2.5.2 Installing CPU fan and heatsink assembly The Intel® Pentium® 4 LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • When you buy a boxed Intel® Pentium® 4 processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, ensure that you use only Intel®‑certified multi‑directional heatsink and fan. • Your Intel® Pentium® 4 LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install. If you purchased a separate CPU heatsink and fan assembly, ensure that the Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly. To install the CPU heatsink and fan: 1. Place the heatsink on top of the installed CPU, making sure that the B four fasteners match the holes on the motherboard. 2. Push down two fasteners at a time in a diagonal sequence to secure the heatsink and fan assembly in place. A B A A B 1 1 B A 3. When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard.
