I agree with the 1-2mm thick part, but geez, an earbud??Apply enough thermal paste(rice grain sized) to make a layer of 1mm-2mm thick paste, any thicker will have an opposite effect and can overheat the CPU, then using an ear bud in circular rotations spread the Paste on CPU equally.
Try an old credit card/business card. Works best.
