Thanks for the guide. I was able to successfully replace my fan using it. I would like to point out a couple of things:

1. 10 minutes is not a realistic completion time for this guide.

2. Disconnecting the fan plug is challenging. It might have been easier with a small pair of pliers.

3. Since this guide involves dis/re-connecting the thermal interface between the processor and heat sink, you should be prepared to properly clean both surfaces and re-apply new thermal compound. There is an excellent guide on applying thermal compound here:
