Corsair 650D fan controller buzz/scrath sound?

Hey guys

When play and use my comp with my 650D chassi it somtimes and during long periods of gaming make a wierd buzzing or scrathing sound from the controller area.

I saw its a problem and early versions of it have this problem and well I bought mine early so its probebly that. However i dont think its fair that I should pay for the shipping to sweden 15 $ or something it costed since its your chassi that is produced faulty.

I would like that fix for free so it doesnt make that sound again and it kinda destroys the hole point of a fan controller and my outher fans which I bought extra to be extra quite and low noise.

Please respond here and to my mail eric.sundell2@gmail.com
