I have a 2012 base Mac mini that I use for internet and email and in six years of use I have never heard any fan or other noise coming from this computer. I'm now going to purchase a new mini and I want it to be equally silent--everything else is of secondary importance. In configuring my new mini, are there any choices I should make to guarantee a quiet machine. I ask this question primarily in deciding on a 4-core or 6-core processor. The 4-core processor easily meets my needs but I'll pay for the more expensive processor if necessary to insure a quiet machine. Just as an aside, I looked at the specs on Apple for the new mini and it shows the following. So I suspect that all of the mini's will be very quiet: "Typical acoustical performance: Sound pressure level (operator position): 4 dBA at idle" Any recommendations or thoughts would be appreciated.
