4. Installing the CPU and Cooling Fan
Pentium II or Pentium III processors can be used on the Thunder 2500. Please refer to pages
14-17 for the correct CPU jumper settings for your board. Remember:
•
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.
With CPUs reaching much higher clock frequencies, much more effecient cooling methods
must be used to prevent the CPU from overheating. The cooling fan is an important
component that is commonly neglected. Currently, one type of cooling mechanism is
produced for Pentium II / III processors. The active cooler is equipped with a cooling fan
and heatsink, allowing better air flow as well as heat dissipation for the CPU. (See Figure 2-
6 below) The type of cooler used has no effect on performance, as long as the CPU fan is
properly connected to the CPU fan header on the motherboard.
Figure 2-7 below shows an overhead view of the retention braces positioned at both ends of
the CPU slot. Be sure to tighten the retention brace screws to secure them onto the
motherboard. The terminator card must be inserted into the vacant slot if only one CPU
is used.
