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.

Test verdict: "Testen af denne køler gik rigtig fint. Det er ikke en køler, der er beregnet til high-end overclocking, men standardfrekvenserne klarer den helt uden problemer." (Kim Monberg, Tweak.dk)

Test verdict: "Both of these coolers can handle a very surprising load for their size, and may well be setting a new performance standard for their size under heavier loads. I walked away very, very impressed." (George Cella, HiTechLegion.com)

Test verdict: "A Noctua NH-L9x65 egy kimondottan hasznos processzorhűtő ha HTPC építésében gondolkozunk, hisz olyan helyen is alkalmazható, ahol magas profilú hűtő használata nem lehetséges, egyéb alacsony profilú megoldás pedig a memória bővítőhelyek kihasználhatóságát akadályozná meg. Az NH-L9x65 hűtési teljesítménye a gyári hűtésnél hatékonyabb, annak ellenére, hogy jóval a alacsonyabb működési zajszintet produkál." (Kocsis Bence, Rendszerigény.hu)

Test verdict: "This is one low-profile cooler that has touch-the-sky performance and not just reaches for the bar, but sets a new one entirely." (Ron Perillo, Modders-Inc.com)
