Noctua NH-U12S redux, review: high-quality cooling


Noctua NH-U12S redux It is a new CPU cooling system that we present today in our analysis or review.

This is a new version of the prestigious NH-U12S model that we combine with a second fan Noctua NA-FK1 redux. Heatsink Noctua It has an aluminum body with excellent finishes and its vertical design allows us to fit the 120mm fan of the redux range with excellent performance and an affordable price. A system that we can use in processors with high TPD, the system of fins and pipes offers us a good margin to do OC. Let’s check now what this cooling system offers us and to what extent it can fit us.

  • Noctua NH-U12S redux can be purchased at Amazon.es from 50,10 € with free shipping for Prime customers.
  • Noctua NA-FK1 redux can be purchased at Amazon.es from 16,90 € with free shipping for Prime customers.


PRODUCT DETAILS

Specifications

Unboxing

The new Noctua NH-U12S redux It is packaged in an excellent way as is the norm in all products of the Noctua brand and to test it at maximum performance we also have an extra fan Noctua NA-FK1 redux. In addition to the standard fan we have the necessary extras to mount and install this cooling system in AMD processors, you must consult the instruction manual before starting the assembly safely.

Description

Cooling system Noctua NH-U12S redux It comes in a box with all the components perfectly protected. Fan assembly NF-P12 redux-1700 PWM with the cooling block it measures 71 x 125 x 158 mm and weighs 755 g with fan. In the lower area where the pipes pass we have a contact area where thermal paste is already applied NT-H1. In the heatsink we have a SecureFirm2 mounting plate, screws for compatible AMD or Intel sockets and the manual explains the whole process in detail. On the extra fan Noctua NA-FK1 redux we have the Y connection cable + LNA cables is an extra for those who want to limit the RPM.

  • NF-P12 redux-1700 PWM: 450 – 1700 RPM / Casquillo SSO / 120 m³/h / 25,1 dB(A)
  • Noctua NA-FK1 redux: 450 – 1700 RPM / Casquillo SSO / 120,2 m³/h / 25,1 dB(A) / Cables LNA

As we can see in the comparative table between the different models Noctua NH-U12 this version redux it simplifies some of its points such as the number of pipes, in addition, the solder between the pipes and the heatsink fins is eliminated. In this version we also do not have an LNA cable, thermal paste in a tube and compatibility with the AM3 socket is eliminated. The price is also lower, something that makes it more attractive without a doubt.

START UP

Assembly

The assembly on our motherboard of the Noctua NH-U12S redux It is very simple, we disassemble the fan, tighten the two screws and then we reassemble the fan. As we always indicate, it is recommended to progressively tighten the screws, making four turns at a time to distribute the pressure. Then we mount the second fan Noctua NA-FK1 redux and the Y-cable or additional noise reducers.

The height of this fan is 158 mm, something that we will have to take into account when selecting the box of our PC. This fan it has no compatibility problems with any type of RAM, the height of the main radiator with respect to the RAM sockets allows us to clear them without problems.

PRUEBAS HARDWARE


Testing hardware

Perform tests on the Noctua NH-U12S redux using the new AMD Ryzen 9 5900X processor that is going to demand good performance from this cooling system. We compare the thermal results of other AMD processors that we have seen in detail in their respective reviews with active ventilation.

  • Mounting: Allows mounting a 2nd fan with the included lifters / Allows it to be rotated 90º.

Temperature

We carry out several types of tests comparing the heatsink Noctua NH-U12S redux with which we have standard with AMD processors. As we see the temperature difference is objectively better than the AMD Wraith Spire fan, the differences are minimal and we have excellent ranges in any use scenario. If we add the second fan Noctua NA-FK1 redux we have an improvement in temperatures and it is recommended if we are going to perform OC.

  • Measuring temperature: 24ºC.

During the tests carried out on our equipment we have excellent results, the system maintains always low temperatures with a minimum acoustic level. The values ​​are very good improving the standard fan, the airflow is much better and it pushes it out of the box efficiently.

Noise test

The performance data of the Noctua NH-U12S redux They are excellent, as we see in basic use we are in only 18 dBA which makes it practically inaudible even though it is around 700 RPM of normal use, we reach the 21 dBA if we take it to a use higher than 50% where we have it configured at about 1000 RPM. Just taking the processor to a performance stage does the fan trigger reaching the 26 dBA, as we have seen, it is at a maximum of 1700 RPM, but it also does not generate a loud sound. If we add the second fan we have less noise because the revolutions go down to 1500 RPM in maximum use.

CONCLUSIONS

Opinion

After testing the cooling system Noctua NH-U12S redux combined with the second fan Noctua NA-FK1 redux We can say that we are facing a very good solution for any type of processor even with a high TPD. The assembly is simple and robust, it is compatible with AMD or Intel systems, it is fully compatible with all types of RAM. The materials and design of Noctua As always, they give off quality and we have the best performance with minimal noise, now at an affordable price.

As we can see in our tests, this is a valid option for all types of processors, the reduction in some of its specifications does not significantly affect the final performance. The system always maintains a fairly low noise level and only if we bring the processor to maximum performance will we hear some noise, but it is low compared to other brands.

In general the Noctua NH-U12S redux is without a doubt a excellent investment for any team, if we combine it with the extra fan Noctua NA-FK1 redux we can get even better performance.
