What is fascinating about the Arctic P14 is the particularly high contrast of price to (cooling) efficiency. These fans are among the cheapest, while at the same time achieving top results with respect to all 140 mm fans in terms of airflow per unit of noise. And that’s even through obstacles. Arctic has made almost the maximum out of the funds available to produce the fan, and it is definitely worth it.
Airflow per euro
Explanatory note: The following charts will give a quick overview of the airflow rate per price unit. We can thus talk about the coefficient for the price/performance ratio. This is the ratio of the measured airflow rate in m3/h to the fan price (in euros) multiplied by 1000. This is specifically so that the results do not start with unflattering zeros.
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.
These results are more or less useless if I just want an answer to a simple question. How loud are these fans?
I have another simple question for you.
How deep is the sea?
…Both questions are, besides being simple, also silly. (No offense) 😉
Just as it depends on where the depth of the sea is measured, it also depends on what kind of noise corresponds to what kind of airflow.
If you are only interested in noise at max RPM and you are not using regulation, then look at the last two graphs (max airflow and corresponding noise)
I don’t think I fully understand your question. Can you please elaborate? I’ll be happy to answer in detail. In case you mean noise level at maximum speed, then the corresponding graph is at the end of each chapter. Click through the 14. to 19. chapters and you’ll receive an answer to your question. Noise level, of course, also depends on the obstacle a fan is facing. 🙂
