TDP guidelines & cooler height
Noctua does not specify the performance of its heatsinks in terms of maximum possible heat dissipation because the question of how much Watt (W) a heatsink can dissipate depends on various parameters such as the type and shape of the heat source, contact quality, contact pressure, thermal interface material application, ambient temperature, etc. As a result, the maximum possible heat dissipation value varies from platform to platform and between individual systems.
Please refer to the following table for how much Watt of Thermal Design Power (TDP) Noctua‘s heatsinks support on different platforms and how much overclocking (OC) headroom a given model will offer.
The indicated W value refers to the maximum recommended Thermal Design Power (TDP) as specified by the CPU manufacturer.
The overclocking headroom (OC) is specified as follows:
*** = best overclocking potential
** = medium overclocking potential
* = low overclocking potential
If no OC headroom is specified, Noctua does not recommend to use this cooler for overclocking CPUs with the indicated maximum TDP. CPUs with lower TDP can be slightly overclocked but the overclocking potential will be low.

"-" indicates that the CPU platform is not supported by this cooler. See our socket compatibility chart for details on mechanical socket compatibility.
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 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 coolers with the supplied Low-Noise Adaptors, the maximum recommended TDP and/or overclocking headroom will be lower. As a rule of thumb, overclocking headroom will be reduced by one star when using Low-Noise-Adaptors. If no overclocking headroom is specified, please choose a CPU with a lower TDP if you want to use Low-Noise Adaptors.
