and align the guide pin on the bracket with the notch on the triangle side of the processor.
b.
Lower the processor gently and make sure the guide pins on the opposite side of the
bracket fit snugly into notches on the processor.
2.

Clean the processor and heatsink with isopropanol wipes. Allow the isopropanol to
evaporate before continuing.
b.
Use the thermal grease injector to inject 0.6 ml of thermal grease to the five dots on the
processor, 0.12 ml for each dot.
3.
Install the retaining bracket onto the heatsink. Align the alignment triangle on the retaining
