This is one of the best coolers from Thermaltake. Unlike the 'Orb' series, the Volcano II's heatsink is based on the traditional fin-type design. The Volcano II comprises of a medium-sized heatsink with a moderately loud fan. The clip is similar to the one used in the Thermalright SK-6. You will need to use a flat-headed screwdriver. However, it's much easier to install, compared to the Orb series.

The specifications below are overrated. It spins at only around 4500rpm and it's impossible to create that much air flow (36 CFM), spinning at that speed. I reckoned that the actual air flow is around 25 CFM, about the same as the YS Tech fan.
