Michael Dornisch’s DIY Raspberry Pi Heat Sink.

As seen above, the infrared thermometer shows a temperature of 38.8 degrees Celcius. That’s a difference of 17.3 degrees from the average temperature during network video playback! That much improvement will go a long way towards overall system efficiency and stability. Further implementation can be done with a 5v low profile brushless fan that came from a dead netbook. The fan could be powered directly from the GPIO pins. If it is possible to read core temperature with the SoC, then it could even be possible to utilize the GPIO with the fan in order to have the fan be intelligently controlled based on the SoC temperature, all with a simple python script.
