Helios 300 PH317-53-72P5 rtx 2060 fan stopping

belik · September 2019

Fan costs few dollars so I don't think anyone will replace whole laptop instead of just 5-10 dollars

Even more, with system temperature under 33C in idle this model will last much longer than other ones where temperatures is around 50C

i play game like assassin, the division 2...
with cooler pad and cpu underclock to 1500mhz and fps limit to 35fps
my cpu and gpu temp never reach 50C

for fan control on idle to get 0 rpm, last time i send message to predatorgaming twitter for any news. they don’t said it’s impossible they said no update yet

they did it on purpose to wear out the fans faster and make us change the PC

Thats really not accurate the fans are probably the cheapest hardware part in the whole laptop

So 3 months passsed and result is zero. I don’t see any signs that this issue was taken and work in progress.
Why Acer support is so terrible? Do they care only about selling new toys and then forget their customers?

I also have Y540 as my second laptop and this laptop has cooling setup absolutely right. Fans stopped until temp 50-55C so in browsing it is full passive keeping temperatures at 45C. Y540 is a way better laptop in this and any other aspects.

Have you actually contacted Acer support with the issue, or just here on the community boards?

I'm also experiencing this issue, too noisy for idle. Interestingly, it seems there was silent mode for previous generation, mentioned here https://www.google.com/url?sa=i&source=web&cd=&ved=2ahUKEwi2yfPOuc_lAhUlmYsKHdbnBPkQjhx6BAgBEAI&url=https://community.acer.com/en/discussion/561557/little-to-no-control-of-fan-speed-helios-300&psig=AOvVaw2kO9CI-z-w0Z60T-Etwytq&ust=1572918877698748

I had contacted support, waiting for response

Stuont · November 2019

Support answered that the only thing they can offer is laptop diagnostics...
No point for diagnostics of something by design. Now I think that was my poor choice to buy Acer laptop

Hey there, I think I found a solution

First, I replaced thermopads and thermopaste everywhere so it could help in lower temperature and then ..
Well as you know on idle fans run at 1680/2160 cpu/gpu, cpu is plastic fan and gpu is aeroblade
And it turned out that all the noise comes from aeroblade. Not only becoz it runs at higher rpm but also those blades ornate shape produce more noise

So I've got another one plastic delta fan the same as standard and results are just wonderful

Now my system run at 30/27 degree on idle (i e when I leave windows in saver mode with cpu utilization 1%)

and both fans run at the same 1680

And this 500 rpm lower speed in combination with normal plastic blades make really huge difference. Now sitting in the silent room you can barely hear the fans and it is absolutely not annoying. I'm very happy with achieved results

And here is Helios with two proper plastic fans

xapim · November 2019

@belik i always said the noise was due to the aeroblade 4th gen owl shaped fans this is a solution but not for everyone as most ppl have warranty stickers and they will void them if they disassemble it and i doubt acer would swap the fans if they asked to

also just for everyone to be aware it requires repasting-it with a proper thermal paste (as always i recommend kryonaut or similar if your one of those who is going for it) as i sad this is a great solution but not for all those ones who cant disassemble it have to just stick with what they
have

Stuont as i already said many times theres nothing wrong with the laptop acer will not do anything ever because theres nothing wrong if youre one of the lucky ones who can disassemble it a bit of modding never hurt anyone

belik · November 2019

@xapim well technically you can replace fan without touching cooling system, you can even keep factory tap intact coz you may unscrew top of the fan case and attach to new one

And about temps, I myself replaced thermopads and applied kryonat on cpu/gpu but so far results are not too good, it is still similar to what I see in reviews

For combined stress load cpu+gpu, fans on auto run at 4000 rpm and temps 90C cpu and 80C gpu, with coolerboost enabled they spin 5000 rpm and temps 84C cpu and 77C gpu

I expected much better temps considering factory undervolting, don't know what to do next

@belik where can i find the plastic fan?

Hey, you can ask in local Acer authorized repair shops or buy online or ask here in forum for a contact to buy spare part
What you need is NS85C06 and it should cost around 20 dollars I believe

Regarding the level of noise I can confirm once more that when your both fans at 1680 and laptop is on table just near you in quiet room you will barely hear it you need actually to put ears close to vents so it’s very very quiet

thank you
I just install it yesterday, as you said it was very quiet on battery, but as soon as I connect the AC adapter it start spinning + 2500 rpm and still annoying even though I only run chrome

It all related to cpu temperatures but to change this relation isn’t possible fo awhile

when you are on battery, your cpu must be below 45C and thus both fans run at 1680

when on ac, you have another power profile and when cpu exceeds 45C then fans started at 2000, exceeds 53C and run at 2300, for the range between 53 and 61C they are on 2600

So you may want to adjust power profile, to restrict cpu to run so aggressively or repaste

Happy New Year everyone awaiting!

Solution is coming

In full passive mode, i.e. both fans stopped, plugged on AC I have 53C on CPU
And this is on non-optimized Windows with CPU utilization 5-10% and CPU freq 3-3.5MHz

On battery, CPU power drops significantly and I have around 45C on CPU in full passive silent mode

Very impressive

It is custom bios, right?

belik · January 2020

Nope you don’t need to unlock bios
It’s purely software method through the third party app called NBFC

It’s far from comfortable use yet but I will work on it

In notebookfancontrol you must select your laptop models. I don’t find ph317 53.
how you do that?
thank

belik · January 2020

@Jhjh6980 NBFC is like universal framework which allows to read and write registers to embeeded controller responsible for fan control
But for new models you need to create config from scratch
There is good news that by this method it's already possible to read and write but still it works in the way which is not fully enjoyable
Need more time

When it fully work, you will add this new models to the software?
