Custom coolers certainly are better. Clicky
As I also said, stock coolers make much more noise than aftermarket coolers. The fan that came with the stock cooling on my XFX card @ 100% is a friggin leaf blower in my PC, strapped a Zalman VF900 on the card and its not only silent, but cools my card better to the tune of 7c @ load.
