Although Zgemma is not expensive but H9 is super fast thanks to arm architecture, I was so amazed especially when I installed Open PLi develop custom build but the RC is not what you expect.
I did some mods and maybe you find them useful too, be aware opening the box means warranty is gone!
Some people say there is no need for a fan but I like things to be cool like myself , didn't want to change anything on the board itself so I used the power input and the fan always is on even when the box is off as it's directly connected to the power source.
I saw a dirty layer on the board and wasn't sure what was that exactly so just cleaned it using a "Electronic Circuit Board Cleaner Spray" first.
When you remove the front glass (which is easy just push it from inside out) you will have better RC but also a bad look
