Noctua NH-U9B CPU Cooler Final Thoughts:

The last Noctua cooler I reviewed (NH-U12P) raised the bar when it comes to air-cooling, and when I received the NH-U9B I was very optimistic about how it was going to perform. Comparing the two against each other really isn't fair, since they are both aimed at a different consumer, but a lot of the things I really liked about the NH-U12P, Noctua was able to incorporate into the NH-U9B, and that is a good thing. Things such as great accessories, easy installation (even though you have to remove the motherboard), and sturdy design really help make this a great cooler. The fan adapters that come with the NH-U9B are a nice feature, a PWM fan might be preferred by some, but in applications such as HTPC's, users are going to appreciate the option to slow the fan down to ~1100 RPM and make the fan virtually silent and not have it spinning up and down. Even with no adapter and the fan spinning in the ~1600-1900 RPM range its not overly loud by any means, but with the side off your case you can hear it, and for the silent PC enthusiast that might be too much, even though the average user would probably never hear it and chances are good that in an average PC there are going to be much noisier components anyways.

There is a bit of a performance decrease when going from the NH-U12P to the NH-U9B; however that is to be expected since the NH-U9B's heatsink is quite a bit smaller in size and also features a smaller fan. When comparing this cooler to other coolers with 90mm fans, it does very well and if you've got a small case, or not a lot of room for a cooler, this would be a great choice. The performance didn't set any records, but for smaller cases that aren't able to support a big heatsink, the NH-U9B could be just what you are looking for.

At the end of the day it's pretty easy to give this cooler our "Top Pick" award, and if you need a cooler that will fit into a smaller case, the Noctua NH-U9B is a very good choice.


  • Very Quiet at Low Speeds
  • Good Performance
  • Great Accessories and Manual Included
  • Reasonably Priced
  • Fits into smaller cases that cannot support a big heatsink and fan



  • None
