Tyan Computer S1854 manual Installing Slot1 Type CPUs, Installing CPU Retention Modules

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.
