So, here's my situation, where I live the ambient temperature can be a bit high in spring/summer (around 40°C and sometimes more) and I need my rpi to be in an enclosure and to remain cool. Sometimes it's under heavy load as I use it to stream movies or shows via upnp and also to control a 3d printer. I found an enclosure on thingiverse that resembles a computer case that can be seen in the game portal. What's good about this case is that it has space for three 30mm fans and one 40mm fan.
I have read in several places that's a bad idea to plug a fan to the rpi pins (at least directly). How could I power those fans?
I guess I need an extra power supply for them.
Thanks in advance for your help.
Pd: I'm not an expert in electronics but if I have the schematics I can solder components with tin
