The pads are rated for a specific thickness. If they thick, the data is going against you. If you need better cooling, the case needs aditional fins and it should be mechanical precise in order to be able to use thinner silk pads. In passive cooling, to get decent temperatures for the chip with a low surface heatsinks, 5 Watts is a real challenge (from my experience).
