Can someone who has tried it, tell me how much colder the NB and SB will get if I use some third party cooler on them? Also will that mean both a heatsink and some noizy small fan on top of it?

In short; what are my options and how much colder will the bridges get?

Edit:
Dont also the original heatsink thingy also cool some other components? Not just the bridge chips?..
