If your tablet feels like it is getting too hot, the fan may have collected dust. Cleaning the fan should allow it to cool more effectively. On the back side of the tablet, shoot compressed air through the area of small holes to break any dust up. You can also blow in through the USB ports on the top and the docking connector at the back.
Then, use a vacuum to suck any broken up dust out of the areas. Use the vacuum on the slots on the edge of the tablet as well. It is also a good idea to clean out the fan area of your docking station as well in the same manner.
