The boys at Overclocker Cafe look at the new Z-Bra Hybrid Copper/Aluminum heatsink.
They seemed to like it quite a bit, check out their results here.
The copper/aluminum construction isn't the only thing that
sets this heatsink apart. As you can see the sink has a half round shape to
it created by the cooling fins. While most heatsinks have fins that either flare
straight up or off at an angle, 3a Cooler has designed the Z-Bra to curve away
from the base and up to the fan mount.
