Installing the Passive Processor
The installation of the passive processor differs only slightly from that of the
active processor. Your passive CPU package should contain one CPU retention
module, one heat sink retention bracket with mounting locks, two mounting
attachments, and one heat sink lock.Install the retention module as explained in
the active processor section.
The heat sink mount (Figure 17) has two pins on the bottom and four pins on
the top. Notice that the bottom two pins are of different sizes. The size of the
S1846 Tsunami ATX
the retention module. If you have an active processor,
you will also need to connect the CPU's cooling fan cable
to the cooling fan power connector on the board.
Locate the cooling fan connector (e.g. FAN1) on the
motherboard. Plug the CPU's cooling fan cable into the
cooling fan connector on the board. There will be a plas-
tic clip assembly similar to that of the ATX power connec-
tor that will force you to connect the fan cable correctly
(see Figure 16 below).
