Just to clarify things about the AS products,
Arctic Silver II, III & Arctic Alumina are thermal compounds
Arctic Silver Thermal Adhesive & Arctic Alumina Thermal Adhesive are Epoxy
Hopefuly you don't get them mixed up when ordering them. Way too many people interchange the product names that they make a mistake when ordering.
One thing you have to consider when using thermal compound is that they require a certain clamp force for them to work properly. Thermal compound in the center & dabs of superglue in the corners doesnt nearly work as efficient because of the weak clamp force, its next to useless really. If you want it to be detachable use 1 part Epoxy to 1 part thermal compound by weight. When you do this modification be it permanent of not you do not have the right to RMA the product once it goes bad because you already have voided your warranty, live with it or don't mod it.
