hello.. recently i found a powermac g5 Quad. i thought it could be a nice computer, well it is to some extend but i found that it's way more noisy than my older g5.. (dual processors 2ghz model) when idle the computer is quiet.. but if i watch flash video in tenfourfox the fans will go up around 2000 rpm.. is it normal for this model ? Also i let the computer on at night when i sleep.. and when i wake up i see that cpu A is around 10 Celsius warmer than B ( CPU A core1=43 CPU A core2=45 CPU B core1=33 CPU B core2=33 ) what i do to get more even temperature is to load a program that use 4 cores at 100% like altivec fractal demo.. then the difference between cpu is more like 6 Celsius... I have opened the computer to see leaks but didnt see anything.. do anyone else experiment these behavior with the quad ? let me know..
