Help how? I have already told you that your temps aren't too hot. You can't compare two systems, even with the same parts, and expect exact results. There are too many variables.
The case airflow in yours might be worse than your friends case. Your heatsink might have a rougher surface. You might have too much/too little thermal paste. Your CPU might produce more heat than his. Your voltages may be higher than his. Your room may be hotter than his.
50C on load isn't bad. Your friend might be using Cool'n'Quiet, and you might not be. That would produce those lower temperatures.
