IMPORTANT:
If you can power on the computer, before removing the fan sink, turn on the computer until it warms the fan

separating them easier.
Make sure not to pull the processor out of the socket when you lift the fan sink, especially if you cannot warm
the fan sink prior to removal. Inadvertently removing the processor can damage the pins.
Fan sinks are available for models that use up to a 65 W processor and models that use a 95 W processor.
The fan sink is secured atop the processor with four captive Torx screws.
