I had several fans from older computer builds, so I hooked up 6 of them together (all red bunched and all black bunched ) to make a bigger fan that i will use as a ventilation system on my shed's attic that i will be building with a friend later this year! I will have 2 sources of power! during the sunny day, it will run with my solar panel that is 12v 2.5a , and i will connect a house light switch in between the fan and the ac adapter to manually flick it on at night time to run it off the power line grid. i was going to throw this away, but why not recycle and use it for efficiency!
