Hardware Pub have posted up a review of the Thermaltake Volcano 7+. Heres a Quote:

    "This heatsink forges a new path for the Volcano line, being the first to strut its stuff with an entirely copper sink, rather than an insert like the original Volcano 7, and both Volcano 6 Cu models. The sink has 36 fins for maximum surface area exposed to the fan in a rather apocryphal naming scheme called "tiny fin" technology. How technological thinner fins are is is rather questionable, but they are nevertheless a benefit."
