Installing Slot1 Type CPUs
Currently, two types of cooling mechanisms are produced for Pentium II proces-
sors: active (figure 2-9a) and passive (figure 2-9b). These two types of cooling
methods essentially perform the same function. The active cooler is equipped
with a cooling fan and heat sink, while the passive cooler is simply a larger heat
sink with no fan. The type of cooler used has no effect on performance, and both
types can be installed in the CPU slot on the Trinity 400 board.

*Installing CPU Retention Modules*
Note: Tyan provides a variety of retention modules. For detailed installation
procedures of your module, please refer to Appendix 2 located at the back of
the manual.
Figure 2-10 below shows a side view of a retention brace securing both sides of
the SECC2 CPU. When both sides are properly positioned, press both braces
against the sides of the CPU and carefully lift them over the CPU slot on the
motherboard. When lowering the brace and CPU, be sure to line up the key
notch on the brace with the key pin on the slot located on the motherboard.
