Features

The Noctua NF-A12x15 brings a plethora of features to the table including its Ultra-Tight tip clearance of 0.5mm which improve the overall air pressure. This is possible due to the Sterrox material used in the 7 fan blades which reduces the Impeller Creep and allows for a tighter fan design. Once you pick up the fan, you can instantaneously notice the weight difference between the NF-A12x15 and a typical case fan. These fans are made to provide exceptional airflow within your PC, as they have a max RPM of 2000 with an acoustical level of 22.6 dB. If acoustics are an issue, you can use the Low-noise adapter (L.N.A) to bump it down to 1700 RPM which will produce an inaudible level of 18.8 dB.



Benchmarks

PC owners always try to achieve the lowest temperatures they can to not only overclock their hardware to its full potential but also increase the life expectancy of their components. However, in extremely hot climates, keeping temps below the red line becomes an arduous task which is where these enthusiast grade components become pivotal. To ascertain whether Noctua NF-A12x15 are worth the cost, we will be be comparing them with a few locally available fan offerings to see if there is a difference in temps in the hot climate of Pakistan.

The fans under scrutiny include:

  1. Noctua NF-A12x25
  2. Thermaltake Riing 12 Sync
  3. Cougar Vortex SPB 120
  4. DIY

In order to garner the data, each set of fans were tested thrice. Each run entailed a 10 minute stress test on AIDA64. The ambient temperature was closely monitored to mitigate any inconsistencies within the results. Therefore, 35.7c was maintained throughout the testing period.

The results are presented below:

The results indicate the NF-A12x25 managed to keep the Ryzen 7 2700x the coolest at 86c during a synthetic stress load. The Noctua NF-A12x25 were running at their maximum 2000rpm. In terms of comparison, only the Thermaltake Riing were able to keep up a good result at 87.3c at a maximum RPM of 1500. The Cougar SPB 120 and the DIY fans presented a poor result where the Ryzen 7 2700x crossed the 90c mark.
