Onboard Fan Header
This motherboard has ten fan headers (FAN1~FAN10) used for CPU/system cooling. These
are all 4-pin fan headers, which are backward compatible with a traditional 3-pin fan. The
onboard fan speed is controlled by Thermal Management (via Hardware Monitoring) in the
BIOS. Please use all 4-pin fans on the motherboard for better thermal management and
system cooling.

TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM)/Port 80, which is
available from a third-party vendor. TPM/Port 80 is a security device which 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 layout drawing below
for the location of JTPM1.
RAID Key Header
A RAID Key header is located at JRK1 on the motherboard. The RAID key is used to support
onboard SATA connections.
Standby Power
The Standby Power header is located at JSTBY1 on the motherboard. You must have a card
with a Standby Power connector and a cable to use this feature. Refer to the table below
