Cooling solution for LCD monitor?



  • @roxx nice! So Im guessing your’s is a pretty big build then. Looking forward to seeing you post it!
    Ya I got several heat sinks that I put on the back of the monitor to ensure the heat gets dissipated.

    Ya, it will be a thick one… mounted Rpi 3 with cpu fan, thats about 12x12x10cms… i will make it such a way that air blows on the Rpi 3 and then same air goes through all the ac/dc adaptors and then to the monitor, finally an exit for it… inbetween i will have heat sinks, aluminium fills/nets to keep the air cool… I have rip opened all the different adaptors from its case and using the circuits from it, changed how the wires will go, etc… i have a “L” shaped wooden structure/design in mind…

    I am doing it this much because i wish to run magic mirror all round the clock with Google assistant…



  • @roxx I do have a question, isn’t it a bit noisy with your fans setup? I have a small fan that came with my RPi case and set it on low so it is silent.

    I also got 10 heat sinks and put them all on the bottom of my monitor back. What used to be too hot to touch for more than a second, now is very cool at all times. I know I didn’t need to put all 10 there, but got carried away and liking the result lol.



  • @dæmoneyesFAN 1 I am using 12v 0.18A CPU Cooling Fan, but i power it with a Laptop charger 1 with 16v 3.5A output so it gives better performance and makes a bit noise, i think we wont hear the noise when its all packed & built in the wooden frame… I had fully opened the fan, cleaned and lubricated it, also works with another Laptop charger 2 with 19v 4.5A output, same noise, superb extra speedy air flow!!! It doesn’t get hot when kept on for 2hours… This is mounted on top side of Rpi3B+, the air will be blown on RPi and then i will direct it to make it flow to the AC/DC adapters…

    FAN 2 Rpi 5v fan, 30x30x30mm… I power it with mobile phone charger 5v 1A… I dont want to power it from Rpi… Tried to power it with 10v 2A but it rotates with ultra high speed, low noise… But it got super hot in just a second… So i m not overpowering this one, also its small… Mounted at bottom side of Rpi…

    FAN 3 12v 0.18A CPU Fan, will be using this as the main air sucker in the wooden frame… Powered with Laptop charger 2
    fan 1 and fan 3 are same model, using both with different power input.

    Finally i will direct all air to monitor…
    During building the wooden frame i may add another small fans to add the air flow for monitor if it gets hot like you had… . The built will be a bulky one in L shaped… It will be divided into 2 wodden box… Will share it when completed…

    And your idea is good for me to use heat sinks as i have a few and got no other use…
    Thanks.



  • @roxx Make sure to post your build in the Show your Mirror page. I’m curious to see how complex and big your build comes out when you’re done. I’ll be posting my own build today or tomorrow.
