Ok, So I am literally rebuilding my laptop although one part I can't find is the heat sink. I have looked up the part number which is, 682178-001 from the looks of it the heat sink would come with the fan being that they were attached, Although like others you can unscrew the fan to clean it but my heat sink pipe is bent something fierce which is where I am trying to find if the part comes with the heat sink or not.I can't access any site to get to the picks but I'm looking for a replacement heat pipe that goes from the fan to the APU, I have a DV7 7121NR Cheers
