But that is ancient history, even in the Windows world.
In those days, when macs were running PPC or G series processors, temps in the 60's for some Windows machines with Intel Pentiums were getting close to the maximum they could cope with. Your friends speaking about such things might be remembering the far, far lower temps that older Wintel Pentiums could cope with. At this point the thing is barely getting into stride. By this temp OSX should be kicking the fans in enough for you to notice (If you are running under Windows and Bootcamp it may even be somewhat higher, so I guess MIcrosoft have greater faith in Intel's own figures than Apple! ? )īut 60º to 65✬ is nothing for a modern C2D CPU temp. I'd worry, too, if you aren't seeing some increased fan activity by about the 75✬ mark. If I accept the word of the CPU manufacturers, at a minimum of about 15ºc above that. When should you worry? Conservatively I'd say if your CPU is running constantly above 80✬. It is pretty hard to imagine that they don't know what they are talking about, given that they actually manufacture the processors, and the catastrophic costs of replacement which could ensue if they got it wrong, don't you think? Now, being a bit conservative about such things I wouldn't be happy either if my CPU was hitting the 95✬ to 105✬ range regularly, but the manufacturers of these CPUs, Intel, reckon this is the area where we should start to get worried, and have therefore introduced their own "throttles" on CPU speed, and ultimately cut offs to prevent damage, at around those points.
The fans tend to kick in somewhere in between these temps, and the maximum temperature they are capable of handling before the CPU itself does just what the "Coolbook" software claims to do (throttling back the CPU speed etc) varies between about 95✬ and 105✬. MBPs regularly operate in that 60º to 70º C range that you mention if they are under a bit of stress. But their fans cut in earlier and, as long as they were working properly, CPU temps were very rarely any sort of real issue with them. IMac G5s, for example, had CPUs that would get to 65✬ far faster than an Intel MBP does, and had a maximum rated temp of only about 85✬.
