Unboxing the L9i you will be amazed by the packaging and the product quality.


The Noctua NH-L9i is one of the best low profile coolers on the market. I can recommend this cooler for all CPUs with a TDP of 80 W and below such as Core i3, Core i5 and Core i7.

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 41.8 dB with 12 Volt. For HTPC or Office PCs I recommend to use 5 Volt supply voltage as the cooler still performs well but the noise-level drops significantly to 32.3 dB which is almost impossible to hear in a normal system.

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:
