Conclusion

With the NH-U9B Noctua developed a very good performing cooler and considering the compact size of the thing the performance is even better!

The very well thought mounting concept allows the installation of the NH-U9B with backplate not only on Intel platform it also provides AMD platforms with the feature. Like this the cooler fits perfect on both platforms.

The well thought design of the aluminium fins gives you an adequate performance for standard PC systems.

Subjectively we categorise the fan at 12 volts as audible and under 6 volt conditions it is subjectively silent. With the Noctua NH-U9B you can easily drive the fan with only 6 Volts and there is still plenty of performance.

We can recommend the Noctua NH-U9B for every single purpose! If there is plenty of space we can even recommend using it in a HTPC at 6 volt. Only the not so low price tag is damping our euphoria but considering the the very high quality of every single piece included in the delivery it is absolutely legitimate.

You can buy the Noctua HN-U9B for CHF 94.- at Digitec.ch.
