The North Bridge use to get hot, but not so hot that you couldn't touch it for 8 seconds so hot you can't hold on to it.
Now it's getting so hot that it is starting to smell like new electronics with that starting of a burnt smell.
Purchased Motherboard November 2012
So do I have a NB chip failure?
Do I need to send it back?
Main Hardware Information:
CPU (AMD / FX 6100 / FSB Speed: chips default / Voltages: default)
RAM (G.Skill / F3-14900CL9Q-16GBXLl / DDR3-1866 / Voltages 1.5 / Number of Sticks: 4)
Motherboard (Gigabyte /990FXA-UD3 (Rev: 1.1))
Video Card (Nivida /(2) GTX 550 Ti / default settings / Shader Speed: Default / Memory Speed: Default)
PSU (Corsair / 850 Gold / Max Wattage: 850 / Amperage: ?)
Other Hardware Information :
Monitor: Acer 23 LCD
HDD/SSDs: SSD for OS, and HDD for games and storage
Other PCI/PCI-X Cards: NONE
Optical Drives: NONE
Software Information:
Operating System :Win 7 SP1
Video Card Drivers in Use ( and tried ):WHQL last 3 within 2 months
Motherboard Drivers Used:Bios F8- F10a
All major components check 100% after thorough testing ( eg. Memory & Memtest86 ):TESTS GOOD
System clean of viruses / spyware etc:CLEAN
Other things tried: Can use a household fan blowing hard on it to get it cool so side is off till what course of action can be taken.
P.S. I never over clock I always use BIOS stock default settings.
All Bios setting have been "Auto", since construction, all voltages are reading within spec.

The NB chipset is able to take (AS PER DATASHEET on the AMD website) 95 Celsius temperature as maximum and 115 as absolute maximum.
So it will work even at 115 Celsius.
70 Celsius you are experimenting is no problem.
Just make sure there is ventilation in the case.
Additionally you can replace the thermal pad on it s heatsink.

Concerning case ventilation hence temperatures it's most important to make sure the air throughput is sufficient - meaning you got same amount of fans working as blowers (input) and suckers (output). Any imbalance can cause higher temperatures especially when you got more blowers than suckers in the case (oven effect).

The Northbridge on my 1.1 had the same problem. They use a cheap thermal paste dab and a sticker-type foam chipset protector. My board is out of warranty, so I replaced the thermal compound. Voila! Cool temps!
I had to find plastic heatsink spring rivet push pin fastener things that fit, though.
