Yes I use stock fan heatsink the heatsink has heatpipes big old thing,have 6 120mm fans in case,got to admit this case is built solid and easy to work with.plays flight sim x on settings of 50% no problem,but in my opinion the sim needs alot of fixes,to old and lazy to tweek it all day.lol,plays empire total war max setting no problem at all,best of all plays sh4 maxed out with mods,without even working very hard,beats my old intel 6550 cpu to blank,never another dell this is way to go.build it yourself its not very hard.oh yeah joint operations is super fast but then again that game has more cheats runiing around then probly any other.lol
