Safe temp under load/ under voltage

I just built my first computer and i am using an fx 4170. I have read that the max temp for it is 61c but what is a safe temp under load? I have heard that it is good to run prime95 to test for temps and I haven't done that but after I ran 3d mark11 benchmarks only it was at 55c and on idle I'm at 30c is this hot?...

the Phenom IIs were pretty easy to OC with an undervolt on a lot of those chips, if u had one it was amazing the speed, and how easy to keep cool

@ OP,, ur temps r fine, if u want, do like sparker said and pick up an EVO when they go on sale

And no you don't ever want to undervolt ever. The temp benefits it may give you are miniscule and won't matter one bit.

AMD usually "undervolts" their own cores within a 100~200mV range to achieve a full TDP spread.  I can't speak for FX CPUs, but I know I've seen Phenom IIs exhibit better than d(V^2) scaling with undervolting at high clock speeds, which is no joke.

The listed maximum temp is usually where the CPU can operate safely for like 3~5 years.  Life expectancy roughly halving or doubling with every 10C variation.  Though I think a lot of times with AMD the listed max is actually a thermal runaway point.  You could run anywhere under 100C for limited periods without breaking anything.

So the 61c amd puts on the website is kinda like expiration dates, they can usually go past but they put it there so they don't in trouble from someone frying their CPU at 65c ?

You are worrying about nothing. Your temps are fine on a stock heatsink. Your load temp can go a good bit higher then the 61c you supposedly found. You can probably run at 70c under load an not do any harm what so ever to that cpu.

If you are concerned about temp change out the heatsink to a coolermaster hyper 212+ evo and don't worry.

And no you don't ever want to undervolt ever. The temp benefits it may give you are miniscule and won't matter one bit.
