adding fans for airflow?



  • Hi all,

    Today I’ve recieved my Pi 3B+ and right away I’ve installed the MagicMirror software on it!
    And it works!!! Yeah!!!
    So now to set it up…but that’s going to be okay. What I noticed is that the heatsink I’ve put on the Pi’s core is getting “hot/warm”.

    So… my question: would it be usefull to ad a 5v 0.2amp fan in the bottom and top of the frame of the MagicMirror to have an airflow through the frame?

    Yes, or you could place that fan blowing right on the heatsink. That’s what I’ve done. CPU temp is now 30C cooler!

  • @Mykle1 : and did you connect the fan to the wallsocket or to the raspberry pi?
    If it’s to the pi… what pins did you use?
    And how much amp can they handle?
    I’d like to ad 2 fans (1 in the bottom and 1 in the top of the frame) and have them draw power from the raspberry pi.
    I have a 5v 3amp power supply for my pi 3B+.

    The Pi

    If it’s to the pi… what pins did you use?

    One 5v pin and one ground pin

    And how much amp can they handle?

    Dunno

    I’d like to ad 2 fans (1 in the bottom and 1 in the top of the frame) and have them draw power from the raspberry pi.

    Best to check how much draw 2 fans will have. My single fan has no problems

    Okay, Thanks for the answers.
    Will order a few fans from Aliexpress sometime soon. No rush.
    First I want to have the software part ready. 😉
