Fan

The phyCORE-AM57x Carrier Board provides fan connectivity via a 2-pin Hirose connector at X36. The fan is intended to be mounted directly to the processor heat sink for thermal management. The 5V power supplied to the X36 connector is regulated from the VDD_12V0 power rail through an LP3878-ADJ regulator at U12. The regulated 5V output is enabled by driving X_GPIO7_5 high. When X_GPIO7_5 is pulled low, the 5V supplied to the fan connector will be turned off. The default behavior of the phyCORE-AM57x is to have this fan turned on. To learn more information about the phyCORE-AM57x fan utilization, please see section 30 in the Hardware Manual.
