the onboard sensors are crap.
On all boards.

The temperatures they display are not reliable and should be taken with a lot 
of salt.

The only important factor is the delta.
And yours is pretty low (1°C).
This shows two things: you are not using cpufreq-scaling, your CPU is running 
on max speed all the time, and there is no need to worry, because your 
heatsink is able to cope with it ;)

Acceptable is everything, that let your box run stable. That totally depends 
on how much the sensors are off the real world.

On my athlon-xp system the CPU started to make errors at 62-65°C. 
The sensors said, that it were 62-65°C - but from a little measurement, I 
knew, that the sensors were roughly 15-30°C off...
