Version

OS

Windows 11 21H2

Device

Legion Y9000P IAH7H

Is your feature request related to a problem?

Under the current version, the fan speed adjustment is divided into 10 levels (0~10), which is perfect in most cases, but for some situations that require fine adjustment, such as level 5 corresponds to 2800rpm, but level 6 is 3500rpm, the fan noise is increased by almost 10 decibels, I would prefer to adjust to 3000rpm, but it is not possible in the current version.

How would you like the problem to be solved?

The fan speed adjustment level is more subdivided, such as 0~100

What alternatives have you considered?

LegionFanControl, but direct access to EC, not a good choice.

I'm not really sure since my device doesn't support customizing fan curve, but as I know if you want to change fan speed like that without a ring0 method is impossible. How fan levels & fan speed are corresponded is controlled by EC that's why apps like LegionFanControl access directly to EC I guess, and as bc said somewhere, such function won't be added to llt due to security reason.

Thank you very much for your reply. It seems that this issue has been raised several times, but due to the design of Lenovo, we can't solve it.
