[Experimental] Manual Fan Control

[seerge]

Hello fellow community,

Recently I have discovered a way to directly set fan speed in percentage points for each fan individually.
It uses same method as MyASUS does when runs your "fan testing".

In existing and standard way to set a "custom" fan curve - fan behavior would be still handled by BIOS and follow it's internal algorithm. This BIOS algorithm is different for different models, sometimes includes a very high hysteresis (delays before acting), can override some custom fan behavior, etc.

In "alternative" approach, it's possible to actually literally manually set fan speed every second based on temperature readings.

This build implements "manual" fan control as soon as you check Apply Custom Fan Curve, when you uncheck it - fan behavior will be returned back to BIOS.

Current implementation details

• More precise fan speeds, following custom fan curve as close as possible
• Fan speeds are being updated every second
• CPU and GPU temps are calculated as an average from last 6 seconds (can be set via config)
• CPU fan follows CPU temp, GPU fan follows GPU temp, Mid fan follows CPU temp
• If GPU temp is not available by some reason (for example GPU is disabled or sleeping) - GPU fan will follow CPU temp instead
• If CPU temp is also not available by some reason - fan behavior will be returned back to BIOS defaults
• Minimum fan speed is 20% unless it's set to OFF completely (similar to how BIOS handles this)
• Maximum fan speed is 100%
• Fan speed will follow line between dots, not only dots themselves
• There no hysteresis (i.e. fans will react on temp change almost immediately)

Potential downsides and risks

• If you quit application incorrectly during manual fan control, fans may keep running on last used speed and will not react on temperature changes
• No idiot-protection. If you set fan speeds to be low, they will be low and your device will heat up quickly

Please test on your own risk (!) and only as a last resort in case you can't achieve desired fan behavior otherwise

GHelper.zip

Updated 13.05.2024

Possible params for config.json (with their default values)

"fan_min": 20, - minimum fan speed (in %) when it's not OFF
"fan_hysteresis": 6, - number of seconds to calculate average CPU / GPU temp (set 1 for instant reaction)
"fan_shift" : 50, - weighted average coefficient between CPU (or GPU) temp and MAX(CPU,GPU) temps in a range from 0 to 100

• If you want GPU (CPU) fan to follow only GPU (CPU) temp, leave it as is
• If you want GPU (CPU) fan to follow MAX(CPU,GPU) temps, set it to 100
• If you want GPU (CPU) fan to follow average between GPU(CPU) and MAX(CPU,GPU) set it to 50, etc :)

If you see a big (more than 500RPM) difference between fan curve and actual readings - try to click Calibrate, it will run a quick measurement process and adjust Y-axis to match actual maximum RPMs

You will see what is actually being set as your fan speeds on Fans+Power screen under fan curves chart. Don't forget to click Apply.

At this setting, the fan speed on the left side of the machine(CPU fan) is at full speed.

At this setting, the fan speed on the right side of the machine(GPU fan) is at full speed.

But, At this setting, fan speed raise to max speed need almost 1 min, not particularly fast.
However, It's worked.

[seerge]

@FliesQQ how fast fans will speed up still depends on hardware of course :) actual command is being sent immediately (i.e. every second)

[FliesQQ]

So this is already very good now.
But FN Lock not work.
And use this should I stop all ASUS services? Now my running Asus service is 0.

[FliesQQ]

If GPU and CPU both in use, seems like CPU fan curve not function correct.

[seerge]

@elxander it is already possible by changing "fan_min": 20, param in config (check main post)

[elxander]

Is it available in release or only in beta builds? I have the latest 0.165, set "fan_min": 5 and see no difference, no red labels with cpu/gpu fans percentage as well

[seerge]

@elxander it is available only in the Experimental build posted in this thread

[elxander]

Thank you. Downloaded it and set to "fan_min" : 1, the lowest possible speed is 1400 now. Better, but over 1800@20 not much really. Is it some kind of limit, or maybe we would need to extend the first step of graph, which is from off to 1800? It seems the profile is set to 01 though i'm not sure because in power user settings there is no description of this line
"fan_profile_cpu_0": "1E-2F-36-3B-3F-42-46-62-00-00-01-05-13-22-2C-38",

[seerge]

@elxander if 1% is 1400 this is how BIOS is programmed on your device

[seerge]

@FliesQQ values that is being set look correct and along the fan curve.

You have mentioned that fans take time to spin up, most probably it’s slightly lagging because of that. Cause, as I understand, temps jump quickly in your testing :)

[FliesQQ]

Yes, the temperature changes too quickly and the fan responds too slowly. If the temperature fluctuates, it is possible that the temperature has risen, but the fan speed setting is still at the low temperature speed.

[seerge]

@FliesQQ fan "setting" is what you see in a red label (so it's practically instant). But how fast actual fans would react on this - is something outside of my control unfortunately

[FliesQQ]

Yes, it's really a pity.

[seerge]

@FliesQQ you can tackle that with a fan curve :) rise it to higher RPMs a bit faster

P.S. I have also updated build in the header-message, now it will refresh speeds once every 500ms (so twice more frequent)

[inthecatsdreams]

Before this update it was impossible for me to set a custom fan curve because of the bios rejecting it, now I can finally set the one I want! Thank you so much!

EDIT: My Laptop is TUF A15 with an RTX 3050

[seerge]

Great news

[fscottcopeland]

Unfortunately this build doesn't appear to be respecting my fan curves still :(

As you can see, the FanCPU and FanGPU percentages don't match what is actually running (confirmed by hwinfo fan reading)

[seerge]

@fscottcopeland can you switch scale to RPM? Asus has quite specific interpretation of % points :)

[fscottcopeland]

Here you go. I've included my HWiNFO graphs too, in case it helps. GPU seems to hit ~71c and then jumps to 5000RPM, despite the 70c point being 4200RPM and 75c being 4600RPM. CPU doesn't seem right either.

[fscottcopeland]

The frustrating thing is that if I disable the custom fan curve, the fans then run slower - e.g. the GPU fan won't then jump to 5000rpm as soon as it hits 70c.

[fscottcopeland]

@Summersoff what's your laptop? Duo 16 2023 too?

[seerge]

@Summersoff then it's just a BIOS idiot-protection, which is actually ... good :) I have similar behavior on my ROG Ally. It would keep fans off until something like 55-60C and then no matter what app sets to it - will ramp them up.

[seerge]

@fscottcopeland if you disable custom fan curve, it's back to whatever default fan behavior is for each of your modes :)

[fscottcopeland]

Yeah. Such a shame. The stock balanced fan curve isn't aggressive enough - whilst the manual fan curve gets overridden and then becomes OTT. I really need a balance in between.

[yesnt10]

Thank you so much! it works great!

[seerge]

@yesnt10 amazing

[manciuszz]

Testing it atm. Seems to work fine so far. Though an optional hysteresis feature would be nice, cause I hear the fans whooshing up and down often

[seerge]

@manciuszz they do :) because one main complains that people accuse G-Helper of - is that fans are "slow" to react and "don't follow curve precisely" (even though when fans are controlled by BIOS it's absolutely not related to the app)

I can add a hysteresis in a form of calculating an average of CPU / GPU temps for last 3 or 5 seconds, instead of acting immediately

[manciuszz]

That would be a nice to have. Preferably, hysteresis could be adjustable by the user, that would allow the user to set their preference whether they want faster reaction times or more stable fan speeds. I personally don't hear the fans because I'm wearing a headset, but I don't think the fans should be whooshing up and down that often either xD

[seerge]

@manciuszz I have updated build in the main post, and added default hystheresis in a form of using average temperature for last 6 seconds. It can be also adjusted via config.

[manciuszz]

Very nice. I'll check it out.

--- EDIT ---
It works really well. I also think the fan shift and hysteresis settings should be available in the UI, so we can do adjustments on the fly, instead of close app/edit config/reopen sequence.

[seerge]

@manciuszz my idea to keep things simple on this stage

[FliesQQ]

I've give up using this function... Now I'm using default setting.

[seerge]

@FliesQQ no worries, default fan curves are best choice for majority :)

Btw I did few more tweaks, and updated release in a header-message here. So you may also check that and see if fans react faster now (or not)

[ElluIFX]

Nice feature, thanks!
It works great on my Zephyrus M15 and acts rapidly.
But sometimes it can't turn off the CPU fan:

Could it be that my method of forcing CPU fan off is not supported？

[ElluIFX]

And it can fully turn off it after I switch to Turbo and back to Silence.

[seerge]

@ElluIFX since it shows 0% in red label, this is what app actually sets as fan speed. As I mentioned in other comment here, it is possible that BIOS would override that as an idiot-protection if CPU is too hot for it's thinking.

[ElluIFX]

@seerge That's really stupid.
What's more, maybe another check box is required for switching the legacy custom mode and this new one.
Anyway, it's a cool feature for me to avoid the broken fan from making noise, thank you.

[Akalikaton]

My Laptop is ROG G14 2020, it's very intersting, after Calibre i cant set the Fan unter 2900 RPM. The Situation is just same like 0.154.0.
I hope the Fan can keep 1000 RPM with 15 TDP, a good Plan for Document read and simple surfing.

[Akalikaton]

PS: 0.154.0 can set minimal 1800RPM and real 1800~2400 RPM

[seerge]

Currently I have set min fan speed to be 25% and max 100% correspondingly (for most laptops 25% would be 1800-2000RPM) Theoretically i can allow even 1% in manual mode, but i'm not sure if it's healthy for the fans ...

[Akalikaton]

Recently i use my G14 almost only PDF and Powerpoint reading, so light, lang battery life and quiet are much important. Maybe i should buy Macbook Air M3...But now G14 works also very well.

[seerge]

I think for office use you can get away with fans being completely off at all. Its also good for battery life

[Akalikaton]

Yeah, and i have heard about, 4800HS performance better than newest 7840H under 10W, a Surprise.

[hadixcanimm]

I bought my laptop in 2019, and Armory Crate didn't allow me to make manual fan adjustments. Since then, I've been researching for a solution every few months. Then I found you and have been using your software, constantly checking for updates, but I still couldn't find a solution for fan adjustments... until today. It's working perfectly now, and your software allows me to make manual fan adjustments. My device is ASUS TUF 506LI. I think the only thing left for me is one setting; being able to undervolt directly on my device without the ThrottleStop application.

[seerge]

I'm glad it works

[Constrat]

Working exactly as expected on G713RW.
Tried the calibration first and I got scared how fast they started ramping up, also with this version I was able to get a much higher calibration max value: (6600 and 6800)
Before I was only able to reach 5400 and 6000, because it was too slow to ramp up.

GHelper keeps on delivering!

[hadixcanimm]

When I completely shut down the fans, I occasionally encounter a blue screen error. On the blue screen, I see an error code like 'fail tdr'. Prior to the blue screen, there are black screens resembling the graphics card attempting to restart itself, followed by the blue screen error.

I don't think it's due to overheating because I monitor the temperatures and they usually hover around 50-60 degrees.

[seerge]

Are you sure it's related ? may be it's just some gpu issues? try to run fans on minimal speeds otherwise :)

[hadixcanimm]

I've set the fans to 1800rpm and never encounter a blue screen, but sometimes, when I turn off the fans, it gives a blue screen error at an uncertain time. To make sure, I formatted the computer and installed Windows 11. I've installed all drivers and will test it.

[seerge]

@hadixcanimm well, apparently something is overheating then :) it may be not CPU or GPU directly, but something on the motherboard itself or so (w/o own temperature sensor). And running fans apparently keep it in a good condition probably :)

[l-naumann]

Thank you! Works a lot better to control the fans on Zephyrus G14 2024 (GA403UI).
However, the fan now runs slightly faster on the slowest setting than with the old build. I use my laptop 95% for office and programming and I can't keep it fanless in balanced mode. Occasionally the fans have to rev up briefly, so I would prefer to run them permanently on very low RPM. At 20% they already produce a very high-pitched noise. Could you add a power-user setting to set the min fan percentage?
I also think that you need an adjustable hysteresis. When the processor is boosted for a short time, there are brief temperature peaks that cause the fans to spin up immediately.

[seerge]

@l-naumann ok. Problem is that different models seem to have different minimum fan speed (and corresponding fan % setting that triggers that) .

At first my idea to mimic asus own fan curves, where 0% = OFF, and 1% = is usually something like 1800RPM (or around 25% of max speed), so people will not have to re-edit their fan curves when they switch.

Reality is more complicated than it is.

Also there is some deviations from actual set value (in %) and real fan speed often. On my G14 2022 20% setting = 25% speed, but from what I have seen here sometimes deviation reaches up to 15% in total ... :|

[l-naumann]

@seerge I see. Maybe the automatic calibration could identify when fans start spinning by increasing fans in 1% steps, starting at 0%. When fans start spinning, add 1-2% as a safety margin and set it as new min percentage.

[seerge]

@l-naumann I have updated build in main post, now it should re-apply fan speeds after wake up no matter what

[l-naumann]

@seerge Thank you, seems to work! Could you please provide a build with min fan percentage = 0% again? Apart from that, this version is perfect for me.

[seerge]

@l-naumann i have updated build in main post again. Now you can set min-fan speed as a parameter in config
"fan_min": 20, - minimum fan speed (in %) when it's not OFF

[RomanYazvinsky]

Hello, @seerge! Is it possible to implement fan control based on highest value of gpu/cpu temperature? I usually work in eco mode and if I set custom fan curve, only cpu fan is running, when by default both fans should work simultaneously. My device - Flow X13 2021

[seerge]

@RomanYazvinsky right, but doesn't just normal "custom" fan curve (i.e. still controlled by BIOS but along your own settings) solve that ?

[RomanYazvinsky]

No, since dGpu is disabled and igpu somehow reports 40-60C under heavy cpu load, gpu fan doesn't even start

[RomanYazvinsky]

@seerge Hello again! Could you please publish a branch with changes in fan control?

[seerge]

@RomanYazvinsky I will a bit later :) it uses absolutely different way to set fan speeds, in comparison to how other hardware commands work.

[seerge]

@RomanYazvinsky I have updated build in the main post and added optional param called "fan_shift" that defines weight of a MAX(CPU, GPU) temp in calculations. So just add "fan_shit":100, to config, and you will get behavior you want :)

[fscottcopeland]

@seerge Is there anything I can give you to see if you can work out why the Duo 16s are overriding manually set fan curves?
Balanced makes my legs to hot lol, and a custom fan curve gets overwritten and annoys everyone around me cos it's too loud!!!

[seerge]

@fscottcopeland i don't think so. Even current approach is already as unorthodox as it could be, as under the hood it just does same as myasus when tests fans (and sets their speed manually).

[UnforeseenHuman]

Hi, I just managed to find this thread to a reddit response. I have been struggling with this issue for about 2 months now, I am using GA503RM and running the current BIOS 318. However I am still facing a fan issue. The CPU fans is the fan which is actually spinning but on G-Helper it shows that the GPU fan is. Even on the custom fan dial, if I change the graph on the GPU fan is when the CPU fans rising up in RPM. The GPU stays put. I managed to used the laptop for a while by gently pushing the GPU fan with a pin without opening the case, this allowed the fan to work but it still did not recognise the fan correctly. I have uninstalled Armoury Crate with the uninstall tool and as well updated the BIOS to 318 but no changes to my problem. It will be great if I can get some help.

The picture below is the current condition of the G-Helper, my CPU fan is running in reality but it shows that my GPU fan is running.

[seerge]

@UnforeseenHuman if pushing your fan physically is the only way to make it spin - it's probably just broken fan.
G-Helper won't solve broken defective fan issue (as I told you on reddit)

You can open Fans+Power an in red label see actual (low level) fan speeds in % that G-Helper sends to your fans. If fans don't spin according to them - there is nothing else I can do here.

[UnforeseenHuman]

It is weird to me as once i physically make it spin, it will continuously spin if even if I shut down and restart the laptop. However once i pull the charging port out then it will not spin by itself automatically again. This is the weird issue I have been facing. I had someone check the fan before and they said it is working but the software is messing things up. I am confused at this point.

Have you gotten someone with this same problem and did physically changing the fan solve the problem? Btw I did not realise that it was you on reddit until now.

[seerge]

@UnforeseenHuman no, so far I had only people coming to github or reddit accusing g-helper that "it doesn't control fans properly" (while in reality it doesn't control them at all, BIOS does that even with custom fan curves and all fan issues are due to the BIOS).

That has led me to digging deeper, and publishing this experimental build that can at least set fan speeds in real time.

[UnforeseenHuman]

what do you think i should do about this, if you have any tips. thank you it will really help me.

[seerge]

@UnforeseenHuman if the fan is not spinning until you physically spin it - i would just replace it in the service.

[NULL0B]

Hi @seerge is this build funtionality present in the newer releases?

[seerge]

@NULL0B no, it's not.

[JV-bug]

Hello,
Middle fan on m16 2023 after calibration shows 7800 max speed, while on 'regular builds' always shows 5600. Mid fan can go that fast?

[seerge]

@JV-bug hello, based on what I have seen Mid fan is indeed often allowed to spin faster than main ones

[Kikimahe]

Hi Serge,

I tested this experimental function on my Tuf F17 and I really regret not having done it sooner ... ;'(

Advantage :

• Ultra-responsive fans
• More precise adjustment of fans curves
• Turbo Boost CPU is maintained much longer (instead of decreasing after 2 seconds)
• Score Cinebench approximately +800 points : the TDP remains at 95-100W instead of 85-90W

In silent mode with défaut curve the fans run at 1800RPM at 40°C.
But I moved the 1st point to 50° (off) and it's OK.

You have done a very good job again. 🥇 👍
Thanks !

[seerge]

@Kikimahe it’s normal. What you see in red labels is actual fan speed in % points that app tries to set at this moment.

What you see on main window - is a fan speed reading, that device reports.

Problem is that fan speed reading is in RPM, and i just calculate % here by dividing current RPM on maximum measured RPM during calibration (or maximum value that app has ever seen for your device). So they may not match super precisely

Also different devices have different minimum possible fan speed (some have like 100RPM others like 2000RPM) which also contributes to this difference

[Kikimahe]

OK I understand better.
Thanks for the explanation. 👍

[Kikimahe]

Hi Serge,

I saw something curious in the config.json file.

I applied CPU limits

• Silent: PL1 50W / PL2 60W
• Balanced: 80W/105W
• Turbo: 95W/120W

But I see that in the config.json file the values are strange different for limit_cpu_x limit_fast_x.

Silent ;

   "limit_total_2": 50,
   "limit_slow_2": 60,
   "limit_cpu_2": 49,
   "limit_fast_2": 80,

Turbo;

   "limit_total_1": 95,
   "limit_slow_1": 120,
   "limit_cpu_1": 80,
   "limit_fast_1": 120,

Is this normal? :)
config.json

[seerge]

@Kikimahe limit_fast is irrelevant and ignored for you. It's FPPT for AMD devices.

[Kikimahe]

OK. I ignore them.
Thanks.

[Anres1981]

Can I have the source code for this experimental version?
I’m assembling it myself, because I need to add a fixation for the normal shutdown of the GPU.
`
return Is("gpu_mode_force_set") || ContainsModel("503");

return Is("gpu_mode_force_set") || ContainsModel("FA506") || ContainsModel("503");
`

[seerge]

@Anres1981 why don't you just set

"gpu_mode_force_set": 1,

In config ?

[Anres1981]

Thanks, it works. Previously this option did not exist.

[Zerotimesst]

umm…… Since I upgraded "ASUSTeK COMPUTER INC. - System - 3.1.27.0", Fan-Control funtion won't run properly. When I click the "Calibrate" button, my laptop's fan won't speed up to the max speed. It's seems ASUS may change something in this driver update.

[Zerotimesst]

I might should to check the config.json file? sry for my broken English. =_=

[Zerotimesst]

Well,when I roll back the driver version to 3.1.25.0 Fan-Control Feature is going to functioning again. It might be some compatibility issues of this newer version of ASUS System Control Interface v3.

[Kikimahe]

Hi,

I installed the experimental version of Ghelper with Asus ControlV3 3.1.27.0.
Calibration works at high RPM values, but not every time.
The RPM values may be very different when you try several times.

Have you tried the calibration several times?
(wait 30 seconds between each calibration).

[seerge]

This build uses same method to set fan speed as MyAsus does when runs it’s fan test.

Check if it works in MyAsus

I’m not at home and have only rog ally with me, but it runs 3.1.27 and everything runs fine

[Zerotimesst]

I have been tried to check it in MyAsus, it seems having some issue in my laptop？ in 3.1.27, MyAsus also can't push my cooling fans to the max speed.

[Githuggerr]

I have a ROG Strix G18 (2024) and set the cpu fan speed to 1% and the RPM is 1800, it's a bit noisy, is it possible to set the fan speed lower, like 1000? Thank you very much for such a great tool.

[Githuggerr]

Where can I find the file config.json? thanks a lot.

[seerge]

@Githuggerr under %APPDATA%\GHelper

[Githuggerr]

Great, when I set: "fan_min": 5, and set cpu fan speed 1600 in the curve, the actual cpu fan speed is 900, which is good for my needs, although I don't quite understand why it's 900.

[seerge]

@Githuggerr there is some minimal speed defined by bios for each model still

[Githuggerr]

Great tool, helped me solve a big problem, thanks a lot!

[ipiegat]

Note: I clicked calibrate as instructed before any testing. Did it a couple times to be sure.

Been using the experimental version... absolutely love the accurate fan control, but there is one slight issue. The image below contains my fan curve. As you can see, both the CPU and GPU fan curve max out at around 3000RPM; however, during a sustained stress test the fans reach and stay at 3800 RPM. I did this on purpose because when set at 3800RPM, the fans actually spin faster into the mid 4000's. To conclude, the fan curve is significantly more accurate, but the fan speeds are off by roughly +800RPM.

[seerge]

@ipiegat hello. It's normal.

As under the hood fan speed is being set in some abstract % points (it's still up to BIOS / hardware how fast to spin the fan), and readings are in RPMs.

Whole purpose of calibration is to measure how much RPM is 100%. But it may still not match precisely on lower speeds.

[ipiegat]

ah okay. i'm not trying to get the "fan_hysteresis" thing to work and i'm a little confused. i'm in "config.json" and i don't see it? am i supposed to add it?

[seerge]

@ipiegat yes, you need to add it (for example to the beginning of the file). What are you trying to achieve?

This feature is so useful to me, I can finally have the GPU (CPU) fan follow the MAX(CPU,GPU) temperatures when applying power limits, just like when not applying power limits.

Glad to hear

@seerge how are you managing to write the fan speed directly? There's something I need to cross-check in the Linux kernel for something similar/related with a few laptops

[seerge]

@flukejones I'm using same command as MyASUS does when run it's fan testing (there it can set fan speed directly) :)

Hi, i have an Asus F15 2021 - FX506HM

My fans seems to be swapped: GPU fan curve control CPU fan, CPU fan curve control GPU. There is something we can do? Some line i can modify or add in the json?

[seerge]

@SalvatoreCrobu hello, can you set one curve to 100% and another one to minimal to actually verify if fans are swapped on your device ? (preferably post a screenshot here)

If it's indeed the case, try this build
GHelper.zip

The fan speed is not correct, for example, I set it to 1800, but it always stays at 2600. Why is this? When the load is low, I hope the speed can be lower

[seerge]

@wrccclight this is how it's set on firmware level for your device. You can try to add

"fan_min": 0,

In config.json, then minimal fan speed that app will try to set will be 0% instead of default 20%. May be real RPM will be lower then.

Hi! Thanks for this package. I'll keep it on hand as a last resort. Would you happen to know which driver is responsible for the GPU fan sensor reading? I'm having a very annoying issue where the system (randomly) stops detecting the speed and displays 0 rpm, but then the fan ramps up to 100% and it's noisy af.
I have a TUF A16.

[seerge]

@jimmygervais-net hello. There is no such thing as a "driver responsible for fan sensor reading". All fan speeds are reported directly from BIOS (via special layer called Asus System Control Interface or even directly).

If it randomly shows 0RPM instead of real one, it's just probably a faulty sensor, not the driver.

[jimmygervais-net]

Thank you for you quick reply. I guess I'll have to send it for a repair then :( At least it's under warranty, but losing my work laptop for weeks just for a sensor, damn! I was hoping it was just a software issue.

[seerge]

@jimmygervais-net you can try to do a hardware reset as explained here https://github.com/seerge/g-helper/wiki/Troubleshooting before doing that, but most probably it won't help :)

[jimmygervais-net]

They specify that they may reset it anyways, and I'll have to make backups, so yeah I might as well do a hardware reset. Thanks for the link!

[seerge]

@jimmygervais-net it doesn't reset any data, just bios settings.
