Four and a half years ago I had a tower built with the Thermaltake V5 case. Recently I've replaced graphics cards and fans as things get old and worn out. The problem lies with the top case fan. It says that it comes with 200 x 200 x 20 mm Blue LED fan, 800 rpm, 14dBA x 1. However when I bought a 200mm today I found out that it was much bigger and subsequently the mounting was not the same.
Has anyone else had this problem? And where can I find an exact replacement or one that will work. I've searched for hours but sadly seem lost. Any help is appreciated.
