The NH-L9x65 passes our performance test with flying colors, averaging 64.4 degrees Celsius under load from our Aida 64 run, which is fairly comparable to any load coming from a CPU intensive game. [...] The included fan provided by Noctua has the model name NF-A9x14 and is available for purchase for $19.99 (Newegg). Being slim can actually help reduce the noise caused by the fast moving small blades of smaller fans proven by Noctua’s 92 mm fan almost beating any other fan in our single fan noise measurements test. Most notably it was 3.6 dB lower than the Intel reference cooler at 100 rpm, which is a measure of improvement. These are great number for such a small fan.

"In reference to it’s competition, the Noctua NH-L9x65 is a top of the line cooler with great technical features such as advanced Flow Acceleration Channels that allow the blades of it’s 92 mm fan to be more airflow efficient and reduce noise caused by the vortex phenomenon. It has major gains when compared to the Intel stock cooler in terms of performance and noise, and it is a very decent performer as it managed to cool our I5 4670k with no major hiccups. All of that topped with Noctua’s 6 year warranty and outstanding customer service make the NH-L9x65 a very good performer." (Julian Duque, BenchmarkReviews.com)
