Hi, I've had my aluminium iMac 2.4Ghz/20" for about 3 weeks now and I'm *sure* it's gotten a bit louder over the 3 weeks! I can hear it quite clearly at night - not nearly as distracting as my PC, but sat about 2ft away from it, I can definitely hear the fans blowing. I've wondered if it's me getting used to the noise and hearing it far more clearly than I did, but I'm not sure! Is this noise normal? Incidentally, my temperatures (when running MSN, Firefox, EyeTV) are usually about 44-47*c for the CPU and a bit higher (low 50*c's) for the GPU. I know these to be normal, however the fans are always (whether the temperature is high or low) turning at their default speed - 1200/1200/900. Again, is this normal or should they really be throttling down lower? Thanks for listening to the rantings of a possibly paranoid switcher!
