Hi guys, i was testing my setup when and after 5 minutes i noticed my fan would lose lots of speed, and an led light connected to the same terminal block would dim drastically. After e-mailing Dave he quickly notified me that the problem was cause by the U6 voltage regulator overheating. I added an aluminum heat sink with compound, and disconected my led light. However, U6 still heats up. Is this normal and will it affect the performance of the board, everything else seems to be working fine. Any help greatly appreciated.
