Do those chips have cocoa butter listed as an ingredient? Most are not real chocolate. It is possible to avoid the tempering process in real chocolate if you never exceed a certain temp when heating and I think that temp is 90 degrees.
Real chocolate will have a rubbery, non- set texture if not tempered. Might work in a candy bar shape, but it won't come out of the mold for shit and..well, ..it's rubbery.
But to temper.......Melt 3/4 of the real chocolate in the double boiler, take it off the heat and put the remaining 25% in there and let that melt into the heated chocolate. Then you need a candy thermometer, beacaus you are going to pour when it reaches the correct temp........which again I think is 90. Number may be off but that's the process. Melting removed the crystalline structure, tempering puts it back and lets the chocolate finish hard and smooth.
