Unboxing the D9L you will be amazed by the packaging and the product quality.


The Noctua NH-D9L is a low profile dual tower CPU cooler. I can recommend this cooler for all CPUs with a TDP of 140 W and below such as Core i3, Core i5 and Core i7. The D9L performs very well for using only one 92 mm PWM-fan. Therefore I can even recommend this cooler for overclocking using CPUs below 100 W such as an Intel Core i7-4790K.

The cooler comes with the Noctua NT-H1 thermal paste and is compatible to all latest Intel and AMD CPUs. NT-H1 is one of the best thermal pastes on the market and very easy to apply. So if you decide to buy this cooler there is no need to buy a seperate paste.


The 92 mm fan provides a good cooling and reaches up to 43.5 dB with 12 Volt. The fan has rubber protections at the edges to lower the vibrations transmitted to the rest of the system.


I recommend to use 5 or 7 Volt supply voltage as the cooler still performs very well at those voltages but the noise-level already drops to 38.1 dB at 7 Volt and even 34.1 dB at 5 Volt.

This cooler is perfect for small HTPC or miniITX systems. You won’t have any compatibility issues on the memory or the graphicscard.

Noctua has a great compatibility list on their website which you might want to check:
