Alright so the story goes a little like this, the Noctua NH-D15S is pretty much similar to the NH-D15, lacks one fan is a teeny tiny bit less in performance yet was one of the most silent solutions we have ever tested. Seriously, you'll have a very hard time hearing this unit as it was simply completely silent based on a normal RPM profile managed in the BIOS by the ASUS motherboard. With a D15 tweaking your CPI remains a viable options as well. Our Core i7 4790K is a bit of a bitch to overclock with heatpipe cooling, the Noctua makes this possible though. Up-to 1.30~1.35 Volts this cooler has no problem in terms of noise and cooling performance under the condition that you do not stress the processor for hours 100% continuously. But yeah we measure 34 DBa at defaults under processor load (and we consider a cooler to be silent if it stays under 39 DBa) and overclocked at 1.35 Volts on the CPU we merely reach a measly 36 DBa.

"It's the top-end Noctua model with just one fan, nearly equally as good as the two fan version. You just can't complain here." (Hilbert Hagedoorn, Guru3D.com)
