Over the summer I picked up my rMBP for school in the fall. It has been working great, but probably in the last 2 months, every time I push this computer when gaming (Lego Star Wars, nothing too extreme) the fans obviously start blowing. The computer doesn't get excessively hot, but once the fans start slowing after exiting the game, there is a clicking noise that is very crisp and it happens roughly 2-3 times while the fans are slowing. It isn't the fans making the noise, but something inside that sounds like it is popping. Does anyone else have this problem? Should it be something I should be concerned about? P.S. - My 90 day warranty expired today, fantastic.
