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

Jofer · January 2020

I look for similar solution for predator triton 300 model PT315-51
If someone will find a way to manual control fans please post it.

You can create config for your model yourself, it’s very easy

Check CPU temp in PredatorSense and convert it from decimal to hex using this site
https://www.rapidtables.com/convert/number/decimal-to-hex.html

Download and install this app
http://rweverything.com/download/
open menu Go Access - Embedded Controller and find hex value you got on step one
Get number of register where it stored, i.e. number from 1 to 255

Then download profile I uploaded above and change in config app its write register from 219 to what you got

That’s all

I also think you may want just to delete write register for gpu temp or set your own, I’m not sure it’s required, logic of how to define it is the same

I wonder why Acer put awful fan control in every their laptops, do they have students or low quality engineers responsible for cooling? They really don’t care about quality of what they issue

This method may be applicable to every Acer model unless they update temp register too often

And even with this interval sometime EC can write its value, if you set 0 rpm in full silence can you here periodically that fan try to start?

I haven't noticed fans start during brief testing, though I have hdd so it's possible fans start can't be heard because of hdd noise

I found that I can set cpu fan to custom speed as low as 600 rpm thats so cool)

and interesting thing is that after reboot this setting is stored which means they remembered this value somewhere so it can be investigated where it is for even better fan control

I guess to set both fans to 1000 rpm until 55C this will cover most of the cases on low load and will be really inaudible, you can hear it only with ear near the vent
Aftr 55C it can increased proportionally

hi
for anyone install this fix from @belik
did you notice audio glitch like this one

https://www.youtube.com/watch?v=iU2MGBpwzck&feature=youtu.be

I am asking because it becomes more noticeable after I installed it

Yes I have the same popping sound and depending on the videos, sometimes it's very pronounced like every second, and sometimes it's a lot rarer. Haven't had time to work on it but did anyone try to go to an older driver or something else?

Good news

we can increase poll interval from 100 to 1000 ms as I didn’t find any attempts of fans to start. It will reduce load to cpu and system in overall in around 10 times
Now this background service takes 0% of cpu load and rarely increased to 0.2% which is very good

I also removed writing to the gpu register and didn’t find any impact so only cpu register must be enough

And finally I tried several automatic scenarios of fan speed depending on cpu temp and it all works like a charm exactly how it was setup

So now the last thing left is to define what custom fan curve table would be better for users and setup it in the app

Well there is one showstopper here and am not sure that it will be passed so I am going to post what we have now so that those findings won’t vanish
I asked the question to moderator of this community hopefully he will forward it to Acer engineer and get feedback. Without this answer NBFC will not work as it should.

Before you start, be aware that you are responsible for PC temperatures coz if you set fans to constant speed system wont be able to take control over

Also if anything goes wrong, don’t worry. You need to reset bios and EC (embedded controller responsible for fan control), to do it turn the PC off and then press power button for 12 seconds

Here is the fan curve table system uses to control fans

There is also must be one record in the beginning with 21C, below 21C fans have 0 rpm

Unfortunately we don’t know where this table stored in, we can’t find it neither in bios or EC so we can’t change this table
And what our approach is that we overwrite value in CPU temperature register so EC thinks that temperature is different and set fans according to the table above
But this is a register used only by PredatorSense so wrong temperature will be reported only in PredatorSense. Other apps like hwinfo, aida64, Intel xtu, NBFCetc use another sensor and you can check it there

So here is the NBFC profile it’s not even mine and you can adjust it as you want and maybe even create custom fan curve. It suites for PH315-52 and PH317-53
https://www104.zippyshare.com/v/3PgmW8i6/file.html

CPU temp sensor is 219 register, GPU 221
CPU fan read sensor 112 register, GPU 92

The main issue of this method is that we both, system and NBFC, try to overwrite the same register and struggling for that. So this method is not reliable and only for testing purpose.
For proper use we need to switch EC to manual mode and for that we must know where this register is, this is the question I wait the answer for.

Don't worry @tecBart use this one with slight improvements
https://www.sendspace.com/file/bjgbkr

You can adjust it to your own custom fan curve just in few clicks

Could you help out with some more details on how to set up the fan curve in NBFC?
Thanks

Tikisin he already explained in the post above plus you even have a conf to start with

HI I have Predator PH315-52
I tried notebookfan control. Its look its working but after disabled my battery dont wanna charge

only discharging but I have plugged AC adapter... When I remove Ac adapter Notebook show 96% and when I put to laptop battery show 100%.
I dont know why but I must "Battery Reset" from Acer GUIDE. Its work and charging battery works now. But I am little sceptics.
Can be problem with registry ? I thinking and my theory is not PH315-52 not same and did my problem because registry after diable NOTEBOOK FAN CONTROL.
How can I solve this and make my config ?
Thx for help

I tried your config but after disable battery dont wanna charge

only discharging

and I must do RESET BATERY from Acer guide.
My Notebook is Predator PH315-52. Fan control work but after disable this feature battery cant charge

Battery discharge when I unplugged AC Adapter...

And after I pluged AC adapter battery show 100%, but after unplugged battery showe 96% and discharging and charging battery dont work

Do I have to do this every time I use the Notebook FanControl?

Do you always do it like that? Is this a general problem or just mine?

Resetting it by holding down the button for 15 seconds as per Acer's instructions will reset the BIOS, battery and everything as a chip to take care of RPM fans. It is so ?

So I have to do this every time I want my computer to charge after using a "Notebook Fan Control" program?

belik · January 2020

No

No

And your laptop charging normally ?
I must in
1. start notebook fan control.
2. select config and start
3. turn off computer and do it restart when I press 15s power button and this works normally you said or not?
Tell me guide how

Thank you

belik · January 2020

Uninstall NBFC, turn off laptop, press power button for 12 sec

VeganCzech · January 2020

I do this and charging working but my question is... Can I regular fan without problem with charging? You have same problem or not?
So I must do this any time when I wanna charge my laptop in trip ?
