NH-L9a TDP Guidelines

The NH-L9i 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 be used with care 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:


Intel
Sandy Bridge  
65W or less Yes
95W Yes
Recommended with good case ventilation only.
Intel
Ivy Bridge  
65W or less Yes
77W Yes
Recommended with good case ventilation and Intel Turbo Mode disabled only.
Intel
Haswell  
65W or less Yes
84W Partly
Recommended with good case ventilation, Intel Turbo Mode disabled and typical workloads only (not recommended for continuous 100% load on all CPU cores).


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. If your ambient temperature is significantly higher (30°C or more), we don’t recommend running the NH-L9i on 84W Haswell, 77W Ivy Bridge or 95W Sandy Bridge CPUs. For all other setups, 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-L9 with the supplied Low-Noise Adaptors, we recommend choosing CPUs with less than 65W TDP.
