Fan Headers*

There are several fan headers on
the P3TDLR that provide cooling
for various components.
tion to one fan header for each
processor, there are two over-
heat and two chassis fan head-
ers. If used, a blower fan should
be connected to the chassis fan
header located near the JF1
header. See the motherboard lay-
out on page 2-9 for locations.
Refer to Table 2-11 for pin defini-
tions.
Note: The maximum current limita-
tion for the onboard fans is 0.6 amps for each,
not to exceed 1.25 amps for any two fans. I.e.
both CPU fans, both chassis fans or both over-
heat fans.
