Hurrah, just used these instructions to replace my fan and have a beautifully silent working laptop again - thanks! I skipped steps 20-23, and it would have been useful to have a mention that thermal compound was necessary to make a good connection when replacing the heat sink - but all in all great clear instructions. One happy good-as-new laptop owner!

This guide was bloody marvellous! This was the first time I’ve opened a laptop by myself and it was quite a ride but a fun one the only struggle that I had was the bloody blue ribbon connecting to the motherboard other than that the rest was really easy to follow. Thank you so much for the guide and I hope I can some day be a contributor just as great as you random internet person ^^
