Video at Amazon.com View unpacked soon as I can tell at a glance - very good workmanship - higher quality plastic than you the of the "little ones" 8 cm parts (red, blue - the cheap halt) knows. At the end of the stylish silver power cable, there is a 3 pin connector (for connecting to a 4 Pin - do you need an adapter). Clear I had that part equal to test and it had installed in my Aerocool housing for test - turned - Wow and dung - Wow, because the part really a lot of light (with 15 LED diodes) are in fact so much that my UV cathode not come more to application - I'd not really thought - why manure - can the part but not help it. On the blades themselves are no LEDs means the bodies are covered in silver and reflect the Leds. The packaging which is less than 15 decibels - but honestly I could hear nothing since. With 750 revolutions that part is certainly not the fastest but it still shoveling enough wind in the machine. With the Twister Bearing, so Twister bearing technology a good piece to an operating time of 100,000 hours to lie down, so to speak, a long-life fan. The Tubinenteil with the blades can be made to clean up from the back, with a jerk (the finger rausdrücken to the frame and with the thumb) from the frame - is better to clean (do not worry it is not broken).
My conclusion - gleiles part - about the price / performance ratio is okay - Quality costs just sometimes. Five stars from me!
