I upgraded on a budget and am running a Gigabyte GA-P35-DS3L and finding the northbridge heatsink getting almost too hot to touch. I've got an 80mm intake fan (in two 5 1/4 bays) and an 80mm exhaust fan, but think I need something else. The heatsink isn't level, its a half circle so putting a small fan on won't work the best. I was just wondering what other people have done that is quiet and cheap to do.
