2.3.2 Installling the CPU heatsink and fan The Intel® Pentium® 4 LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • Install the motherboard to the chassis before you install the CPU fan and heatsink assembly. • When you buy a boxed Intel® Pentium® 4 processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, make sure that you use only Intel®-certified multi-directional heatsink and fan. • Your boxed Intel® Pentium® 4 LGA775 processor package should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter. • Your Intel® Pentium® 4 LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install. Follow these steps to install the CPU heatsink and fan. 1. Place the heatsink on top of the installed CPU, making sure that the four pins match the holes on the motherboard.
