Hot io shield??

Solution
Unless it gets warmer than the air coming out from your CPU heatsink, then it is only the plate/chassis warming up from warm air within. If that really bothers you, then you may want to add extra or stronger intake fans to decrease the temperature difference between the CPU area and room temperature.
