I wanted to bring my old 2011 MBA back to life since its still running strong, so I followed this with a new thermal paste, good cleaning and a new battery, its like a brand new computer now. Glad I got the ifixit kit as well when I ordered the battery. Hope to keep this MBS going another year or two before I upgrade. Now I need to do the same with my MBP 2010 for fun.

I have a mid-2011 MacBook Air identical to the model in the instructions, and it frequently gets up to 80C when running under a heavier load. I am planning to disassemble it entirely and repaste the machine, and fully blow out the inside. I will post on here when I get it done and see how it runs! Thanks for the guide!
