Sorry to hear that fellow Sniper owners are having trouble with their fan controllers. Antonio8, I think you do have a problem there. If you tried all the connectors and didn't get a change, it's a good bet that it's defective.
I'm posting some shots of my case for official membership. I was in the market for a case and saw an advertisement for the Storm Sniper at Microcenter. When I read how all the intakes are filtered (screened) and that it was tool-less with huge intake and exhaust fans, I was sold. The fan/LED controller was a bonus plus the fact that you can remove the hdd cage (I did).
My temps are almost exactly the same with my Antec1200 and I thought that case was good! I can't understand how the Sniper can cool so well with that HUGE screened opening in the side panel but the results speak for themselves. I originally had (2) 120mm fans in the side door but took them out as they did NOT change temps!
I can idle my C0 (3838A) i7 with the fans turned all the way down. Temps are 35c-36c at idle
