Frostytech has tested the new Thermaltake DuOrb heatsink, check it out!

"This is where the new Thermaltake DuOrb heatsink comes in. This heatsink features twin 80mm fans set side-by-side so cooling surface area isn't sacrificed for keeping the total heatsink height under 90mm. The DuOrb is novel in a couple of other aspects; it uses a combination of copper and aluminum fins, six heatpipes and a radial shaped fins to get the most cooling surface area packed into a compact package."
