Yes, this is normal.

You've got to remember that in Sleep mode, most internal hardware such as CPU, Northbridge and other chipsets go into a very low-power state. Because they are still drawing power, they will also still generate heat, and therefore still require cooling.

OK cool, my new MOBO is an MSI 870-G45. I will check to see if it has that. Thanks a lot for the help
