No just anodized aluminum acrtic silver epoxied to the EK, I wish they had been copper. Those spots on the EK just seemed like they needed something and this looked cool. I've had these laying around so long I forgot where I got them (I think maybe from an old vid cooler set). It may help a little with cooling but there is no air blowing over that part so probably not helping too much. I'm glad you like it, took about a month from start to finish. Man did I miss Bioshock and CS:S :biggrin:.
