Hello, I bought Thermaltake Urban T81 PC Full Tower Case. After 2 months the fans stopped to work. I was so afraid that they are died. But when I disconnected them from the fan hub that included on the case and just connect them directly on motherboard they worked fine. I would like to ask you kindly, could you please send me a new fan hub and thank you. If you accept and it will be appreciated I will give you my address.
