My fans were starting to sound like chainsaws. Since I was opening the computer anyway, I decided to upgrade the RAM for Mavericks.
I decided I'd give DIY repair a shot because my macbook is out of warrantee and I don't feel like paying a new computer price to deal with a minor problem or overpaying an Apple store to hold my macbook for 2 weeks to do less than 30 minutes of work. The repair didn't take long at all. I needed 1-2 minutes to get the bottom of the case off to get to the insides. The RAM took no time at all. The fans took 5 minutes or less a piece. Now that I could see for myself, I could tell the fans were shaking as they rotated and scraping against their casing.
I never had the tools to open the macbook myself before, and in doing so found out the reason the bottom casing wasn't sealed tight anymore and the reason the touchpad barely worked anymore was because the battery was bulging. I'm glad I finally did something myself because AppleCare had seen the computer twice, and when I asked about those two issues, they tried to tell me the casing was too bent and I'd need to pay $250 to replace it. They never mentioned the battery either time. Either they failed to notice it or did not want to tell me because Apple warrantees don't cover batteries. I ordered a replacement battery and hope to have this computer running slightly better than new soon.
Have the tools to look at the inside of your computer yourself. I never would have known my case wasn't closing properly and my trackpad was not working because of an expanding battery if I had not looked for myself. AppleCare neglected what I would view as a major issue.
If I had the tools to open up my macbook before I ordered parts, I'd also have the battery I need already. Luckily ifixit ships quickly.
