In my experience, laptops generally run hot. However, I have cleaned dozens of laptops and one thing that I see common in all of them is that dust, lint, hair, and whatever else builds up between the fan and the heatsink. If your laptop is running a bit hotter than normal, I would definitely consider this as a probable culprit. Unfortunately, the build up is not easily removed without disassembling the laptop to a point where you can remove the fan and get at the buildup directly.
Once the buildup is removed it can be prevented by shooting some canned air into the exhaust vent about once a month or so depending on your typical computing environment.
