I purchased a 13.3" MacBook Unibody about 3 months ago, and recently -- about a couple weeks ago -- the fan started to make a noise when it goes about 2000RPM. It'd be a grumbling sound, as if something is stuck, but even after opening it multiple times, I couldn't deduce what it was. So, I contacted a store in a near-by big city which does Apple Warranty and they said I'd have to send the laptop in for a week until they can diagnose the problem, and their last resort would be to actually replace the fan. Since I've replaced a noisy MacBook fan before, and since this is my main computer which I'd have to be without for a week or more, I decided to take the issue on myself and purchased a new fan of the same model from eBay. When the fan arrived, I unscrewed the back plate, etc., but when I got to detatching the old fan, I found the screws were incompatible with my screw driver, and were fixated extremely tightly (never encountered any screws like these before.) So, I purchased a screwdriver set which included the 2 of the most suggested ones on the Internet: the Torx T6 and Phillips #00. Unfortunately, these didn't work either, but ended up worsening the situation as the heads of the screws got scrapped a little after trying and trying. So, now I'm stuck with a new fan in a cleanly sealed bag, a noisy old fan which for some reason has strokes every once in a while and becomes extra noisy -- only "silenced" when I hit the back, and screws which I can't remove to replace the fan. And worse, I've voided my Apple Warranty. Help! Any suggestions? Can I remove the screws with pliers somehow? Drill them? Give it to a computer repair shop?
