So the time has come, I’ve put both the NH-U9S and NH-D9L through their paces and while there is a clear winner in performance, they are both very worthy coolers. By today’s standards, these coolers are a bit smaller than most we see as companies lately have taken go big or go home to a whole new level. Noctua has graced us with some more normal sized coolers that still offer great performance.

Both the U9S and D9L were able to handle the heat and stayed within the limits of safety for CPU temps, which is very important, especially when overclocking. As per their standard configurations, both of these coolers only come with one fan, but adding the second fan does allow for a bit better temperatures, even if not by much. Adding the second fan onto the coolers and temperatures dropped around 2c when doing a full load test on the overclocked settings. (Ben Enos, Enostech.com)
