@dæmoneyes …FAN 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.
