I am not confident that i) I'm going about monitoring my temps in OS X properly, and ii) that monitoring temps in OS X is accurate even if it is done properly. Q 1: Am I monitoring properly in OS X? I installed, using Multibeast 3.1, fakeSMC and fakeSMC plugins. I also installed iStat Menus (3.01, I think). I see 4 cores, with 4 individual temps, and VCore. VCore matches what I get, roughly at various steppings when I compare to CPU-z in Win7, so I'm confident with that. In Win7 I measure temps with Real Temp, which shows distance from thermal max (so even if the absolute temps aren't right, I can get a sense of how close I am to hitting what Intel thinks are the highest temps before throttling the processor). Unfortunately, I don't have a way to compare, say, prime 95 load in Win7 to something similar in OS X-- I've found Prime 95 for OS X v. 25.11, but it seems old, and I don't know if I can use that to compare load temps to prime 95 in win7? Q 2: If I'm doing everything right-- fakeSMC + plugins from multibeast 3.1, followed by iStat Menu-- what are the opinions regarding the accuracy of the readings I'd get from iStat Menu? Part of the reason I ask this, is that I've hit 90 c in intel burn test before stopping, at some overclocked settings, and gotten BSODs, whereas with the same settings in OS X, runninge cinebench CPU benching or handbrake running at 90% total load, I don't go over 75 c in OS X and don't have stability issues in OS X so far.
