Yes that's a typical Dell setup, the heat sink that you linked has an odd sized fan (95mm) and you would be better off with a 120mm or even 140mm. The smaller the fan the faster it has to spin so it makes more noise. Some of the quietest case fans are the 230mm and 200mm fans, so a 120mm o 140mm would be quieter then that 95mm.
I would go with this one unless money is an issue.
