i9 13900hx overheating flags and forcing low memory speeds on Laptop: Helios 16 PH16-71

When I talked about overheating in the helios 16 laptops, I was talking about relatively new laptops. I am aware that cooling pastes can degrade over time. However, since my laptop has liquid metal installed, I am not confident in changing the cooling paste on this. I have already cleaned the fans once after the warranty ran out however I do not see any improvement on temps.

I will try changing the thermal paste through acer repair. Thanks.

"When I talked about overheating in the helios 16 laptops, I was talking about relatively new laptops." This sentence means "Acer helios 16 laptops in general have overheating issues even when they're new" not "My laptop is new".

Hope that cleared things up.

A quick search on google "Acer helios new overheating" will lead you to posts such as :

However, if your solution is just to change thermal paste, then no I don't need instructions.

As I asked before, I'd like to be made aware of a power-saving event that forces my memory to go down to 2000-3000 Mhz for 2-3 seconds at a time. If yes, then can I stop that from happening?

This is the only answer I am looking for.

Just to update for people who will be looking at the thread in the future:

Went and got my laptop re-pasted at a local acer predator shop. They serviced the laptop and repasted it.

The repaste is working as idle temperatures have fallen to around 50°c from 70-80°c.

Did it solve my issue? Nope.

The laptop still spikes massively in temperatures during any sort of gameplay or heavy duty tasks.

If I cannot use a tool without it failing and slowing down, it's not a good tool to begin with.

P-core 2 and 3 for me still go up to 98-100°c. This is absolutely not normal in any case. Let alone playing apex legends on all low settings. This is a simple task that an i5 can do let alone the i9 13900hx.

Possible solutions I see are:

1. Undervolting.
2. Sending the laptop back to acer to get it looked at by a professional.

Option 1 is completely impossible as I have found out that accessing the advanced BIOS to enable under-volting for the CPU is not possible on the helios 16 (non-neo) (PH-16/PH-18 series)

If you have a helios neo (PHN-16) or any other acer then you can hold fn+tab before turning the laptop on and then go into the advanced BIOS with f2 when the laptop screen turns on.

If you have a non-neo (PH-16/PH-18 series) version and have successfully opened the advanced BIOS it'd be of great help if you could let me know how, as I have not been able to do replicate the fn+tab method on mine.

As for option 2 I have already reached out to Acer India and I am waiting for their response. I hope they can make heads or tails about this issue because if they can't then my last option will be to buy a new laptop which is not easy in India due to sky-high taxes. I also lose a lot of money on the laptop I already have if I have to sell or exchange it.

Why did Acer lock the undervolting options on a HX series CPU which is marketed as unlocked? Every other manufacturer seems to let you customize the voltage and clock speeds. Acer itself allowed the same thing on previous generation HX CPUs and neo models.

All in all, I hope my laptop does not fail as all my work is on it. I do regret buying Acer even if my previous helios served me well. I can only hope I get a decent resolution from Acer's official support.

After much deliberation by multiple people and trying out various solutions, My laptop seems to be on it's last legs.

Now, since I have hard evidence of the laptop malfunctioning while being used well below it's maximum capacity, will Acer do anything to help me out with a repair or replacement? Or is this laptop as good as e-waste?

Acer's official support in India also refuses to answer.

Is there any way I can get this done without resorting to consumer court?
