Hi,
I keep reading in this forum about high North Bridge temperatures..I did install a dedicated fan to blow air around the Gigabyte NB heat sink,which helped a lot for my system..During an off time I decided to remove the Mainboard and investigate..I removed the NB Heatsink and to my amazement, I discovered a very very thick silvery TIM about 1 MM thick..Way too thick for excellent thermal conductivity..All literature says the TIM paste should be just enough to cover the entire chip and thin enough to maintain good thermal conduction..I wonder if the Two Spring mount for the HS allows enough rocking as the reason for the GB  engineers to do this...Surely  the position of the HS may under certain circumstances may not be entirely flat and tight against the chip..
Some think the High NB temps may contribute to instability..I will leave that to the experts on this forum and Gigabyte..
I offer this information just as a "heads up" if you have a problem..I do not suggest you all rip out the board but as a minimum inspect to see if the HS is flat and and tight against the chip..Oh and a dedicated fan on the NB heat sink in my opinion is a must..
This board is void of thermal heat pipes and the possible problems that may result..
Goodluck all,
jolphil

look my old post :

run very fine with the stock cooler !!

your problem is because i think that your cooler not send airflow to the NortBridge ...

Yes often this is the problem and is caused by people trying to do the right thing and fitting an aftermarket cooler as an improvement over the stock item. However often this directs the air in  a different way and evenm though the CPU ends up being cooler the surrounding chipsets end up with less air passing them and sometimes this then requires a seperate cooling solution.
