Alphacool Rise Aurora 140 mm ARGB fan in the test – It blows (almost) all (s) and dusts even the thickest radiator
A speed range like an XXL suspender, paired with a lot of pressure and throughput that does not break even on the thickest radiator – the Alphacool Rise Aurora 140 mm is therefore recommended as a real radiator fan. The appearance is more than just restrained, it is downright brutal. Today’s test will have to clarify whether and with how much additional sound pressure this might have to be bought, but I can spoil the fact that there are currently hardly any comparable offers for the generation of a cold air front outside of industrial fans.
No, of course it is not the really quietest fan in all the tests with such a design, but despite a lot of torque it is anything but cheeky. The EKL Wing Boost 3 tested last time, on the other hand, was only a mild breeze and a straight marketing lie, because compared to this, the measured values and data sheet have been correctly matched again for a long time. Which means that the manufacturer’s direction would also be clear: static pressure until the doctor comes and a lot of throughput, with everything being easy to control over a very large speed range. Fan stop, quiet or blizzard, everything has somehow been included and you can decide freely.
The fan uses the classic sleeve bearing, which does not necessarily have to be a disadvantage, because the OEM has decades of experience in this regard, but it could have been nicer. The frame is simple, very torsion-resistant and, together with the hub, houses a total of 24 ARGB LEDs that can be individually controlled digitally. By using translucent plastics, you can see a very even light image without individual hotspots for the LEDs. The shape of the impeller follows the current trend and relies on specially shaped tear-off edges.
The decoupling with the attached rubber applications is neatly solved, especially since they do not twist when the screw is tightened. The gaps and surface finish are very good. The power consumption is quite steep at full speed with 6.6 (without LED) watts, but that’s the toll that you have to pay for high performance. First of all, the key data for better comparability with the later measurement results:

On the next page you can see how and what we test and why. Understanding the details is extremely important in order to be able to classify the results objectively later. The differences between many models are more in the details and there can hardly be THE best fan for all situations. There is a certain optimum in every situation and of course there are also good all-rounders. But they usually have their price. If you are planning specifically with 60 mm radiators, for example, you can perhaps save money by choosing the best model for your application, which might not do so well as a case fan. And vise versa, of course.
