The Lian Li Unifan SL-INF120 are supposed to replace the current and already tested Uni Fan SL120 RGB, and they have meanwhile triggered a certain hype in the community thanks to the daisy chain used. Lian Li has once again reworked the exterior a bit (endless mirror design on two edges as well as on the impeller) and also given the fan slightly higher speeds. Otherwise, I can already spoil that most of the data in the overlapping speed range also remained identical, so that one can speak of a largely adopted fan design here.
At around 30 Euros for a single fan and around 95 Euros for the three-pack with a matching controller/hub, the price is already in the upper class and practically also above a Noiseblocker BP12x-PS-BL PWM ARGB from Blacknoise, which is known for throughput and running culture. Lian Li focuses more on the luminosity, which is of course the kicker for the target group. The price, which is about 5 Euros higher compared to the older model, is a self-confident statement, whereas the omission of cables when mounting the device on a radiator due to the daisy-chain is of course still a really strong argument. Click and ready, it doesn’t get any nicer than that.
The black or white frame (there are two variants) is quite plain despite the mirror inlay and the aluminum applications on the edge. It has a usable decoupling and a neatly inserted outer ring for the optics for the two visible aRGB strips in each case. The rotor is also translucent and carries aRGB LEDs. The fan again relies on a usable hydrodynamic plain bearing (FDB), which is also to be expected in this price range and did not leave a bad impression.
Regarding the engine noise, which is independent of the bearing, I have but later various entries to the slight humming in some speed ranges. The weight of 210 grams is not bad, but it is 22 grams less than that of the predecessor and might also be at the expense of a built-in magnetic ring. The rotor inside has a diameter of about 10 cm, which is due to the illuminated ring.
The manufacturer specifies the thickness (installation depth) with 25 mm, which is unfortunately wrong and can lead to problems when installing in tight systems, since it can e.g. lead to collisions of top-mounted radiators with the VRM coolers of the motherboard. We measured 27.4 to 27.5 mm, which is significantly more!
The gaps of 1.5 to a maximum of 1.7 mm between the rotor and the frame are quite good and the surface finish is definitely not objectionable. The power consumption of 3 watts (measurement) for the fan (without RGB) is relatively high at full speed, but it is slightly lower than the old fan.
The specified 2-year warranty certainly satisfies the legislator, but unfortunately not more, especially since the burden of proof reverses after 6 months anyway. Other providers are now much more accommodating in this respect.
For the curious, here are some excerpts from the data sheet, which we have of course also checked.

For all those who still need the media-compliant buzzwords and features and want to find out how easy it is to do all the cabling, I would simply recommend the media kit, where you can really find everything that has to do with the luminosity, optics and condensing:UNI FAN SL-INF_Media Kit
On the next page you will first see how and what we test and why. Understanding the details is incredibly important in order to be able to objectively classify the results later. The differences between many models are more in the details and the best fan for all situations can hardly exist. There is a certain optimum in every situation and, of course, good all-rounders. But they usually have their price. However, if you are planning very specifically with 60 mm radiators, for example, you might be able to save money by choosing the best model for your intended use, which might not perform so well as a case fan. And vice versa, of course.
