   So I bought a case called 'Unity V2' and it's supposed to be for a RPi4.   
   There's assembly instructions on their site showing the fan should have   
   3 cables (red, black and blue), but the fan has a fourth (green) cable?   
      
      
      
   The sticker on the fan says 'Pi-Fan model: ODS-232-3007' which should   
   have 3 cables.   
      
   My question: can I still use this fan for my RPi4? Cut the green wire or   
   simply not use it?   
      
   This is what I have:   
      
      
   (I contacted the shop, but they haven't replied yet. Guess they are busy   
   with Black Friday and all that.)
