I just got my 2015 rMBP 13" 2.9 GHz, 8gb, 256gb. I noticed that istat read my fan speed at 0rpm. So i ran a stress test to make it start, and sure it did, and istat read the rpm properly. However, once it cooled down again the rpm reading went down to 0 again. Has Apple implemented fan shutdown at idle without telling us? Or is there something strange with my computer? Can anyone with 13" 2015 check it to confirm?
