Can anyone recommend a good heatsink for this if they are using the stock northbridge chipset heatsink? I want to get a better heatsink instead of the tiny stock one that comes with Intel CPUs. Although I am afraid some of the larger ones will get in the way of the NB chipset sink.

I am looking to do some overclocking but unable to water cool at this point so I am not expecting much. I have a Q9450 and hear they overclock pretty well without extreme cooling.
