So I heard this awful noise coming from my right speaker when I was installing photoshop, and I assumed it was my fan. I did some google searches and listened to some video clips of people with similar problems and the noise seems to be the same, indicating that I have a problem with my right fan. The noise has been happening since I moved my laptop home from college a few days ago, but it goes noticeably worse tonight. However, my left fan doesn't seem to be working at all. I used iStat (widget) and Fan Control to verify that my left fan is spinning at 0 rpm. Annoying fan noises have been going on for a long time, maybe since I got my computer three years ago... But I shrugged them off like an idiot. Anyway, I seem to remember my left fan making lots of noise when I was having this problem a year back or so. Now it seems that the left fan in completely dead, and the right fan is overcompensating and starting to break down now too. Two questions: Can I be sure the left fan is broken, or does the left fan only kick on sometimes and I just haven't witnessed it tonight? Should I try to fix it? I'm not under warranty and the parts are about $60. I'd prefer not to spend a million dollars on labor; my dad and I are pretty smart and can probably fix it ourselves. Please add any other advise you can muster! Thanks so much!
