  Power usage 
 Date Written 
I A Jan 28, 2011, 11:31pm EST Report Abuse
I am making a cooling pad, so i am using 2 antec 3 speed system blowers which use 3.6W so about 7.2W together and then two 40mm 2 Pin 12V Cooler Cooling Fan. all of these going through 4pcs SPDT Toggle switch on/Centre off/on 3Pos. MTS103. so my question is do i need a circuit board and how much power or what type of power adapter would i need to use to allow fans to run at a nice rate.

you could prob get the fans moving with a cell phone charger (~5-6V) but a 12V would spin em faster

you would need to cut some cables and attach some wires... but it works

There are also some Power Supplies/Transformers you can purchase which allow you to modify the voltage, for example, this one has 3, 4.5, 6, 7.5, 9 or 12VDC requiring up to 1000mA:

It also provides more than enough current for all those fans (and some more ;) )
