Those aren't temperatures I'd want to be dealing with all the time. Max temps are meant as just that. It's a maximum. When you start flirting with them, you're too high.
I'm aware of the max temps...I game, it doesn't even hit 50*C in games...it only goes that high in CPU Benchmarks/Burn-In's...but still i'm gettin a heatsink/more fans so I can do some serious OC'ing safely.
