Performance Testing

Please refer to the dedicated test setup page as it applies to this review as well. That said, as mentioned before, I was unable to get any PWM control over these fans in time for this review and L-Connect 3 only allowed direct RPM control. As such, I ended up simply setting the fans at the usual RPM values I do for comparisons and measuring the noise level and CFM values when mounted on a radiator. Each fan was still tested separately with the average seen below, and sample variation was minimal—provided you go by the reported values in the software anyway.


So we end up directly in the comparison section here where the chosen RPM values reflect the usage scenarios most popular with watercooling even though some fans go higher, as is the case here. The charts are to be considered for comparison within this result set only and are not to be compared with results from another test elsewhere owing to different testing conditions. Note that these are average values for all samples of each fan and do not reflect any sample variation, but the Lian Li UNI Fan SL 120 Wireless continues the UNI FAN SL trend of being a weak performer as a radiator fan. In return, it ends up being on the quieter side of things along with its sibling.


For this chart, I ended up using the values above and then went a bit further to add data points above 1500 RPM to better reflect how this fan does against others across its 300-2000 RPM fan range. The zero RPM mode also worked fine when the chosen component temperature is below a specified value, for what it's worth. Here I only have three other RGB fans for a more apples-to-apples comparison in the form of the Corsair iCUE Link RX120 RGB the SeaSonic MagFlow ARGB, and the Thermaltake SWAFAN 12 RGB, with the latter being on the older side of things but still besting the UNI FAN SL 120 Wireless, as do the others. It's not a lot, and the net result cooling down your radiator and/or case will be dependent on the other components in the build, but suffice to say these are probably better treated as case fans. Lian Li's own UNI FAN P28 is the way to go for pure performance as a radiator fan, or even from a performance-to-noise basis.
