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:
65W or less
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: "With the release of the NH-D14, Noctua brought to us a goliath of a passive CPU Cooler. It has dominated at Noctua’s top end solutions for over 4 years. One would think that the gigantism would end there. This isn’t the case as the newer and even bigger NH-D15 goes that one step further." (Farhan, Khan, TechLobby.co.uk)
