes your system vulnerable to Meltdown (and some of Spectre).
• To check if you have this update, navigate to Settings > Update & Security > View installed update history. 
• *Note* Some Anti-virus can conflict with the update.
• Refer to Microsoft for more specifics: https://support.microsoft.com/en-us/help/4056892

Spectre

• 99% of CPUs suffer from this vulnerability. Unlike Meltdown, AMD and mobile CPUs are included.
• Refer to Meltdown for getting the patch in Windows.
• BIOS updates mitigate vulnerabilities with Spectre.

Acer Intel ME Link

Intel ME (Intel-SA-00086)

• This vulnerability is different from Meltdown and Spectre. It required a patch from the software Vendor to fix in the form of a BIOS update.
• Acer's information about this update can be found here: https://us.answers.acer.com/app/answers/detail/a_id/51890

So, as I see this thread still running in 2021 that has to mean something. I bought my Acer Predator Helios 300 back in 2018 and it was a very good time, right now, after 3 years of using it, I have to say that I will probably never buy another gaming laptop. When trying to run anything that just remotely resembles a game, my laptop runs hotter than Megan Fox in the first Transformers movie. We're talking here about 98 degrees with max fan speed and a cooling pad set to max. When I just have Firefox open with 8% CPU load it runs over 50 degrees. When running a game CPU and GPU loads aren't even that high something like 30-40% and my laptop is having a meltdown like a teenage girl that got a pimple on her forehead on Prom night. I've already re-pasted my CPU and GPU, undervolted the ever living hell outta my CPU and still results are the same thermal throttling when something more is happening on the screen. I'm at a loss and I would buy a desktop if the bloody GPU's wouldn't require me getting a loan or selling my kidney on the black market.

For what I'm running:

Predator Helios 300

Intel i7-8750H

Nvidia GTX 1060 with 6GB of RAM

DCasualG clean your fans properly repaste it with kryonaut or similar and undervolt/optimize thats the proper solution because only undervolting/optimizing wont do anything if its not properly cleaned/repasted also keep the back lifted 2/3" at all times for a proper airflow

Kiragoa

Any nvme ssd heatsink compatible for predator helios 300 ph315-54? Or just use prebuilt thermal pad?, TIA

Kiragoa m.2 ssd heatsinks are only compatible with desktops they will not fit on gaming laptops there is not enough space

I have found that my Predator Helios 300 hits 97c CPU temp only while charging and playing games. If I play those same games on battery power alone, temps will only hit 60c. My question is, can I run my Helios 300 without the battery and solely AC power?

No. Battery is meant to complement the AC Adaptor during GPU intensive tasks.

xapim

@apkshu no you cant remove the battery the laptop will never work properly if you do so and make sure youre always on AC while gaming or performing high demanding tasks only use it on battery for really low workloads and on emergency optimize your windows undervolt and if needed repaste it with kryonaut or similar if youre able to without voiding your battery and make user the fans and exit airflow are properly cleaned and the back lifted 2/3" for a proper airflow
