Ok well, i got a 4500 rpm CPU fan that runs 100%... but my CPU still overheats... SO i kinda modded it a little... i had another CPU fan laying around so... i superglued it ontop of the cpu fan thats on my heatsink now and connect it to my other fan controller... now both fans at 100% and at 6000 RPM. Now will this burn out the fans since its going past its default RPM??? oh and my cpu is super cooled now woohoo!!
