I'm not an expert, but it looks like a power transistor to me. How hot is very hot? 100°C or more is usually within their specification. Some thermal paste could not hurt though.

I have no idea if they are supposed to get that hot on a mainboard, but I guess the heat sink is there for a reason ;). Is the heat sink also very hot?
