This is a odd question, but are Intel macs louder than previous macs? I just recieved an Intel iMac as a replacement for my dead iMac G5 and both myself and my family has noticed a loud sound (Sounds like a needle playing on an old record player) which is coming from the iMac. My first iMac was very quiet, however when I start using the new iMac this odd sound keeps happening. Is this normal? I am just worried that this scratching sound might by evidence of something breaking down. Also the sound is a lot louder when under Windows XP. Thanks for the help! PS: the sound is loud enough to be picked up on the internal microphone, however I don't know how to link the file to Macrumors.
