According to the manufacturer, this is the newest version of their rgb fans. Therefore, they indicate that this model is supposed to be the best in their range.

I would add that I have tested the QLs on several HydroX builds with 1x360mm or 2x360mm heatsink(s) on Intel 9900k and Amd ryzen threadripper and have had no trouble "cooling" (liquid temp 30-35°) if they are not ideal they also make much less noise, the input-output orientation and placement of the heatsink matters much more.
