Hello @prateekp-01 and welcome to AFC community! :wave:

Please, can you tell me a bit more about the temperatures you have chosen? Namely, the increasing step of 1 – why?

[prateekp-01]

That's not the tempratures I had choosen. I used the command sudo asus-fan-control set-temps 60 65 68 70 72 75 78 80

So you set temperatures and get different temperatures, right? If so, I am in doubt that AFC works on your laptop. Do set temperatures really affect your fan speed? For more info, see our AFC wiki troubleshooting.

I tried running the command sudo afc-scout ------ base address 1335 ------ [1334] = 54 [1335] = 55 <- possible start [1336] = 56 [1337] = 57 [1338] = 58 [1339] = 59 [1340] = 60 [1341] = 61 [1342] = 62 <- possible end [1343] = 63 ------ base address 1431 ------ [1430] = 150 [1431] = 151 <- possible start [1432] = 152 [1433] = 153 [1434] = 154 [1435] = 155 [1436] = 156 [1437] = 157 [1438] = 158 <- possible end [1439] = 159

Also I tried using two very different temprature ranges but felt no change in fan speed.

I'm really hoping that you will help me. I recently started using Ubuntu replacing Windows but I'm facing a big problem that cpu and gpu fans are constantly running at quite high speed and that's draining a lot of battery and also is too annoying. If this problem will not be solved I will have to switch back to Windows which I really don't want to. I tried almost every solution present on AskUbuntu and so you are my last hope :)

Unfortunately, I must tell you that this looks like one of the notorious issues with some models (see some issues with the set but not get label), so I would not expect that asus-fan-control itself would be of any help here. :cry:

Nevertheless, have you tried https://github.com/hirschmann/nbfc and https://github.com/daringer/asus-fan? Neither should have support for your particular device but it worth the try. BTW do you know about https://wiki.archlinux.org/index.php/fan_speed_control? It may be helpful as well.

Anyway, should you find something that helps you, please let us know! :rocket: The ASUS community will appreciate it.

Thanks @dominiksalvet . I haven't gone through those but will check them soon.

Hey there, I have the same laptop and experimented a bit: My experience is that the return value only depends on the first byte we give to read_acpi_value() (beautiful plot in #5). Consequently, read_acpi_value(55) == read_acpi_value(1335) and read_acpi_value(151) == read_acpi_value(1431). I don't know if this holds in general or only for the set-but-not-get devices.

However, if you call read_acpi_value(132), the laptop fan stops briefly. Going a bit further, if you write to this address, it seems one can set the fan duty cyle -- but only for <1s, until the fan is put back to the default. Maybe there is another register where the fan can be switched from automatic to manual mode to actually make this useful? 😅

@kenohassler Good findings! Should your investigation continue, let us know about the progress. :rocket:
