Mounting the CPU and cooling
Modules
The Pentium II is a module-type CPU which runs at high speeds,
for example 233 ~ 450 MHz, so the cooling mechanism becomes
critifal for system reliability. These are two types of cooling
methods: one with a cooling fan attached to the heat sink of the
Pentium II module, the other with a huge heat sink without any
cooling fan attached.
Both cooling methods for the Pentium II require a "retention
module" to firmly fix the Pentium II CPU to Slot 1. The follow-
ing figures illustrate the steps involved in mounting the retention
module and installing the CPU and cooling modules.
