Now, try to think how that can go either direction, it's reversible.
So you have one heated metal xfer heat to the airstream. You get hot air. But that hot airstream passes over another set of cool fins. The heat is xfered from the hot air to the cool fins.
So heat passes from one thing to another. It's not a one-way street. Heat goes downhill from hotter things to cooler things.
That's what the air bearing does, it lets heat go from one metal piece to air to another metal piece. That's how the heat crosses the air bearing.
that make sense on how heat moves from stationary part (heat absorb part) to rotation part (heat dissipate part).
at the end of the day. heat transfer heat dissipation is a matter of: total surface area x amount of air flow.
looks like CM 212 is still king for ~$30.
