How to change the data in FNum from 00 to number of my fans.

[RockJesus]

Last, edit FakeSMC.kext/Contents/Info.plist, change the data in FNum from 00 to number of your fans.

I have 2 fans,FNum=ui8 in info.plist,how to change it for 2 fans?

It's base64 encoded, so in your case it needs to be Ag== is 02. See also https://cryptii.com/pipes/base64-to-hex for a better understanding.

<key>FNum</key>
<array>
    <string>ui8</string>
    <data>
    Ag==
    </data>
</array>

(For three fans it should be: Aw==)

Thx!! How do i confirm my fan's Offset value like ur Offset (0xD0)

Use RW-Everything. Open "Access" -> "Embedded Controller" and you will see a table containing values of EC register, from which you can confirm fans' values. Normally they should be close to each other.
For testing, you may use the fn+fkey to enable maximum fan speed, and then press again to disable it, after disabling, fans will stop for a little while before start again. During that process, watch the EC register values and try to find out corresponding offset.

It seems a lot of work to do, I've seen many values are changing under EC reg,It's hard to tell which is the one I need.
