Fan Headers
There are eight fan headers on the
serverboard, all of which are 4-pin
fans. Pins 1-3 of the fan headers are
backward compatible with the tradi-
tional 3-pin fans. (Fan speed control
is supported with 4-pin fans only.)
See the table on the right for pin defi -
nitions. The onboard fan speeds are
controlled by Thermal Management
(via Hardware Monitoring) under the
Advanced Section in the BIOS.
NMI Button
The non-maskable interrupt button
header is located on pins 19 and 20
of JF1. See p. 5-4 and the table on
