NH-L9a TDP Guidelines

The NH-L9a is a low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first rate performance in its class, it is not suitable for overclocking and should not be used on CPUs with more than 65W TDP (Thermal Design Power). Please see the following table for our detailed recommendations and also read the explanations below:

AMD   65W or less Yes
100W No
125W No

CPU temperatures depend on various different factors, so please take note of the explanations below and keep in mind that our recommendations can only serve as general guidelines for typical setups.

1) Our recommendations are based on an ambient temperature of 25°C or less. Please ensure good case ventilation when ambient temperature is 30°C or more.

2) Our recommendations assume that the cooler is installed in a typically equipped, properly ventilated HTPC system. If you are using particularly hot components inside your system, it may be necessary to use stronger case ventilation to ensure sufficient CPU cooling performance.

3) Our recommendations assume that the fan is used with PWM control (configured so that it can speed up to 100% when necessary) but without the supplied Low-Noise Adaptor. If you would like to use the NH-L9a with the supplied Low-Noise Adaptors, we recommend choosing CPUs with less than 65W TDP.

23.09.2014 - NF-A8 FLX
Test verdict: "Mit dem Noctua NF-A8 FLX hat Noctua sein Portfolio um einen 80-mm-Lüfter erweitert, dessen Einsatzgebiet nicht nur in der Belüftung von kleinen ITX-Gehäusen zu finden ist. Durch die erbrachte Leistung kann er auch als Lüfter auf kleinen CPUs bzw. APUs eingesetzt werden, welche man z.B. bei einem kleinen Media-PC verwendet." (Patrick Seus,

22.09.2014 - PC Perspective NH-D15
Test verdict: "The NH-D15 cooler performs up to Noctua's promises, delivering top performance in most cases even against water coolers without the noise normally associated with high performance air coolers." (Morry Teitelman, PC Perspective)

22.09.2014 - NF-A8 PWM
Test verdict: "Noctua se ha sabido construir un enorme prestigio gracias a la excelsa calidad de sus productos. El ventilador Noctua NF-A8 PWM ha cubierto nuestras mejores espectativas, tanto en lo relativo al rendimiento como al funcionamiento silencioso se riefiere. Los ingenieros de Noctua han ajustado las prestaciones del NF-A8 PWM con absoluta precisión." (José Romero,

22.09.2014 - NF-A8 ULN
Test verdict: "Preislich ist der NH-A8 ULN nicht der günstigste 80mm-Lüfter auf dem Markt, dafür gehört er aber zu den leisesten seiner Sorte und wurde zudem mit einem großen Lieferumfang ausgestattet. " (Patrick Seus,
