The adapter cable does the job perfectly. The fan (which are operated at 5 V) are almost inaudible. However, the Molex connector is very tight and when pulling a ferrule of the plug is herausgeflutscht. But you could be relatively easy in its original position. It leaves no residual damage. The fan connector on the other hand are a little too easy. All in all, the product of the price but top and there is no defect that would lead to the purchase of another product.
