NH-U9S
The U9S performs quite well despite its small stature. In our dual fan configuration, cooling a non-delidded Intel Core i7-8700K at stock speeds resulted in 37-38°C idle temperatures and 68°-72°C load temperatures. This was in our In Win 301 tempered glass case. When idling on the Windows desktop and in light load situations, the U9S runs near silent.
Tempered glass cases tend to result in hotter temperatures compared to non-glass cases and when we removed the side panel, temperatures dropped 4°C on average in all scenarios.
"The Noctua U9S heatsink is a high-quality product that performs excellently, is incredibly well made and comes with a confident 6-year manufacturer’s warranty. We highly recommend this CPU cooler for those looking to cool high TDP processors such as the i7-8700K in small ITX cases like the Ncase M1. We also recommend the U9S for those who want silent system that won’t require any maintenance whatsoever." (Performance-Computer.com)
