Thats going to be hard, as there is heatpipes on both sides of it which makes it pretty impossible to do unless there is a recommended heatsink & fan that will overclock better and also fit more easily as well?

Not sure what else you will need to know, thats all I can think of.
Wish there was someone that could do all of the mods for me, someone that knows what they are doing as im not sure I would be good enough to play around with it. In saying that, this rig will have to last me another year before a big upgrade to bring me upto speed with everything
