Initially connected without the extension: a disaster level noise (the successors plugged into an extension cord, I could not even regulate with the motherboard ...)! Once the extension set are virtually inaudible ... the problem is that they are also much less visible (and effective ...) Therefore, do not hesitate to put a number to have good ventilation and some noise!
For my part I have mi 3 in addition to those origins. In the end the case is very well ventilated although it is full.
In short, if you want a blue led fan Flachi good and quiet, it will go see BTW ...
