Northbridge Overheating - What's the Cause?

Alright, I'm in a pickle here. Basically, I have noticed that under playing intensive games (namely The Sims 4, Civilization 5, Cities Skylines) my game has begun to be a meanie and re-emerge by freezing and reseting (effectively adding an entry in the BLueScreen Viewer, therefore, I'm blue-screening again) BSoD viewer shows NOTHING useful (points to error 0x0000124 and ntokrnl.exe or whatever.

However, I have been keeping an eye on my temperatures and I have noticed something somewhat peculiar.

When I start playing games, the tempreture of my Motherboard ( ASUSTeK Computer INC. M5A78L-M/USB3 (AM3R2) begins to steadily raise (slower in some games, quicker in others, takes about 2-4 minutes in Skylines) up to 73C degrees. IF I exit the game before the game/PC hangs, it will VERY QUICKLY drop back down to the averaeg idle of about 40C. If I recall, my GPU (NVIDIA GeForce GTX 660 Ti) goes up to about 70C (35C when idle) if not less (I wasn't paying attention) and my CPU (AMD FX-6100 6-Core 3.3ghz if I recall) goes up to about 65 C. (25C when idle).

My Powersupply I believe is 500 W (yes, I know it is quite low) and I have 8GB of RAM.

So.. would anyone have any accurate insight into why my Northbridge (or my motherboard) would overheat so quickly when playing games (at this stage I am pretty much considering replacing my mobo, I got the money, I might as well) but I still don't understand why it overheats.

My overall air flow shouldn't be bad (I have 3 fans, on on the lower front, one in the upper back, and one on the top of the case adjacent to the upper-back one).

My dad has a theory that the Motherboard simply isn't strong enough to handle all the pressure, so any insights, I would greatly appreciate.
 
Solution
Normally poor cabling that restricts air flow causes the northbridge to heat up. It can also be caused by bad vrm's but clean your case with compressed air and move cabling to see if getting some air flow to the area helps. Even a fan aimed in that direction would help move the heat away.

It's already been cleaned and made no significant difference. I don't think it is poor cabling, since there's plenty of room around the actual motherboard (I can see into the case). and I really don't think the general air flow is bad if the other components don't seem to really heat up as much. But I will re-consider your suggestions.
 
Actually it was really (or it seems) that the problem was terrible Air flow. I opened up the case (the side) and let a big fan blow air into it, eventually the Mobo's temp reached a high point of 67/65C before it just stayed there. (I also had my window open) but it was really getting warm in here. So I guess I need to find a way to keep the Mobo cool.

Just reference points
Temps when playing Cities skylines.
CPU 60C
Mobo 65C
Graphcis 64C
Storage 24C
 


Thanks for letting everyone know what helped in your situation. That may help others with overheating issues see that cable placement can indeed cause issues.
 
Could've been, I haven't actually played around with the cable, i literally just opened up the side of my tower and let a big fan blow air into it and it helped by making the Mobo reach a temp of 65C before staying there.
