Funny how there's one thread worried about the mini being too quiet, and another worried about it being too loud!
In the absence of any considered evidence of a design or production flaw, I'm generally of the opinion that Apple engineers, with degrees and experience in the relevant area, thought about such things for a fair amount of time, and there's no need for me to spend my time using utilities to monitor CPU temp, fan speed, memory usage, network requests, process launching, etc, etc -- when there's a perfectly good operating system to do that for me.
OF course, there's still the possibility of a Mac that went through the factory at "end-of-shift", which might have a unique problem. But, unless there is a noticeable, observable problem, (most of which are likely to manifest immediately or within the warrantee period), I'm inclined to advise: "Leave it, it'll probably be fine."
