So while the fan might be running at the same RPM air flow is lower and heat increases, so the system senses the high temperature and tells the fan to run at a higher speed. Same thing that happens with fat clogged arteries. The solution is simple: buy yourself an AIR COMPRESSOR. Use it once or twice a month. Do it with the system running and plugged to AC. Just blow compressed air into the air intake vents at the back of your laptop-notebook. The air you blow in will free the dust, and the system´s normal air flow will expell a dust cloud out of your computer. It´s inmediate. Just a 4-5 sec blow of compressed air (move the air compresor from side to side to cover all the air intake-exhaust vents) will do. It´s amazing the amount of dust that gests out of my system (a 5 years old AMD Athlon 64) on each monthly cleaning exercise. My father owns a P4 Sony VAIO and he complained all the time about his system overheating. I told him about the air compressor trick and now his problem is gone. Desktops need such cleaning as well, although not as often (the space in the cooler-heatsing is larger and as such it takes more time to get clogged with dust).
