Thats pretty hot although you don't say how you are measuring the temperatures, is this as reported in the BIOS, or are you using a monitoring program?

What Heatsink/fan are you using? What kind of case cooling do you have?

Is the system stable? If it is then you don't need to worry much about heat, you can tell if it is running too hot because it will be unstable, especially restarting when under a heavy load.
