I've been playing Kerbal Space Program on my new MacBook Pro (15-inch, late 2013 default high-end model with 750M). I've installed smcFanControl to monitor and, if necessary, change the speed of my fans. The default speeds are about 2160 rpm (on the left side) and while gaming it only goes to around 2800 even though the temperatures are ridiculous. I know the computer runs hot when doing tasks, but when I use the High Speed mode on smcFanControl the temperatures immediately drop to okay-hot. I don't understand why the fans don't go over 2800; then again, I get nervous when the computer is so hot it can boil tea and switch on high-speed mode once it gets hot, so it might rise a bit more, but that sort of low fan speeds and ridiculous temperatures is a bit weird. So is this normal? When gaming, what sort of fan speeds do you get on your 15-inch high-end MacBook Pro? Also, another question - I've read people on other forums claiming that higher fan speeds can wear out the fans faster, but if my computer is running extremely hot, wouldn't the temperatures cause more problems in the long term than fan wear-out? Finally, could anyone link me to a free, Mavericks-compatible CPU and GPU temperature monitoring program?
