The Auras CTC-868 heatsink
closely resembles the Zalman
CNPS9700 heatsink, with one major difference. The 570gram Auras heatsink splits
into three sections, connected by four heatpipes, allowing the user to better
direct airflow according to the manufacturer. With two 92mm fans aimed
back-to-back airflow could be a little odd though.
The Auras GTO-709 heatsink
is the best looking solution out of
the gates in our opinion. Based on the popular 'tower' design, airflow is
smooth, thermal via's are direct, and weight is kept down to 415 grams with a
92mm fan. The Wave-fin
design (à la Thermalright
) is intended to create a spiral airflow pattern within the heatsink and
thus reduce aerodynamic drag. The fan is also mounted on a couple of
rubber screws to absorb vibrations.
The Auras GTO-990
is a self-contained watercooling
system. We've had mixed results with this class
of CPU heatsink in
the past. They tend to be more complex to build, thus more
expensive to sell. The idea is novel, but limited heat exchanger areas
often constrain thermal performance. Auras' unit has a
non-evaporation joints, metal tubing, and a small reservoir of glycol-based fluid. The cooler weighs 551 grams, ships with a 92mm fan, and a low noise ceramic bearing 1400 rpm pump.
