get a vacumm cleaner nozzle up against all the vents to suck out all the dust and grime you can.make sure you use on a solid surface to keep vents clear.A laptop cooler that plugs into a USB port may also help if all else fails click here
And do not use on carpet or soft furnishing, Smoking makes it worse a lot worse as put stick stuff inside, you cannot then get fluff out as its stuck. That mean disassembly to clean it
