I just picked up a 2.6ghz MacBook Pro 15, brought it home, and set about taking some measurements, mostly for the sake of curiosity. Installed SMCFanControl to check CPU temp and it reads 0%. Strange. Installed iStatNano and no option available to measure CPU temperature. Same with iStat Pro. iStatMenus has CPU Proximity (which isn't the actual CPU diode) and CPU 2, which may or may not be the actual CPU diode. My old favourite Temperature Monitor widget also has no sensor for the CPU, only CPU proximity. So basically my question is simple: can anyone else with a 2012 MacBook Pro, any model, test one or more of these applications (especially SMCFanControl) and see if they have a measurement for CPU temperature. I would really like to know if this is the result of new architecture, or if there is a problem with this particular machine. Thank you very much for any assistance.
