• Carefully remove the old thermal paste from the CPU. It is not vital to get the old paste off the parts of the chip under the Kapton tape, but be obsessive about cleaning the silicon chip itself and the area immediately next to it.
• Do not fail to apply new thermal paste to the processor before reinstalling the heatsink. Failure to do so could lead to overheating and the possible death of your processor.
