CPU coolers usually look pretty similar or at least use a similar technique to remove the heat of the CPU. Almost always you have a block of copper touching the CPU, then a heatsink with lots of tiny thin fins made of aluminum or copper which are heated up by heat coming up from the CPU through the copper base and finally a fan that pulls away the air that has been heated up inside the heatsink. Simple, isn't it?
