The Noctua NH-U12S Redux is identical in shape with both the NH-U12S and the NH-U12S Chromax.Black. However, there are a few notable differences in the case of the NH-U12S Redux which will be presented in the review.
The dimensions of the heatsink are: (H) 158mm x (W)125mm x (D)45mm.
The heatsink has a single tower design and uses a total of 50 aluminum made cooling fins. The fins have a good build quality and make up a sturdy structure, however they can be bent if enough force is applied.
The total weight of the heatsink without the fan installed is 515g.
The NH-U12S Redux uses a total of four copper made heatpipes, one heatpipe less than the regular NH-U12S cooler. In addition to a missing heatpipe, the used heatpipes are not soldered to the cooling fins.
Each heatpipe has an outer diameter of 6mm and all of them are arranged into the standard U shape.
The endings of the heatpipes are completely exposed, thankfully, the endings are symmetrical and have a good design overall. This is worth mentioning as misshaped heatpipe endings will disrupt the design of the CPU cooler.
The top of the heatsink is covered by a dedicated aluminum plate which features the Redux emblem stanched into its surface. In addition, this metal plate is attached to the heatsink with four Philips screws.
The baseplate of the NH-U12S Redux is identical in shape with the baseplate used on the regular NH-U12S. However, the NH-U12S Redux has a layer of thermal compound pre-applied on its baseplate.
The baseplate itself is made from nickel-plated copper and has a smooth surface with a mirror like reflective texture.
The NH-U12S Redux uses a single 120mm Redux fan for its active cooling. The included fan is a Noctua NF-P12 redux-1700 PWM, a fan which has a minimum speed of 450RPM and a maximum speed of 1700RPM.
This fan has rubber pads only on one side of the frame, the side that makes contact with the heatsink surface. This is done to keep the cost as low as possible.
The cable of the fan is covered by high quality sleeving and the connector used is a standard 4 Pin PWM.
