Ive had the mini for a day or so and its incredibly quiet and cool. Then I started to wonder should it be THIS quiet? I havent really heard any fan noises at all. If I listen carefully I can hear the clicking of the HDD and a very very quiet whir which may be the HDD or the fan. I put my hand at the rear of the mini and I *think* i MAY be able to feel some gentle cool air but im not entirely sure!
