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✬.
So, I'll just need one more quad 2.8, and I'd have an octo!ĭont see where I'd gain performance anywhere doing that though.Kevin, the temps that really matter with CPUs depend on the particular one fitted to your computer, and when you should worry about them depends on the efficiency of control of the cooling system. No hyperthreading for us Harpertown owners but on the bright side, the Harpertown quad core Mac Pro is a dual socket machine with one socket unpopulated. I think Bad Company 2 can use 8 cores, it's just that my Mac Pro only has four, although later this week I'm trying for a stable 3.2GHz from a 2.66GHz Xeon E5430 I have coming and if it works, I'm might stick another in the empty socket for 8 cores total.

Everything I've read says 5400 series won't work in the early Mac Pro, even the 1333 bus ones but I want to make sure. The Xbench score was with drive tests but I've removed the CPU now to try in a 2006 Mac Pro so I can't easily re-run it. Is the game only able to run 4 threads and not 8? You mention stressing all "4 cores" in Bad Company 2. Was that Xbench score with the drive tests enabled? Can you run it again without the drive tests, as it really affects the overall score. It's possible I stuffed that bit up but I can't be bothered re-doing everything when I'm pretty sure the CPU is not going to be up to long term 3.6GHz use. The silver blotches are (badly applied) conductive paint for a voltage boost which made no improvement to stability. The black square is electrical tape on the single contact that needs to be blocked to force 1600Mhz bus. I was however able to play Bad Company 2, one of the few games capable of stressing all 4 cores, at 3.6GHz for 45mins or so before it hard crashed and I was really impressed with how smooth it was, especially considering the 256MB Radeon 2600 graphics.Īlso, seems that you need to use SLANU, SLANT etc type CPUs rather than CPUs with a B in the identifier. The better CPU choice would be a 2.66GHz model which would run at a much less ambitious 3.2GHz, they're also reasonably affordable (Aus$250) right now too and I might try one of these next week. So, the overclock is unstable when pushed, which I was expecting given how high it was.
