I bought my cyberpowerpc off walmart last year and i like it besides the terrible graphics card and the annoying CPU fan. I know cyberpowerpc has a 3 year warranty and I could get the CPU fan replaced but I am not sure that it will fix anything. It is a thermaltake cpu cooler and it is annoyingly loud. It is 70mm cooling my amd fx 4100. Can someone please provide me with some fan substitutes that are going to be quiet and still keep my cpu cool? My motherboard has a 4 pin setup though i have never worked with bios before.
