Would putting a fan that moves more air on a stock heatsink help any?

This seemed the most relevant place to put this.

I'm noticed that compared to the rest of the fans in my case, my CPU's stock Heatsink and fan make the most noise.
And I was considering getting a quieter fan that -maybe- moves more air.
But if moving more air on a stock heatsink doesn't help at all/ Very little, I would just opt for a quieter fan.

The reason I'm not thinking about a completely new hheatsink is cause I'm somewhat broke.
So just a fan would be cheaper.

If you want to to be quiet get the biggest fan you can fit on it, smaller fans make more noise usualy because they have to spin faster to move any amount if air. The fan on my 4830 for example makes more noise when it spins up than the other 7 fans in my case combined. I would opt for a new heatsink with a 120mm fan is you want it to be close to silent. Or find a way to mount a 120mm fan to your stock heatsink.

Higher CFM should be better, but it also needs to be able to move the air through the heatsink (higher static pressure). Not all fans are equal in this respect.
