4.2 Headers and Connectors
Fan Headers
There are eight 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)/Port 80, which is
available from a third-party vendor. A TPM/Port 80 connector is a security device that supports
encryption and authentication in hard drives. It allows 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.
GPU Power Connectors
Four power connectors for GPU and VGA devices are located at JGPW1, JGPW2, JGPW3
and JGPW4. Connect an appropriate cable to each GPU power connector to provide power
for your GPU/VGA devices.
