Cooling Efficiency vs. Thermalright IFX-14

Well, now we have to see how the new Noctua NH-D14 cooler performs against still the best air cooler out there:

As you see, the new Noctua flagship solution is one step ahead of Thermalright IFX-14 in all test modes. In quiet mode with one 140 mm fan NH-D14 is 3°C more efficient than the competitor, and in almost all other cases – 2°C more efficient. With two Thermalright TR-FDB fans that suit IFX-14 the best, the difference lowers to 1-2°C, but the victory still stays with Noctua NH-D14. The table below shows the detailed results for your reference:

During the maximum overclocking tests the Austrian newcomer was ahead again:

Noctua NH-D14 
(2 TR-FDB 2070 RPM)

Thermalright IFX-14 
(2 TR-FDB 2070 RPM)

I will be brief about the acoustic performance of Noctua NH-D14: up to 1000 RPM the cooler was extremely quiet and at maximum rotation speed the noise was moderate. Most interestingly, at up to 1000 RPM we couldn’t detect any acoustic differences between NF-P12 and NF-P14. At higher speeds 140 mm fan is a little noisier, but mostly because of larger air volume going through. We are going to take a closer look at the fans performance in the upcoming fan roundup and now it is time to draw some conclusions.
