Recently I bought a pair of Silenex 120 mm case fans for my case. They are meant to replace two aging and dying loud as shit antec case fans that have been getting on my nerves. I thought the install would be simple. Well I screw them in, get them physicly set up and boom the computer boots but regardless of how they are plugged into the PSU they do not spin. They simply sit there. I thought maybe I didnt have enough power in my PSU so I plugged my old 3850 back in with my new 650w PSU (was using 430w before with 3850) and they still refuse to spin. What is the problem here its killing me!
