This is a remix from [SethBon fan](https://www.thingiverse.com/thing:3079064) I've done some modifications to add a USB-C power delivery chip adapter to put 12v on the fan from usb-C! It's more common to have a usb-C charger/dock-in/battery than a DC-jack power nowadays! My fan is to loud at 12v, with the chip I set it to 9v and it's perfect on the desk! It works on classic 5v usb too with this chip. A upgrade can be to put a switch on the box to control one of the 3 dip switch to pass on 9 or 12v or let to 12v and [add a PWM controller for the fan](https://www.aliexpress.com/item/1005004904458737.html) Required hardware: (1) 140mm fan (8) [PC fan screws](https://www.aliexpress.com/item/1005003576210952.html) 5x10mm (1) 12VDC power adapter (1) [USB-C Power Delivery adapter](https://www.aliexpress.com/item/1005004150207130.html) (1) [DC barrel jack 5.5x2.1mm](https://www.aliexpress.com/item/32883658107.html) - panel hole 8mm diameter (1) [Power switch](https://www.aliexpress.com/item/32873386670.html) - panel hole 12mm x 18.7mm (1) 3-pin or 4-pin fan connector or simple DIP PIN Wire and soldering tools (Optional) Heat shrink tubing (Optional) Carbon filter
