I started getting the same problem about a week ago, but on the upper right hand fan aparently. It's so annoying. im just about to move house aswell, argh stress!!
Does anyone know if having the beta vista installed with the efi partition deleted voids any kind of warranty, so i know whether to just get rid of it all before i take it in for a service?
Also if it does need to be serviced, will this cost me? I didnt get apple care and i got the macbook around a month after they released them.
Siigh. I thought the problems were over, id decided the whine with battery, and heat were liveable with, but this is just stupid.
