Fan not turning on in silent mode with iGPU

[JohnJohn45]

Sorry for my english

Describe the bug A clear and concise description of what the bug is.

Clear scenario to Reproduce Steps to reproduce the behavior: Start PC with ghelper 126 autostart Use Silent mod + ECO Fan Never turning ON

I use factory default for fan curves (never change it)

Restart PC and bug persist

Use Balanced CPU mod activate CPU fan according to the curves Use standard GPU mod (DGPU) + silent mod activate CPU fan according to the curves

Expected behavior A clear and concise description of what you expected to happen. Fan turning on when CPU temp is > 54°C

@JohnJohn45 hello,

This is probably how Silent mode fan behavior is hardcoded in your BIOS :) I assume Asus wanted to keep device really silent.

• Does it turn on the fans when temperatures get even higher ? like 90C?
• Does custom fan curve (i.e. when you click apply) change the behavior ?

[JohnJohn45]

In silent mod CPU and GPU fan first level is 54°C with fan curve factory default .

1) I use OCCT to stress PC and fans seem to activate only when CPU temperature is more than 80°C IGPU fan not turn on at 54°C but only when CPU fan turn on (GPU was around 60°C)

2) apply curve in ghelper change the behavior and fans seems to work like defined on curves, so it seem factory default curves for silent mod are not good. Maybe i can help you to correct this ?

@JohnJohn45 if after applying a custom fan curve it follows it - then everything is fine :)

As for default fan behaviors, as i have mentioned - this is how asus have programmed them initially. You can't change that.

G-Helper shows whatever BIOS reports as "default", and it's indeed may not always match actual behavior (because asus is asus). Or actual behavior may be more complicated than a simple chart at all (for example, it can wait for a long time for temperature to stay high and only then actually set fans). That's how things are :)

There is nothing to "fix" here, therefore closing this issue.

@JohnJohn45 Hello, if you are interested you can try an experimental build with actual "manual" fan control https://github.com/seerge/g-helper/discussions/2272 . Thanks
