I don't exactly understand your question. So I will try to give more detailed instructions for installing the "Orange Pi Cooling Fan" add-on.
The mentioned add-on cannot work without "Orange Pi Tools" add-on (it's a dependency).
Proceed as follows:
1. Unzip the file "Compiled_addon_virtual.opi-tools-003.zip" This contains two files virtual.opi-tools-10.0.0.003.zip. One is for H3 processors, the other is for H6 processors. Choose the one you need.
2. In Kodi, go to the Add-ons menu - Install from zip file (you may have to allow installation from unknown sources) and select the file "virtual.opi-tools-10.0.0.003.zip". The "Orange Pi Tools" add-on will be installed.
3. Go to the Add-ons - Install from zip file menu again and select the "service.fan.orangepi-0.0.2.zip" file. The "Orange Pi Cooling Fan" add-on will be installed.
4. It's almost done. The "Orange Pi Cooling Fan" add-on must of course be set up. It is simple. Go to the menu Add-ons - My add-ons - Services - Orange Pi Cooling Fan - Configure.
