Excellent! Will never use another brand CPU cooler for a high end air solution! Small but powerful!

Excellent. Configurable, with top mount 120mm fan removable for use in small cases (Y-Split Cable and Low-Noise Adapters included). I had room enough in Node 605 to use both fans.

Wish I could give it 10 stars.

Was getting 65°C with Intel stock cooler while playing FIFA 16, and changed the CPU cooler to Noctua NH-L12 and now I am getting 23°C while playing the same game. Don't think I need to add anything more.

Great cooler, quite compact. Very silent, almost inaudible. It is compatible with the rest of my hardware, but not in all 4 orientations.

Never goes over 45 Celsius even in prolong gaming load. No idea what kind of sorcery is that.

Much quieter and cooler than the stock. Also works great with a NZXT Aer fan

I originally bought this for a micro-ATX OEM case with the low profile, top down fan, and low noise output features in mind. For my Ryzen build I originally put in the stock Wraith Spire because it was ready to go and I hadn't sent away for the AM4 bracket from Noctua yet. While the Wraith Spire performs admirably for a stock cooler and is remarkably quiet even over 2,000 rpm, I just don't think it's adequate for the Ryzen 1600 CPU unless you either keep it at stock speeds or have a nearly open case with respect to airflow. Wanting to overclock to 3.8 GHz in a moderate airflow "silent" case, I decided to install the NH-L12 and see if it would help. In a word, yes. Temps are down about 8 degrees and it's still quieter than the Wraith Spire. Even with stress testing (Prime95, AIDA64, RealBench) the CPU usually stays under 76C. BOINC and some hot weather can still see 85C but I can open up the case a bit if needed. I'm hoping some 140mm Noctua fans at the intake instead of the stock case fans will help that, and long term I might even upgrade this cooler to the NH-U14S, but for the meantime this top down cooler performs well enough that it will probably stay in my build for a while to come.

Amazing little beast! Can't say anything bad about this.
