The product was easy to install and the connections to the plug my existing fan control were a breeze. The cables were long enough and the included mounting hardware (screws) fitted.
In operation then I could see that the fans exude a delightfully poisonous green light. Unfortunately, it also comes to a significant fan noise. I have in the housing three fans (2x Aerocool, 1x beQuiet) and the beQuiet Dark Rock Pro 3 installed with 2 fans. If I let all run simultaneously in medium speed, these fans, is already a single manual feed switched Corsair CO-9050037-WW clearly heard case fan out. Turn to all four Corsairs moving though a lot of air, disturbs of the noise but very (even at 50% capacity).
Since I do not necessarily need this fan, I let them therefore unfortunately mostly off, although the appearance speaks against it! One must, of course, the shimmering disco effect, which produce the LEDs thanks to the blades like.
Note: If you blow so large amounts of air into the PC, you should think about the use of filter bars on the fans (come with me yet), otherwise make the dust bunnies on the CPU soon barbecue!
Conclusion
Positives: uncomplicated installation, good workmanship, strong light effect, significant air movement
Negatives: Volume
Fan can be quieter (also with LED ;-))! But since I rarely use a headset and ambient sounds are simply annoying two star deduction.
