Hey, I have a rMBP (first model, 15", i7, SSD, nVidia 650m) which I used to game on. Recently though, I would start up the game and it would be fine but the performance dropped very rapidly - I can't get a full game of DotA 2 out of it before it runs too choppy to enjoy. Sounds like a heating issue. So I downloaded temperature monitor and SMC fan control. First issue: SMC fan control seems to indicate that my right fan is operating at 0 rpm and I can't get this to change. My temperature monitor seems fine (average 70-80 degrees) but then I looked more in-depth and it seems core 8 is 95 degrees. In addition, it sounds and feels like only the left fan is working. So my question: there ARE 2 fans right? Any recommendations on potential fixes? It's bang in the middle of exam zone, so I can't take my laptop to the shop and lose access to it for a few days. And since other recreational activities after a long day - such as the pub - are out of the question so I do miss playing games. I have got the screws needed to open up my laptop but I don't want to attempt this yet for fear of voiding the warranty. Any help would be greatly appreciated. Thanks.
