FrostyTech posted a review on the Thermaltake SpinQ Heatsink

Thermaltake's SpinQ heatsink is undeniably good looking. It stands 152mm tall and is made from nickel plated aluminum fins soldered over six copper heatpipes. creates an eleven-sided helix that resembles a cheese grater on steroids. Nestled in the middle is an 80mm diameter, 85mm long squirrel cage fan that draws air in through both center openings and expels it out in all directions through the 20mm wide circular cooling fins.
