For connection of 2 fans with 3-Pin connectors to a 3-Pin connector (e.g. on the Mainboard). Please note that the speed monitoring of only one connected fan is possible with this adaptor cable. A white sticker on one of the cables shows which connector can be monitored. This cable is not only practical, it is also optically appealing, The surrounding mesh, also called sleeve, which is surrounding the cable itself offers the advantages that every Pro-modder is looking for: A completely unique look, even of the cables in the system! Special attention was paid to the combination of cable connectors, sleeve and heatshrink which were used to ensure great design and a unique as well as elegant look. Phobya's goal is to make the work of professional and hobby modders a bit easier with these cables. Sleeving is a lot of work and requires much time. But with these cables by Phobya the whole system can be redesigned any way you like by simply adding these cables.
