For monitoring there is Coretemp http://www.alcpu.com/CoreTemp/
is popular then there are realtemp, speedfan and others.
50°C is high unless your ambient is in the 40's! Make sure your Cooler is properly seated with the push pins firmly inserted.
Thanks for the info. By ambient temp are you talking about room temp, or case temp?
M room temp is around 22C. It's not crazy hot in here or anything. I'll give the cooler a once over and see if that helps.
