The fatality is very large and fits less MBs overall than the 9500 series. It depends on how much room you have around the cpu socket. The fatality heatsink fan sits low and is wide and large. It does not fit a lot of MBs. In addition, the fan blows straight down on the MB instead of expelling air out the back of the case like the 9500s do. I use mine on an old MSI NF4 Platinum board. It's amazing the thing even fits on there. Cools my FX55 though.
