Just bought 2 brand new BeQuiet silentwings3 fans for my antminer s5. on for the front, one for the rear. they are 4- pin fans. when I power my miner up they wont turn on. I know the power source is good because the stock fan works fine. can anyone tell me whats wrong? will only certain fans work with an antminer s5 Please help. I have to have a quiet fan due to antminers location. thank you.
