2013 mbpr So I was scrolling through iCloud photos today on safari using my rMBP when I noticed a relatively quiet, albeit noticeable clicking like sound coming from what I believe is the area where the processor is located (near the esc key). I searched online but found no real answer. I did some testing using gfxxardstatus to switch between the integrated and discrete graphics. The noise only occurs when utilizing the intel integrated graphics. When using the discrete gfx card there is no noise. So, my question is, is this normal or not? If no, what steps would you recommend? Does your mbpr make this noise when scrolling a page with heavy media content?
