Headers
Fan Headers
There are seven fan headers on the motherboard. These are 4-pin fan headers; pins 1-3
are backward compatible with traditional 3-pin fans. The onboard fan speeds are controlled
by Thermal Management (via Hardware Monitoring) in the BIOS. When using Thermal
Management setting, please use all 3-pin fans or all 4-pin fans.

TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM), which is available from
a third-party vendor. A TPM is a security device that supports encryption and authentication in
hard drives. It enables the motherboard to deny access if the TPM associated with the hard
drive is not installed in the system. See the table below for pin definitions.
