yea that looks fine, anything that is 60-70 or below (while gaming) or 50 or less when idle is fine, im sat at all between 30-40 when idle, 35-47 when gaming, so it is fine.
All hardware fails (cuts out power so shuts down) at 100, unless you chancge the settings to prevent damage and all hardware, including cables and stuff, fail at 105 degrees, or so says the writing on them. That means it is actually a little higher, they say 105 just to be safe from any kind of law case being put against em if they say 115 and it fails at 110
