4. Installing the CPU and Cooling Fan
Pentium II or Pentium III processors can be used on the Thunder 2400. Please
refer to pages 14-18 for the correct CPU jumper settings for your board. Remem-
ber:
•
The CPU is a sensitive electronic component and it can easily be damaged
by static electricity. Do not touch the CPU pins with your fingers.
•
Before the CPU is installed, the motherboard must be placed on a
flat surface. You should be able to insert the CPU with minimal, but
firm, pressure. Do not press down hard on the CPU.
There two types of cooling mechanisms are produced for Pentium II proces-
sors: active (figure 2-6a) and passive (figure 2-6b). 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 Thunderbolt board.

Installing CPU Retention Modules
Installation of a Pentium II / III processor requires a CPU retention module,
which is first secured onto the motherboard. Tyan offers a variety of retention
mechanisms for the different CPU types. See Appendix 1 for options.
