Fan Headers
This motherboard has eight system/CPU fan
headers (Fan 1-Fan 8) on the motherboard.
All these 4-pin fans headers are backward
compatible with the traditional 3-pin fans.
However, fan speed control is available for
4-pin fans only. The fan speeds are con-
trolled by Thermal Management via IPMI
2.0 interface. See the table on the right for
pin denitions.

TPM/Port 80 Header
A Trusted Platform Module/Port 80 header
is located at JTPM1 to provide TPM support
and Port 80 connection. Use this header
to enhance system performance and data
security. See the table on the right for pin
denitions.
Note: The TPM chip can be mount-
ed on the motherboard as an OEM
option to prevent tempering.
