In general for XP's you can begin to get unstable as low as the mid to high 50's and the 60's are dangerzone usually.
my general rule of thumb (some cpu's are more tolerant thenn others) is that if your spending much time over mid to high 40's you really need to get better cooling. If you can't run it under load at less then low 50's get betetr cooling. There is a great deal of differance in how the bios reads and reports temps. A bios update can sometimes cause temps to jump 5 to 10 degrees for instance.
AMD used to say 60 degrees in the bios reading the thermister under the socket or 90 degrees on the core itself was projected meltdown. Some of the new chips may change that slightly but its still a good rule of thumb on the XP line.
my main machine with a 2500+ according to the abit utility is 46-47 but thats with folding going to. Also another mahine i have 750 duron is doing 47 c under full load from folding. Also i have a 1900+ at 52-54 while runing folding full force
