Is it shutting off? There are ways to lower it. The laptop I am currently using is runnig about 47C. You can clean the dust out of the heatsink and fan assembly. You can use a chiller pad that goes underneath the laptop. You can reseat the stock cooler with better thermal paste. You can replace the stock cooler with a better one. There is no tried and true rule of thumb for temperatures 56 is a little high though. Remeber the cooler the better.
Edit: The chiler pad I use is from Antec and its powered buy an Available USB port it lowers the overall system temp buy about 8 deg. It also keeps my legs cooler when using the laptop on my lap
