Hey all, I am currently using my mbpr to race on IRACING and i am noticing that my MBPRS fans kick on as soon as i enter a race. A race could sometimes last an hour or more and my mbpr is getting really hot. I also notice that the longer i race, the more graphic flickering and shades darkining. Should i be conserned? I am running it through parallels as a vertual machine using a windows 8 demo. Here are my specs..... 2.6GHz Core i7 16GB 1600 MHz DDR3 OSX Also, is there a good app that i can run to check temps? And if there is, what would be a good temp range to keep my macbook within?
