Right CPU temperature for MacBook?

I downloaded an application today that lets me see how hot my processor is running, it displays the temperature in the menu bar. I thought it was running a little hot, so I did some Google searches and saw the average temperature was about 43-50C, mine's running anywhere from 56-60C.

Is the running temperatures different for MacBooks? In a sense, is this normal temperature for the MacBook? I have good ventilation for it, my fan works fine and all that, but I'm curious as to what average running temperature is, and what's safe, what I should be expecting, etc.

Thank you!
