Learning with Raspberry PI, Delivery VII - excessive temperature and different forms of cooling

In the previous installment of Learning with Raspberry PI We saw as monitor our Raspberry with RPi Monitor, and many of you may have noticed that according to the use that we are giving you, especially if we have done Overclock and/or Overvolt, the temperature of our Pi has increased.

Idle

Raspberry newly lit and no Overclock.

Investigating areas of the Raspberry are heated more, I have come with a complete study published in Geektopia, and I've cooled it accordingly in two different ways that perfectly complement, Since the Pi can be quite warm.

Raspberry giving everything without overclocking.

To lower the high temperatures, avoid crashes, or that the life of our little be too shortened due to heat, You can refrigerate it sticking ones heat sinks in parts of the Raspberry that more heat emitted.

Heat sinksIf this is not enough, We can connect a 5V fan to the pins GPIO as in the following diagram to cool in a way more efficient our Raspberry.

Connect fan.With sink We went down between 2 and 3 degrees Celsius, and by adding the fan We may lose a total of 25 degrees Celsius, as we can see in the following test before and after with the Raspberry lit during 14 consecutive hours.

Try ventilation.For an option more silent, We can get our own system of cooling liquid for Raspberry, There are different designs tested but I have not implemented any of them so I can not offer temperatures data, just to show you this third possibility.

Water cooled

    • In a box so small, the ideal is to focus a flow of incoming air to sinks, or particular point you want to refrigerate, in this case the ARM and the USB/Ethernet chip.

      Being the small box with holes, the air will seek to get out of it, passing first through the inside and taking hot air that those parts of the Pi.

  1. Because connect the fan to the pins 2 and 6 and connect it to pin 4 and 6 taking into account that the 4 has the same function as the 2 (5v power PIN).
