Hi, my brand new Retina MacBook Pro emits noise in two situations: 1. When using the SSD a high pitched noise is produced, it is located where the SSD is. The noise is reproducable with BlackMagic Disk Speed Test. This occurs with 4 out of 4 rMBP I have tested. 2. When doing anything which involves graphic, another noise is generated. Reproducable by simply scrolling a webpage. Is this normal behaviour?
