Ive been reading lately that one of the major problems with the current and recent versions of the MBP is the extreme temperatures that the laptops can reach (around 115-120 F surface temperature at the bottom). In addition to that I've also read this; http://www.webmd.com/infertility-and-reproduction/news/20041208/laptop-computers-may-affect-male-fertility This basically says that a hot laptop on your lap for a period of time can make you infertile, which goes without saying, is no good. My question is I know that peryn will increase the battery time and increase the performance, but will it decrease the temps (CPU, ambeint and surface) becasue of it's smaller size. If so, about how much temp change do we expect to see...? All in all, i love macs, but I don't want to hurt 'the boys'
