Hi
On lenovo miix 720 the problem is the same of lenovo 710.
Config file of 710 miix help only to detect temp value but do not help to adjust anything.
Please add a config file for lenovo Miix 720

I have the same issue. A config file for the "Miix 720" would be great.
@Sursodd commented on GitHub (May 12, 2017):
Hi,
I've tested some of the configs and the one for the "Lenovo Yoga 3 14" affects my fan. Maybe this config can be modified for the Miix 720.

Hi, I need that too. I have tried using rw everything to find out the write register, but it seems that 3 register is related with the fan, and I don't which one should be the write register.
@duguyushu commented on GitHub (May 20, 2017):
I have use one register and successfully control the fan speed. However, it seems that the notebook fancontrol service conflicts with system ACPI, and the ACPI service tries to access EC, mostly fails, and sometimes success. Even though I set EC pull interval to minimum 100ms, the fan will be sudden start and stop for a very short time, looks like it is suddenly started by ACPI and quickly stopped by fan control. Does this problem appear on other notebooks? Is there any solutions?

Maybe I got the same problem with you on Asus K501UB. If the CPU temp is higher than 40oC It keeps spin 4000rpm or higher even I don't use any weight application. I don't know how to set It to 2000 or 3000. This sound drives me crazy.
@int3ks commented on GitHub (Sep 11, 2017):
same problem here. does anyone know what tries to restart the fan ? is this the bios the EC controller itself or an acpi device on windows??? anyway to stop this? it sounds like a defectif harddisk! i dont like this sound :(
@chrismin13 commented on GitHub (Apr 12, 2018):
Any updates on this? I'm considering getting a Miix 720 to replace my Surface Pro 4 since I'm afraid it'll start flickering. Is the fan really that annoying? Does NBFC work, or is the clicking sound still there? Thanks.
@soohwan-hyun commented on GitHub (Jan 23, 2019):
I solved this problem in a slightly different way.
control panel -> power options -> edit plan settings -> change advanced power settings -> processor power management -> maximum processor state change( < 90, my case ).
It seems that the fan is operating at the maximum speed in the process state of 95 ~ 100.
So I just modified this part, but I've reduced a fan noise except for the heavy duty work.
It will not be a fundamental solution, but it will help miix720 user like me.
