The fanless spinning heatsink: more efficient, and immune to dust and detritus
Two points of confusion (for me, at least) which the article doesn't satisfactorily alleviate: first, how can something dissipate heat effectively when there is an air cushion between the base plate and the cooling vanes? And second, how is this device "immune to dust and detritus"? For instance, it seems like dust could easily enter the thin air cushion layer and cause all kinds of problems.<p>Can anyone help me overcome my ignorance and understand these points?
