Does your PS3 cooling system is malfunctioning? Before you go searching for items: Here you get the cooling unit complete with all the trimmings, as shown.
There are two cooling units, even those that were installed in Japan and the United States and who is in European units. The performance of the fan units in Europe is considerably weaker, they have only 15 fan blades (Fanblades). In the non-European devices contain 19 blades, therefore have the same speed at a higher cooling performance. Since the PS3, the speed depending on temperature must be regulated by a fan with 19 blades do not spin as fast to the same power we have to a fan with 15 blades. Accordingly, the fan with 19 blades is better and faster.
