But if I wanted to power a fan I'd use some USB fan. Example:
Note: I own this one.
I had my Samsung F6400 open today for regular dusting and checking capacitors when I saw a 2-pin header all alone and unused on the power supply board.
The TV is out of warranty so I figure modding the back for a 120 or 140mm fan may help to extend its life a little. Does anyone know if this header can power a fan?
