Quieter indeed
I read a german magazine yesteday, called "macnews" thats usually very good and well informed. In this article they explain the cooling device and its features. They offer quit precise information about the noise issue.
The liquid cooling is efficient enough by itself to cool the chips but the liquid that runs back into radiator has to be air cooled. Thats what the fans of the new G5's will do only cool the liquid inside the radiator. To do so the fans only need to spin at a low rate (the surface of the radiator being really huge). The magazine says they only need to spin half as fast as in the rev a G5's.
The thing is if your old G5 was only doing basic stuff, it did not need much cooling and the fans were spinning at a slow rate anyway (quiet). So on a basic job your old G5's and new ones will make the same noise, the fans rotating at the minimal speed. But if your machine is doing some heavy tasking the noise reduction in this new model is about 50% wich is huge.
I guess this machine was made for all you people out there, working as sound engineers. 🙂 And for the rest of us it will make us enjoy the sound of silence.
