I've noitced my system become unstable over the past few days, and i believe its due to the passively cooled northbridge on my mobo. Its very hot when i touch it, but i have no way of measuring exactly how hot. There isn't much airflow over the chip itself, and the heatpipe heatsink is near my sythe ninjas 120mm fan, but doesn't seem to be cooled well either. I was wondering if the northbridge is designed to run v hot? or any suggestions on how to cool it?
