Changes

* Using The NASPi Gemini uses the same cooling scheme as the [[NASPi]], we only increased the height of the copper spacer from 6mm to 11mm to allow a heatsink with a maximum thickness of 7mm to be placed on the CPU chip.* NASPi Gemini uses 4010 PWM cooling fan, can support automatic adjustment of speed according to CPU temperature, need to install the shell script.* Support Max 7mm thickness heatsinks installation on Raspberry Pi 4 as we use 11mm height spacers for the fan with bracket installation on Pi4.
