Fan Headers
There are three 4-pin fan headers (FAN–FAN2, FANA) on the motherboard. All these 4-pin
fan headers are backwards compatible with the traditional 3-pin fans. However, fan speed
control is available for 4-pin fans only by Thermal Management via the Hardware Monitoring
in the BIOS. Refer to the table below for pin definitions.
General Purpose I/O Header
The JGP1 (General Purpose Input/Output) header is a general purpose I/O expander on a
pin header via the SMBus. Each pin can be configured to be an input pin or output pin in
2.54mm pitch. The GPIO is controlled via the PCA9554APW 8-bit GPIO expansion from PCH
SMBus. The base address is 0x5000. The expander slave address is 0x70 for WRITE and
0x71 for READ. See the table below for pin definitions.
Intel RAID Key Header
The JRK1 header allows you to enable RAID functions for NVMe connections. Refer to the
table below for pin definitions.
