I have a MacBook Aluminum (purchased in January of 2009). It's very lightly used, internet basically. Occasional game use. That sort of thing. However, two days a go, I noticed the computer running pretty loud with just searching the internet on FireFox. It wasn't all that hot or anything, just loud and there was this slight grinding sound. I'm guessing that it's the fan failing. I only hear it when I lift the computer to my ear, it sounds like it's coming from underneath the keyboard. I'm hardly tech savvy so I'm not even sure if that's what it is. Other than that, the computer itself is running pretty smoothly. I can't say I've noticed anything different other than that sound. My question is this though, how long can I keep my computer going on like this? I do need my computer for everyday use (I'm a college student, so it's kind of necessary to have one at the moment.) Right now, though, I'm not in the financial area to bring it to the Apple Store to get it fixed (I'm gonna buy AppleCare when I get the money but right now it's just been really tough.) It's gonna be at least a month till I can bring it in. Am I damaging my computer more by using it and not getting it fixed right away?
