Review on 4-Pin PWM Fan Power Supply Cable 1 to 5 Splitter Hub for ATX Computer Case, Internal Motherboard Fan Extension, 5 Way Splitter Cord Wire for 4-Pin and 3-Pin Cooling Fans, 13 inch, Black by Tutan Beatz

Update - ordered another one. That works fine. I would say the 3M foam adhesive backing is very thick. It was fine for the build I used it on, but many users may have trouble placing it on the back of their case. I would also like to say that you should also offer a longer version for sale. Works as needed but only delivers 4 due to 2 minor things. Firstly I would say the length is good and secondly the glue isn't that good. So it's highly recommended to make sure you know where you're going to place it.
