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:

    Can I overclock an i5 7600k or 6600k with this cooler?

    You cannot effectively overclock the CPU with this cooler. It struggles to keep things cool at stock settings & is only rated for 95watts TDP. The author of this piece seems to be a Noctua cheerleader. I have one of these coolers. Sure, it’s pretty, but a cooling “monster” it isn’t. For starters, the whole cooler is nickel plated. Nickel conducts heat 4X less effectively than copper. Why they would use copper “heat-pipes” and then coat them in something that doesn’t conduct heat as well as copper is puzzling at best. Even if they wanted to coat them to look better (what Noctua told me. it also begs the question why their fan color choices are so ugly?), why nickel clad the base that contacts the CPU heat-spreader? If you look at the base of other heat pipe-based coolers, they’ve made it a specific engineering design decision to make sure the heat-pipes contact the CPU heat spreader directly. I also would disagree with the author on the noise level. I have dual fans on mine and I run it at 100% 100% of the time and it’s still really quiet. Maybe I just have a good case, because the difference between his quoted running the 12volt fans at 7VDC or 5VDC is weird, as these are PWM-controlled fans. Voltage changes aren’t the default mechanism for controlling the fan speeds, Pulse Width Modulation is. I didn’t whip out my dB meter to verify the claims of 43dBM, but I can tell you the difference between running the fans at 50% and 100% is like the difference between shhhhhhh and shhhhhh to my ears. Something is amiss here, and “Something is rotten in Austria.”
