Alienware M17X R4 Heatsink Mod

Someone has already made a watercooled m18x. They explain that the standard heat pipes can't handle the heat/liquid.

Yes, that is the video I am basing my mod on. This would be on 17 and I wondering if there would a good heat distribution if I connect them this way. Or will it run the same after the water cooling mod is added.
