I just bought the Commander series C35 case and love the over all design. BUT a HUGE complaint. they supply a 2 200 mm fans for the front with a proprietary 5 pin connector. There is no fan speed control of any kind. I use 140mm and 120mm Pure Plus fans carried over form my last case. and use the included 9 pin controller. Is there a solution from thermaltake? I have yet top find one. From the looks of other forum posts i am not alone. The other posts have gone unanswered from Thermaltake themselves. I bought the case for the design and value of it. Kinda disconcerting that Thermaltake has taken a deaf ear to its consumers. Some forum posts have gone unanswered for 3 weeks or more
