Noctua NH-D14 CPU Cooler Revisited in 2014

By: Chad Sebring | Editorials in Cases, Cooling & PSU | Posted: Jul 2, 2014 2:08 am

Test System Setup




I would first like to thank ASUS, InWin, Corsair, and Fractal Design for supplying products for me to test with.


To see our testing methodology, and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article.



Thermal Results




As always, we start off with the stock settings at loaded levels. Here we find the 52.25 degree results to still be very good, but almost a full three degrees behind the NH-D15. While we know the D14 still can stand with the group at this level, let's apply the overclock and see how well it handles business.




In the overclocked testing, we found the NH-D14 reporting an average of 72.5 degrees. In today's market that is a pretty average result, but we see that the NH-D14 still stays right around three degrees behind the NH-D15.


While not a huge jump in performance, the improvements made and efficiency gained in the D15 could mean a jump to the next multiplier for your CPU, and the cooler could handle it within comfortable thermal range.



Noise Level Results




These results differ from the original drastically, and we can only assume it was reverberations in the hot box causing those increased levels. What we find in an open air environment is that this Noctua D14 fell right in line with the rest of the coolers, as we would expect. With only 7.5 Volts powering the fans, we found the 120mm fan spinning at 870 RPM, and the 140mm spinning at 880 RPM. Combined, they produced a 28 dB reading on our meter.




Once we had the fans running on 12 Volts, we found their speeds increased to 1360 RPM on the 120mm, and 1280 on the 140mm fan. Again, combined, they only produced 44dB of noise. Once inside of a chassis, users will be hard pressed to hear much of anything with the motherboard and its PWM functionality adjusting the fans as needed.
