THE NH-D9L
The 110mm tall NH-D9L is also just 92mm thick and wide and weighs just 531g (with the fan).
As you can all see part of the fins is bend on the sides in order to increase airflow by keeping the air in.
Each heatsink has a total of 35 aluminum fins.
The NF-A9 92mm PWM fan can spin up to 2000RPM in order to produce up to 46.43CFM of airflow with just 22.8dBA of noise.
Four 6mm nickel plated copper heatpipes pass from the base of the cooler and through all 70 fins of both heatsinks.
The nickel plated copper base has a nice mirror like finish.
