"Can you use the grease to cool one's head?" I asked out of curiosity.
Ever the geek, Dwayne explained that the grease comes in two types: the conductive and non-conductive. The conductive type contains silver, copper and aluminum, so it should be used carefully because it can cause electric shocks when applied to computers. On the other hand, the non-conductive type is composed of zinc and silicone so you can't use them for the human body.
