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. 2-10 Chapter 2: Hardware information
