Mikhailtech has taken a look on a few Alpha Ramsinks/GPU Coolers from Alpha Novatech :
This is by far not a new product, but several years later Alpha is still going strong with a something that was released before anyone even thought of adding heatsinks to memory. Sure they don't look as cool as nickel plated copper, but if you want sheer performance, these will get the job done. Someone should really start anodizing them so they match red/blue/green/etc PCBs. Now that would be something.
