I've read through a lot of the threads here about how at least the quad-core 2012 Mac Minis can get noisy under heavy load (e.g. Handbrake transcoding). As far as I can tell, the consensus seems to be that they should be quiet under normal use (web, email, etc.) Is this right? Does anyone know whether, when the fans do spin up under heavier use, the 2.3 GHz machine is quieter than the 2.6 GHz one? I wondered, since it's slower, whether it never gets quite as hot, so the fans don't get so loud? If so, I'd pick the 2.3 GHz as it's quieter, even if it's a bit slower. Alternatively, is it that both models are quiet in normal use, and both are as loud as each other under heavier use, when doing similar tasks? If so, I'd get the 2.6 GHz model, since the 2.3 GHz model would be just as noisy anyway (and I might as well have the extra speed to get the Handbrake transcode or whatever it is done quicker). Can anyone shed light on this, please?
