even if the readings are innacurate 61 is still getting pretty warm. You should probabally look into better cooling. If its stable, how close are you to being unstable? Like 1 more fsb and you crash? IF thats the case then changes in ambient will probabally be enough to bring your system to a halt.
As for temps being screwy - i don't even monitor my temps. Thats why their not posted in my sig, cause even if I did pay attention to them, they wouldn't be accurate. Newbs would get the idea that if the temps they are seeing aren't as good as other peoples, then thats bad.
