As some of you have seen, I bought my first iMac some time ago, and seeing as it is brand new, I find it distracting, that it is loud. I can hear the fan constantly, the Hard Drive is at 1098rpm-1101rpm all the time. The Optical Drive is at 999rpm, while the CPU fan is at 938rpm. Should I lower them? Will it damage anything? Anything else I can do?
