well if this has developed over time i would dust the whole computer... take off the heat sink and clean out between all the blades on it... clean the fan really well all that stuff...
but theres always upgrading the heatsink... dont know what hardware your running so its hard to recomend one...
and theres watercooling if you wanna go that route...
