Fan Controllers - you know them, you might even use them. They are those case bay products with switches or dials that slow your noisy fans down or shut them off. The premise is you are able to use your computer quietly while writing reports, but when you need maximum cooling power for things like gaming, you turn your fans on/up even though it is a bit noisy. Most are 5.25-inch bay products, but few have occupied the spot where your 3.5-inch floppy drive used to be. Enter the Enermax 3.5-inch Fan Controller.
