I have been having some stability problems with my computer, so in the process of investigating it, I noticed something. All the heatsinks I have right now are cool to the touch except for the northbridge, which is extremely hot. For reference, here is my system http://hardforum.com/showpost.php?p=1029390158&postcount=855 . Is there any reason why this would be happening? I'm not overclocking and I have decent ventilation. Thanks for the help.
