6. Apply some Thermal Interface Material to the exposed area of the CPU that the heatsink will be in contact with, ensuring that it is spread in an even thin layer. Some heatsinks come with pre-applied thermal paste. If so, skip this step. DO NOT eat the Thermal Interface Material. If it gets into your eyes or touches your skin, ensure that you wash it off immediately, and seek professional medical help. To prevent contaminating the paste, DO NOT spread the paste with your finger directly. 7.
1.6.2 Installing the CPU heatsink and fan The Intel® LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • When you buy a boxed Intel® 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® LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.
