It took years, but finally DeepCool managed to modernize its fans in the 140mm format as well. The DeepCool FT14s present themselves with very attractive specs – both the airflow and static pressure are above standard, but the key is how these fans will fare in practice compared to competing models. What makes the FT14 visually different from those at first glance is that you can see inside the motor.
Results: Frequency response of sound with a dust filter
Measurements are performed in the TrueRTA application, which records sound in a range of 240 frequencies in the recorded range of 20–20,000 Hz. For the possibility of comparison across articles, we export the dominant frequency from the low (20–200 Hz), medium (201–2,000 Hz) and high (2,001–20,000 Hz) range to standard bar graphs.
However, for an even more detailed analysis of the sound expression, it is important to perceive the overall shape of the graph and the intensity of all frequencies/tones. If you don’t understand something in the graphs or tables below, you’ll find the answers to all your questions in this article. It explains how to read the measured data below correctly.
The vast majority of fan sound operates in the 70–7000 Hz band. You can virtually ignore frequencies above 7000 Hz, they reflect electromagnetic noise from the measurement chain. This (electromagnetic noise) also extends to frequencies below 70 Hz, although there is still aerodynamic noise at these frequencies. These bands (below 70 Hz and above 7 kHz) could be safely “cut out”, but we do not. Just in case one of the fans does have an anomaly that needs to be controlled and visualized.
Note: For these measurements, a plastic filter is used, which, compared to a situation without an obstacle, bends the sound considerably more than a non-obstructive nylon filter.

Why is there a missing value sometimes? There may be more reasons. Usually it is because the fan could not be adjusted to the target noise level. Some have a higher minimum speed (or the speed is low, but the motor is too noisy) or it is a slower fan that will not reach the higher decibels. But the results in the graphs are also missing if the impeller is brushing against the nylon filter mesh. In that case, we evaluate this combination as incompatible. And zero in the graphs is naturally also in situations where we measure 0.00. This is a common occurrence at extremely low speeds with obstructions or within vibration measurements.
That’s unexpected results. I would have guessed it performs better on radiators than vs no obstacles, but it’s the opposite!
Is the buzzing noise only present under ~750 RPM, or is it there across the whole speed range? On higher dBA settings, I can still see some of the peaks at 1-2 Khz.
There will probably be some buzzing at higher speeds, but because of the diminishing contribution to the total, in contrast with the aerodynamic noise (which drowns out these sounds) it fades out alongside other, significantly noisier frequencies. The buzzing is, of course, more pronounced at lower speeds (like ~750 rpm), at the limit of minimum rpm. But we don’t have a spectrogram for those. 🙂
Noticeable buzzing noise is present till the 20% of PWM or ~660RPM, have three of those on a 45mm rad :/
I mean buzzing is starting from 20% of PWM and 660RPM, and after 800-900RPM buzzing noise doesn’t bother because airflow noise is louder.
Little correction 🙂
Thank you for sharing your user experience. Yes, the buzzing noise also occurs at higher speeds, and the question is to what extent it is disruptive at which speed compared to the aerodynamic noise. This can be evaluated differently by everyone, as it is subjective.
