Both the finished board and the loose parts come with a heat sink, but the cooling fan is not included. It is recommended that a cooling fan be equipped for daily use.
Several boards power supply interface and component location slightly different, the circuit is the same, the performance is the same. Power interface DC block specifications are 5.5X2.1, inside positive and outside negative, your power interface is the same then can be directly plugged. Your power supply interface is different choose not to install the DC seat of the universal interface, the power line can be soldered directly to the pad, can withstand the greater current.
