DIY: Avoid overheating problems on your PS3 with a chip and sensor for 5 bucks


With a small chip Digispark ATtiny85 will see how to regulate the fan of the PS3 (or any PWM-controlled fan) depending on temperature, avoiding wear and tear prematurely. 
Engineers PS3 gave priority to the silence of the PS3 , since it is intended to be a center of games and multimedia, so the processors can reach damaging temperatures for the welds thereof, and within a few years ends up breaking down by poor contact welding (reparable only with reflow or reballing).
The PS3 has a pulse PWM controlled fan, Atmel ATtiny85 and can be easily programmed with the Arduino IDE.
There are examples on Youtube and internet people that has regulated the fan fixedlyto go ever faster (with a resistance in the gray wire connected to the 12V, regulating 1V approx., Or with a potentiometer to do it manually) but is not the best solution because it does not consider the processor temperature (which can vary greatly depending on ambient temperature), and although it works, having to cover all cases, there isusually noisier.  and with this solution we have the advantage that if we hear the very loud fan, you will surely have a problem of lack of ventilation dust or other problem.
