NO! Something is broke if it does not work properly. His did not. He was right to demand it be replaced and Apple was right to replace it.
So far the only ones in this thread that were wrong, were the folks that attacked the OP with personal insults.
The only thing "broke" is your logic. If something is broken, it cannot perform its task. If something is defective, it will perform its task but not at 100% perfection. My first iPod touch 2G had a slit between the rubber gasket and glass screen. It's defective, but it still played music, browsed the web, launched apps, etc.
If that's your definition of "broke" (not even grammatically correct), then my house is "broke" too. The floor isn't 100% level and it creaks (aka MBP fan noise) when someone steps on the odd board or two.
Anyway, moving on to stuff that doesn't involve arguing with juveniles. I think if the OP bothered to wait for his MBP to ship, he can wait one week for a replacement. It's not like he lives in some remote area which has zero Apple Stores within a 500 mile radius. Most universities have Apple Stores either on campus or nearby.
Second... I'm curious as to why the OP jumped a mile when one of the first few posts replied "might not get a replacement, probably repair." I think there is some OCD involved.
Second, I recently dropped my MBP about 1-2" above my desk. Afterwards, the HD would spin and make noises. Except, it wasn't the HD. I thought it was initially, but it was actually the SuperDrive. Something got misaligned during the fall. Remembering an old trick, I slipped in a DVD, waited for it to read/spin and ejected it. The noise disappeared. I'm not saying the OP dropped his MBP, but try that trick and see if it works. No reason to get a replacement for something so minor. Replacements are for Macs that have had 3 similar problems (3 HD failures, 3 display problems, etc.) in a major area. Even if something was blocking the fan blades, a new fan would fix it. No need to exchange for a new unit for something so local.
