It is common for Raspberry Pi to get hot, not only because of their use but also because of their design. The latter is the case with the latest model, which heats up very easily. A long time ago we told you how to "cool down" your SBC board. Many of those measurements were homemade and were not adapted to the board, but now one of those measurements is adapted to the Raspberry Pi.
We are talking about the fan. Until now we had to use a computer fan to cool our Raspberry Pi, but now, thanks to Adafruit, we can get a small fan adapted to Raspberry Pi.
This little fan of Adafruit it needs the GPIO port to work. And unlike other fans, remember that we can use any computer fan, this fan adapts to the size of the Raspberry Pi processor so air is not lost and heat can be dissipated without any problem.
Adafruit has created a small fan for Raspberry Pi boards although it is not an official accessory
There is also the possibility of being able to anchor it to the board without any problem thanks to the design of the fan and the Raspberry Pi board. The design is another of the strengths. This mini fan is fully compatible with most official cases and cases, something interesting for those who already have Raspberry Pi with its case.
This component has a reasonable price, $ 3,5. A price that makes our Raspberry Pi board a bit more expensive but that lengthens the useful life of our raspberry boards. In any case, whether or not we opt for this fan, we must bear in mind that if we want our SBC board to not suffer any damage, we have to invest a little money in refrigeration, either in this fan or in heatsinks that reduce the temperature of the board.
