The dude's at Overclockers Cafe check out the Evercooll
CUC-610 hsf. It's qutie small probably good for servers. Hmm... They're
right it does look like an Alpha heatsink!
The base measures 6mm think. It is 64 x 64mm square, with a copper inlay
that is centered, measuring 47 x 47mm square. In looking at the Alpha website,
you can see a sink that resembles is the spitting image of the CUC-610. Maybe
the same manufacturer produced the CUC-610 as does the Alpha.
