Thanks for this, yes,it does seem like a plausible explanation - and I've found a few northbridge coolers on Amazon, including a flower passive one from Zalman, quite well rated, and a wonderful heatpipe one with a fan in it. Quite large, have to check if it will fit. Quiet PC carries this as their sole northbridge cooler.
Apparently soutbridge is not a problem as its heat output is very low.
So thanks, will have a go.
