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

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

I didn't mean the one about this experimental build, I actually asked if there is any documentation about what all the entries in config.json mean and what they do. Thank you anyway. I would also like to point out something like this. With this 0.194 beta version, I was able to control the fan on my 2021 asus tuf gaming f17 model code device, which I normally could not control the fan. However, today I upgraded to 0.195 pre-release version and the fan control was canceled. First I closed ghelper completely, then I deleted the GHelper folder in %AppData%, then I deleted the exe file of GHelper. Then I downloaded the 0.194 stable version and when I tried again, the fan control did not work again. Then I did the same thing again, deleted everything that needed to be deleted, downloaded this beta version and it worked. But here's the thing, I started using the beta version and then the stable version came, I upgraded to the stable version and it was working. I deleted everything and installed the 0.194 stable version and it stopped working, I don't understand why this happened? |

@abdulkadirozyurt Power user settings - is a full list of config settings that you may change (that don't exist in UI) If you are using Experimental build - you need to keep using it , mainstream branch does not have this manual fan control. |

Okay, I get it now, so I shouldn't update until I see this experimental feature in the new stable release description, right? Will this feature come to the stable release in the future? |

@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 :) |
Beta Was this translation helpful? Give feedback.
-
|
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. |

@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 |

Yes, it's really a pity. |

@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) |

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 |

Log extract: 2024-03-23 20:43:21: Mode = 0 : OK As you can see, the FanCPU and FanGPU percentages don't match what is actually running (confirmed by hwinfo fan reading) |

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

|
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. |
Beta Was this translation helpful? Give feedback.
-
|
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. |

@Summersoff what's your laptop? Duo 16 2023 too? |
Beta Was this translation helpful? Give feedback.

|
@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. |
Beta Was this translation helpful? Give feedback.

|
@fscottcopeland if you disable custom fan curve, it's back to whatever default fan behavior is for each of your modes :) |
Beta Was this translation helpful? Give feedback.

|
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. |

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 |
Beta Was this translation helpful? Give feedback.
-
|
@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 |
Beta Was this translation helpful? Give feedback.
-
|
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 |
Beta Was this translation helpful? Give feedback.

@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. |

@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. |

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 ... |

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. |

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. |

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

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. |

@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 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 ... :| |
Beta Was this translation helpful? Give feedback.
-
|
@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. |

If you’re never going to merge the experimental version with main, couldn’t
you have the experimental version update on a separate track? That would
avoid the manual downloads and the confusing auto update behavior but
wouldn’t encourage people who don’t understand the risks/downsides to use
this version.
I’d also buy it as an unlock or something if that was an option offered. I
just want auto updates somehow without losing the benefits of this build.

@RainofTerra hello, Currently I don't want to merge this into main branch. And the main reason is, indeed, I don't want to confuse people and offer them an experimental solution 95% (or 99?) don't even need. I can try to adjust auto-update here, but main problem is that whole update checking process is built around Github API, that shows versions of the latest published release https://api.github.com/repos/seerge/g-helper/releases/latest . But you don't seem to have an option to have 2 different releases. And built in this topic is just uploaded manually ... I may try to create a separate repository just for experimental build tho, unless someone knows a better solution |

Can't the experimental fan component of GHelper just be controlled by an advanced config.json parameter? For the 99% of people who don't use it, nothing would change. For the 1% who do, it could just be a simple addition of "experimental_fan_control" : 1, to enable it. |
Beta Was this translation helpful? Give feedback.
-
|
@fscottcopeland it's a bit more difficult than that :) for experimental build G-Helper uses different driver to set fan speeds. So I will have to include lots of changes into the mainstream release to merge them. Currently manual fan control just replaces default custom fan curve :) |

Is there anyway to achieve the following scenario: When the CPU temp reaches 50C, turn on the fans as usual. Let's say the CPU temp maxes out at 50C. I would like it to cool down to 45C before it stops, rather than 50C. Basically am trying to make the fan stop and start a lot within that 5-10 degrees window. |
Beta Was this translation helpful? Give feedback.
-
|
I think this is a good idea because the processor heats up quickly under load. And, for example, during a game where the load jumps, it might be better to keep the fan at a higher speed in case of unnecessary rpm jumps. But maybe a staggered fan graph or something similar would solve this problem. |
Beta Was this translation helpful? Give feedback.

@seerge OK I set the "fan_hysteresis" to 3, but the fans still start and stop instantly at 50C, same as I set them in the graph. Am I missing something? |

@Eldrasi hello, G-Helper already has quit a lot of automation, but it's more subtle and aimed at non-technical users. It remembers and automatically switches performance Modes when you plug in / unplug, remembers backlight levels, and other small things as well. Next to that it has Optimized GPU mode that turns GPU off on battery, and back on when plugged in. This behavior are also similar to what Armoury Crate does by default. I'm not a big fan of overcomplicating things and introducing some custom scenarios, as 99% of the users won't touch them and they will also conflict with current automations. However if you still want to toggle certain mode in certain event, you can use external autoation apps like Autohotkey and just emit one of existing hotkeys that toggle modes or do other things by yourself as a developer. |

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