Fan Headers
The X6DHR-C8 has eight fan head-
ers. (*Note: These fan headers can
support both 3-pin fans and 4-pin
fans. Pins #1-#3 of 4-pin fan headers
are backward compatible with the
traditional 3-pin fans.) The fan speeds
are controlled by Thermal Manage-
ment via BIOS under the Hardware
Monitoring section in the Advanced
Setting. See the table on the right for
pin defi nitions.
Power LED/Speaker
On the JDI header, pins 1-3 are for
a power LED and pins 4-7 are for the
speaker. See the table on the right
for speaker pin definitions.
The speaker connector pins are for
use with an external speaker. If you
wish to use the onboard speaker, you
should close pins 6-7 with a jumper.
