"The individual switches each can take up to 6W. In our case, the 80mm Panaflo comes in at about 2.08W. So it is well under the maximum wattage supported by the switch. Keep in mind that the faster and large your fan is, the more watts it uses. For example, the fastest Panaflo I have seen comes in at a bit over the 6W mark, so be careful on which fan you use."
