A:Answer I would cut out a space for the fans at the bottom front and very top of the unit, with the bottom being cold air intake and the top being hot air exhaust. If cutting at the top of your unit isn't possible, I would put the hot air exhaust at the front top of the unit. You will need a power supply that supports molex. If you plug the fans directly into the power supply, they will run at 100% until you turn the unit off. However, you can purchase a molex fan controller and manually adjust the speeds. I added two products that will work, but there are plenty of power supplies and 200 mm fans without LEDs to chose from. Hope this helps!
