I'll put that up when I get home from work. Is the vcore the same as the voltage on the first page of CPU-z.
Intel's thermal spec for the Q9550 is 71.4Â°C. It won't do your chip any harm to run it up to 80Â°C during stress test as the chip will never get that hot except during tests.
For peace-of-mind though, try to keep temps below 70 degrees, which should be easy to do with a good cooler that's up to the task...
