Very big fan of the PC fans for air movement.I am an electronic repair technician and I have access to dozens of scrap Ps5,Xbox one And Xbox series x Fans and I have them all over my tent hardwired to 15volt power supplies.Good efficient way to move air around pennies to run on the light bill.The Xbox series x ones are the best they have a prebuilt in fan shroud that is made for moving air though tent ducts damn near
