The fan läßßt join the 4-Pin connector on the motherboard and rules. Of course you can do it (like any 4-pin fan) also connect to a 3-pin connector - whether it can be controlled there, depends on the motherboard. In my Asrock it did not work, so I could pair it thanks to the Y-adapter to the CPU fan. This works very well: If the CPU fan increases, also increases sensibly the case fans. A sensor cable of the fan can connect this to a free 3-pin connector on the motherboard, and so read the RPM separately. All this is shown in the manual by chart and gave me no riddles. Certainly, the part is not ground off 100%, but you usually only so once it builds a.
The cooling capacity itself is very good: Compared to my 8cm cooler housing the temperature drops by 3-4 ° C and the fan is much quieter. A certain longevity I expect because of the 6-year warranty. In summary, I would recommend this case fan for normal users and forgive because of the low price and guarantee 5 points. Hardcore gamers and absolute Silent freaks could possibly be dissatisfied with the part because high fan output then caused loud noises.
