J10 and RUN, GLOBAL, GND
I was looking to find out what the J10 header is and what pin controls it. I was also wondering what the run, global and ground holes in the raspberry pi are used for and how you'd access them

J10 port is for fans, you can connect a fan to this port and attach it to Raspberry pi to cooling it.
How could I call the J10 header for variable fan speed? And what's the run global gnd for?
J10 and RUN, GLOBAL, GND
Referencing from the Raspberry Pi CM4 datasheet:
2.13. Global_EN
Pulling this pin low puts the CM4 in the lowest possible power down state. After software shutdown Global_EN needs to be pulled low for > 1ms to restart the power system on the CM4.
TIP: It is recommended to only pull this pin low once the OS has shutdown.
2.14. RUN_PG
This pin, when high, signals that the CM4 has started. Driving this pin low resets the module, this should be done with caution as if files on a filesystem are open they will not be closed.
