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.
