Hello everyone, i have my HTPC inside cupboard, thus when stressed it overheats. on top of the cupboard i have some slits, and i wanted to build a cooling unit to circulate the air inside. i thought of using there fans: http://www.thermaltake.com/product_info.aspx?PARENT_CID=C_00000498&id=C_00000500&name=Performance+DC+Fan-4PCS+Value+Pack&ov=n&ovid=" [Broken] i tried to connect it 8 of them with 1(A), 12(v) transformer, and it worked beautifully, problem is i have to shut them down manually. i tried plugging only 1 in with a usb to molex cable, and it just didnt get enough airflow, my guess because usb is limited to 5(v). is there any way to amplify the voltage? or if u have other creative ideas, id like to hear them :) Thank you all very much in advance, Ran A.
