Installing the CPU and Heatsink
c) Store the dust cover for future use.
Caution Do not leave an empty CPU socket uncovered. If a CPU socket does not contain a CPU, you must install
a CPU dust cover.
Step 2 Grasp the CPU fixture on the edges labeled PRESS, lift it out of the tray, and place the CPU assembly on an ESD-safe
work surface.
Step 3
Apply new TIM.
Note The heatsink must have new TIM on the heatsink-to-CPU surface to ensure proper cooling and performance.
• If you are installing a new heatsink, it is shipped with a pre-applied pad of TIM. Go to step 4.
• If you are reusing a heatsink, you must remove the old TIM from the heatsink and then apply new TIM to the CPU
surface from the supplied syringe. Continue with step a below.
a) Apply the Bottle #1 cleaning solution that is included with the heatsink cleaning kit (UCSX-HSCK=), as well as the
spare CPU package, to the old TIM on the heatsink and let it soak for a least 15 seconds.
b) Wipe all of the TIM off the heatsink using the soft cloth that is included with the heatsink cleaning kit. Be careful to
avoid scratching the heatsink surface.
c) Completely clean the bottom surface of the heatsink using Bottle #2 to prepare the heatsink for installation.
d) Using the syringe of TIM provided with the new CPU (UCS-CPU-TIM=), apply 1.5 cubic centimeters (1.5 ml) of
thermal interface material to the top of the CPU. Use the pattern shown in the following figure to ensure even coverage.
