Fan Headers
There are three 4-pin fan headers on the motherboard. Although these are 4-pin fan headers,
pins 1-3 are backward-compatible with traditional 3-pin fans. The onboard fan speeds are
controlled by the Thermal Management (via Hardware Monitoring) in the BIOS. When using
the Thermal Management setting, please use all 3-pin fans or all 4-pin fans.
General Purpose I/O Header
The JGP1 and JGP2 (General Purpose Input/Output) headers are general purpose I/O
expanders on a pin header via the SMBus. Refer to the tables below for pin definitions.
