Fan throttling for PS3 temperature control

June 3rd, 2011, 01:29 Posted By: wraggster



This setup will let you monitor Play Station 3 temperatures and throttle the cooling fan accordingly. [Killerbug666] based the project around an Arduino board, and the majority of the details about his setup are shared as comments in the sketch that he embedded in his post. He installed four thermistors in his PS3 on the CPU heatsink, the GPU heatsink, the Northbridge or Emotion Engine, and one in front of the air intake grate to measure ambient room temperature.

Above you can see the setup he used to display temperatures for each sensor on a set of 7-segment displays. The project also includes the ability to push this data over a serial connection for use with a computer or a standalone system.

The project is still in a prototyping stage. It works, but he likens the fan throttling to the sound of a car engine constantly revving. Future plans include smoothing out the fan speed corrections and scaling down the size of the hardware used in the system. We’d suggest doing away with three of the displays and adding a button that lets you select which set of sensor data you’d like to display.
