Noctua NF-A14 PWM: Relevant even after a decade

Results: Speed

There aren’t many 140mm fans that are more popular than the NF-A14 (PWM). This Noctua model has maintained that for a long time, for over a decade. In the meantime, naturally, a host of newer competing solutions have come along, and the question is how Noctua’s still-flagship 140mm fan will hold up against them in the present day. By analyzing the NF-A14, we’ll also shorten a bit the interminable wait for its successor.

Results: Speed

Note: The stated speeds are measured in a non-restrictive, obstacle-free environment. With obstacles present, the fans will be slowed down. The degree will vary fan to fan but the achieved speeds will simply be slightly different. They are lower mostly in modes normalized by different noise levels.









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.

DeepCool FT14: More revealing (than others) and more capable

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. Read more “DeepCool FT14: More revealing (than others) and more capable” »

Noctua NF-A14x25 G2 PWM: Finally a first-class 140mm fan

The range of 140mm fans is now expanded by the Noctua NF-A14x25 G2 PWM. The wait for this model was very long, but finally, after various hardships, everything was brought to a successful end. This, by the way, is also indicated by our in-depth tests, from which the NF-A14x25 G2 fan takes away the “best” results across many usage scenarios. This is also due to the significant innovations in the aerodynamic design. Read more “Noctua NF-A14x25 G2 PWM: Finally a first-class 140mm fan” »

We wrote 7 years ago. Tests you may have overlooked

Some articles become obsolete faster, others are relevant for a long time. Such, more durable ones usually do not focus on a specific product, but on a topic as a whole, with a pinch of generality. Articles like this have always been given space around here, since the beginning of HWCooling, and it probably doesn’t hurt to bring them up again. Well, at least as part of this selection which would be a shame to miss forever. Read more “We wrote 7 years ago. Tests you may have overlooked” »
