First the positives: very good packaging, very quiet operation, very fine workmanship, simple installation, eventual hum of the pump I could not perceive yet.
Unfortunately there are also some negative (in my eyes): Manual very spartan, no software (only a reference to download, with the price a small media would certainly have been possible), the Y-cable to connect the fans seem very cheap, while Installation I had equal 2 times the contacts in your hand, these dissolve well very quickly from the plug, I have the fan connected to the motherboard, it achieves the same effect, as long as you use a software for controlling the fan.
The included fan I have 120 fans (also from CORSAIR) exchanged for SP, a good decision, because the package containing the fan very quickly, according to (test with DME Y-cable and the CORSAIR Software)
However, I am very satisfied with the Kühlnug and would you like to recommend.
