If the noise is'nt really bad and the console is working fine, you could try to get more use out of it before you drop some $ into repairs because of how it sounds.
By the way, Is your Wii on the stand or laying flat? My Wii was really loud when I had it it on the stand because of the vibration. When I put it on its side, I couldn't hear it anymore.
