Amps make heat, thats what they do //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif It will only turn about 75% or so of the current it draws into power, the rest will basically turn into heat which *should* get convected to the heatsinks and then disapated into the air.
