Carbon fiber heat spreader on Geil?

Geil is good memory. I have a system at home running a pair of 512s overclocked and they run great. I'm not sure about to whole carbon fiber heatspeader, sounds like a gimic to me.
 
I don't see why anyone would want to put carbon fiber on their heat spreaders, are you sure it's not just a paint scheme or something?

Anyway, I've heard it's pretty good.
 
Carbon fiber technically can lower the heat of a module, up to almost a 20 degree difference compared to the standard copper shields. But carbon fiber is also very, very fragile, and it doesn't look like OCZ is using pure carbon fiber for their shields.....
