I know how you feel, My front fan module is making the same noise, and I can't for the life of me find any sort of replacement parts. I guess I'm a little luckier, because you can pretty easily remove the front fan module but no one sells a replacement so its not very helpful. I was thinking about trying some WD-40 on it, but I'm very reluctant to do that, because I'm afraid once the fan starts spinning its gonna go every where inside the case.
