Well Judith, a lot of dual G5 2.0 seem to suffer from this "problem", including mine. However, what sounds very problematic is not so bad from my experience. Why? Well, I switched from an AMD Athlon system, which produced a lot of noise: The fans were load, I could not really get any soundcard to work without a slight amount of noise, some even started buzzing when the harddisk read audio data etc. All in all, it was a quite-noisy-experience in my studio. Now, the G5 itself is extremely quiet compared to any PC I know. This give, it seem normal to me, that some noise now come through simply because the overall noise floor is extremely low. Sometimes it's bad, because the chirping and high frequencies can more easily get on your nerves than any blowing fan - on the other hand, my studio was never more quiet :) Since non of these noises were in my recordings so far (at least from what I've tested) I don't see any reason why I should give back my dual Mac. And its performance with Logic is simply stunning... Wish you a lot of fun! Cheers, Thomas
