Installing A Heatsink and Fan in 486 and Pentium Based PC

To finish of this section, step-by-step instructions will be given on how to replace a typical Pentium II heatsink and fan assuming the processor has no fan or heatsink installed.  Whether you’re installing the new fan on a 486 or Pentium I CPU, the procedures remain generic for both processors.  This installation assumes you already have the appropriate fan for the processor.  Depending on the type of fan you have, a minimum of four screws and Philips screwdriver is required.

The first step in installing the 486 fan is to open the system case and find where the processor is located.  If any cables are blocking your access to the CPU, simply disconnect any cables and proceed with to step.

Gently position the CPU fan on the processor itself making sure the four corners are aligned with the processor.  If the fan requires you to secure it to the processor, use the four screws and your Phillips screwdriver to securely attach the fan to the processor. If your fan requires you to simply clip it to the processor, make sure it is aligned properly to the processor.

Next find an empty power cable and connect it to the cable attached to the fan.

Power up your system, and your new fan should be working properly.  The overall temperature of your system and processor should decrease.
