You guys are harsh, I noticed a 10*-15*F difference with my volcano 9. then again I also use Artic silver and a Torando fan with duct mod.

Yes we all know I Ducknapped DuckWarrior. Hey I could have a duck in my comp that might be a interesting way to hide a RAD, in a plastic duck, probly not to good for termal trasnfer though.
