I'm using good pc fans, Panaflo and the magnetic bearing types. I am just running them outside an enclosure with grilles to cool the motors.
I have a kingwin hard drive kit to run internal hard drives via USB which has a molex ac adapter. For reasons unknown to me, it'll run a hdd but won't power up one of the 120mm fans I have.
I'm not handy with wiring if it requires soldering and knowledge of components and such. I was just confused as to why the ac adapter for the hdd kit didn't power up a fan and realized I apparently don't know what I need.
Lookig for a plug and play solution.
Here's the setup. External fan I just need to spin without connecting it to something made in china that'll burn down the building.
