I'm just wondering if anyone has used the new 2.5 G5 and if so, does it run any quieter than previous G5's? I had my new 2.0 up and running for only today before I had to take it back (2nd time now.. grr) for repairs. During that time I noticed that it sounded like a windtunnel. I do audio recording so I certainly don't want that extra noise. Is this normal for all G5's or will the liquid cooling make the new G5's quieter?
