The specifications are about the same as for the standard NH-U12A cooler version. We receive a top-quality cooler with two 120mm high air pressure and quiet fans in both cases.
With the premiere of the NH-U12A version, Noctua added accessories to its offer. We can now enjoy additional heatsink covers in various colors and replacement fans with rubber anti-vibration pads. My personal favorite is a white heatsink cover. It would be even better if there were white fans available. It’s a tip for Noctua that probably more users wish to see white fans.

On the next page, we will look at the NH-U12A cooler itself.
