No AMD 64 processor has a maximum temperature less than 65C except for the FX-57 at 63C. Most have a higher max. The FX-55 is about 70C like I said earlier. Whoever told you 60C for ANY AMD 64 processor doesn't know what he's talking about.
Now it's true that temperatures above 60C for most 64s will start to decrease the CPU life, but it won't burn out.
Here's some more reference:
